Die papillaren und subpapillaren Gefe der menschlichen Haut sind Endothelrohren mit auen aufgelagerten, zur Gefrichtung mehr oder weniger schrg liegenden Zellen. Die betr. ueren Zellen sind als Muskelzellen aufzufassen, indem sie ihrer Lagerung nach eben mit den contractilen Capillarmuskelzellen — denRougetschen Zellen — der kaltbltigen Tiere homolog und analog sind. Die papillaren und subpapillaren Gefe drfen nicht als muskellose Arterien und Venen aufgefat werden, wren eher vom anatomischen sowie vom physiologischen Gesichtspunkte aus als Capillaren zu bez...

We have examined the organization of pontine, inferior olivary, lateral reticular and vestibular nuclei in the brainstem of the short-beaked echidna (Tachyglossus aculeatus) to determine if the cyto- and chemoarchitecture of these nuclei are similar to that in placental mammals and marsupials. We have used Nissl staining in conjunction with enzyme-histochemistry for acetylcholinesterase, cytochrome oxidase and NADPH diaphorase as well as immunohistochemistry for non-phosphorylated neurofilament protein (SMI-32 antibody) and calcium binding proteins (parvalbumin, calbindin, calretinin).

Aorta-associated c-kit-positive cell clusters can be observed first in 23 days post inseminationem (dpi) bovine embryos and disappear after 34 dpi. For the first time, it was shown that the immunophenotype of these aortic cluster cells changes during embryonic development. Aortic cell clusters are c-kit+/CD45-/STA−, when they are first detected in the 23 dpi embryo, and acquire a c-kit+/CD45+/STA− phenotype in 27–29 embryos and a c-kit+/CD45+/STA+ immunophenotype in 32–34-day-old specimens. Cell clusters are most prominent in the vicinity of lateral and ventral aortic branches, but rare in omphalomesenteric arteries and absent in Aa. umbilicales....

Sulcus formation began with the appearance of the lateral fissure on embryonic day (ED) 70, followed by delineations of four cerebral lobes by the emergence of the parietooccipital sulcus, central sulcus, and preoccipital notch on EDs 80–90. The following primary sulci were then visible until ED 120: the superior temporal sulcus on ED 90; the intraparietal sulcus, lunate sulcus, inferior occipital sulcus, and arcuate sulcus on ED 100; and the principle sulcus on ED 110; the occipitotemporal sulcus, anterior middle temporal sulcus, and superior postcentral dimple on ED 120.

Almost all nuclei of the Am contained NADPHd-positive neurons and fibers, but the somatodendritic morphology and the intensity of staining of different subpopulations varied. The strongly stained neurons displayed labeling of the perikaryon and the dendritic tree with Golgi impregnation-like quality, whilst the dendrites of the lightly stained neurons were less successfully followed. Many strongly positive neurons were located in the external capsule and within the intraamygdaloid fiber bundles. A large number of small, strongly stained cells was present in the amygdalostriatal transition area. In the Am proper, a c...

Double immunofluorescence protocol was used in order to determine whether there is colocalization of CB and nNOS. The CB-immunoreactive (IR) neuronal population was composed especially of non-pyramidal neurons, but a few pyramidal cells were also present. The non-pyramidal neurons showed a multipolar and, occasionally, a fusiform morphology. The comparison between single-labeled CB-IR non-pyramidal neurons and cells belonging to CB-IR neuronal population showed they were identical for morphology, mean size, and distribution. The single-labeled CB-IR non-pyramidal neurons were ...

In aim to analyze activity of the Hsp70.2/Hst70 promoter in developing embryos we have constructed transgenic mice expressing EGFP reporter gene under control of the rat Hst70 promoter. The appearance of EGFP fluorescence coincides with series of major developmental events, such as extra-embryonic membranes formation, axial rotation, formation of neural tube and the primordium of central nervous system, formation of differentiated somites, extensive remodeling of the heart, development of fingers and toes, and sensory organs formation.

Pax3 lies genetically upstream of MyoD and has also been shown recently to directly control Myf5 transcription in derivatives of the hypaxial somite, where it also plays an important role in ensuring cell survival. Both Pax3 and Pax7 are expressed in myogenic progenitor cells derived from the central dermomyotome that make a major contribution to skeletal muscle growth. In Pax3/Pax7 double mutants, the myogenic determination genes, Myf5 and MyoD, are not activated in these cells which become incorporated into other tissues or die. This again demonstrates the dual function of Pax factors in regulating the entry of progenitor cells ...

The phenotype of m865 mutant embryos shows defects in the development of dopaminergic neurons in the pretectum and of retinal amacrine cells, as well as abnormal caudal dopaminergic cluster in the diencephalon. The effects of the mutation appear not to be restricted to dopaminergic neurons, as development of other neurotransmitter systems (serotonergic and cholinergic) is impaired as well. Furthermore, increased apoptosis is localized to the m865 mutant retina and in the optic tectum starting at 24hpf, and may lead to the observed reduced size of the mutant head an...

Here, we analyzed the expression pattern of various BMPs (2, 4, 5 and 7) by whole mount in situ hybridization during chick limb development. In limb, expression of BMPs suggests evolutionary conserved mechanisms of BMP-dependent differentiation between lower and higher vertebrates. During the early developmental stages, BMP-2 and BMP-7 are expressed in the posterior distal mesenchyme leaving a less prominent expression anteriorly. BMP-4 is initially expressed in the anterior mesenchyme and spreads later to the whole mesenchyme leaving a stronger expression at the anterior side. From HH-st...

The somite is initially naive in terms of its fate restriction as shown by grafting and rotation experiments whereby ectopically grafted or rotated tissue of newly formed somites yielded the same pattern of normal derivatives. Somitic derivatives are determined by local signalling between adjacent embryonic tissues, in particular the neural tube, notochord, surface ectoderm and the somitic compartments themselves. The correct spatio-temporal specification of the deriving tissues, skeletal muscle, cartilage, endothelia and connective tissue is achieved by a sequence of morphogenetic changes of the paraxial mesoderm, eventually leading to the three transitory somitic co...

Therein is contained the road map for growth, proliferation, differentiation and morphogenesis. The cellular transportation machinery plays a major role to ensure that all the components for transcription and translation are available at the right place at the right time. Nucleolar complex associated protein2 (NOC2) has a highly conserved UPF0120 domain, and is an element involved in ribosome transportation from the nucleoplasm to the cytoplasm. However, its gene expression pattern is still unknown. We chose the developing chick embryo to investigate the possible involvement of avian NOC2 (cNOC2) in developmental processes, particularly neurogenesis and myogenesis. For t...

In relation to Parkinson disease, we suggest that this increase is associated with the akinesia or lack of movement seen in patients.

In amniote species like mouse and chick, somite development has been the subject of intense research over many decades, giving insight into the morphological and molecular processes leading to somite compartmentalization and subsequent differentiation. In anamniotes, somite development is much less understood. Except for recent data from zebrafish, and morphological studies in Xenopus, very little is known about the formation of somite compartments and the differentiation of somite derivatives in anamniotes. Here, we give a brief overview on the development of myotome, sclerotome and dermomyotome in various anamniote organisms, and point out the different mechanisms of somite development be...

Its structure has changed greatly during evolution. For example, in humans it is a large quite flat triangular bone whereas in chicks it is a long blade like structure. In this review we describe the mechanisms that control the formation of the scapula. To assimilate our understanding regarding the development of the scapula blade we start by addressing the issue concerning the origin of the scapula. Experiments using somite extirpation, chick-quail cell marking system and genetic cell labelling techniques in a variety of species have suggested that the scapula had its origin in the somites. For example we have shown in the chick that the scapula blade originates from the somite, while the cranial part, which articulates with t...

Here, distribution, number and fate of binucleate neurons were examined in younger, developing capybaras, aged 3 months. The mean neuronal cross-sectional area was 575.2 μm2 for mononucleate neurons and 806.8 μm2 in binucleate neurons. Frequency of binucleate neurons was about 36%. The mean ganglion volume was about 190 mm3 in young capybaras and the mean neuronal density was about 9,517 neurons/mm3. The total number of neurons per ganglion was about 1.81 mill. Neuronal cell bodies constituted 22.5% of the ganglion volume and the average neuronal volume was 23,600 μm3. By comparing t...

Here, we review the current picture of this segmentation clock and gradients, and use this knowledge to critically ask: What is the basis for periodicity and directionality of somitogenesis?

Subsequently, using electron microscopy and histological procedures, Bodo Christ identified that cells of the somites undergo an epithelial to mesenchymal transition which enabled them to move from their paraxial point of origin to distal locations. These studies defined this translocation as one of the major mechanisms allowing myogenic cells to translocate around the body. The other means used to translocate muscle involves the movement of cells as a sheet. The deployment of one of these two mechanisms has been postulated to be involved in the formation of all the hypax...

The goal of the present study, therefore, was to evaluate the influence of age on the sympathetic innervation of the myenteric plexus throughout the gastrointestinal tract. Ad libitum fed virgin male Fischer 344 rats at 3, 15–16, 24, and 27–28 months of age were sampled. Whole mounts of the stomach, small intestine, and large intestine were processed with an antibody to tyrosine hydroxylase (TH). Additionally, some specimens labeled for TH were stained for NADPH-diaphorase to selectively label the nitrergic subpopulation of neurons in the myenteric plexus. Age-related changes in t...

They are the most obvious correlative of the segmental patterning along the cranio-caudal axis and transfer segmentation to other tissues such as the spinal nerves and dorsal aortic branches. Furthermore, somites are the source of numerous mesodermal cell types such as smooth and striated muscle, cartilage and tendon cells, and soft connective tissue. They also give rise to endothelial cells. Here we focus on the finding that two lineages of endothelial cells, blood vascular endothelial cells and lymphatic endothelial cells are derived from the somite. Their precursors, angioblasts, and lymphangioblasts, respectively, are born in the somite at different time points. Angioblasts are ...

Migrating precursors are generated on particular axial levels only, i.e. occipitally, cervically, and on the levels of the fore and hind limbs. They express the homeobox gene Lbx1, which provides a useful marker for their visualization. In the mouse, migrating precursor cells give rise to muscles of the extremities, the hypoglossal chord, and the diaphragm. We discuss here the development of this migrating lineage, which critically depends on the correct specification of the precursors in the dermomyotome, their delamination and correct migration. Finally, proliferation at the targets is essential to ensure a correct size of the precursor pool a...

Here, we studied a novel case of a severe congenital myopathy with a failure of myotube formation. Polymerase chain reaction-based analysis was performed to characterize the expression patterns of the Desmin, p21, p57, and muscle regulatory factors (MRFs) MyoD, Myf4, Myf5 and Myf6 in differentiating skeletal muscle cells (SkMCs), normal human fibroblasts and patient-derived fibroblasts during trans-differentiation. The temporal and spatial pattern of MRFs was further characterized by immunocyto- and immunohistochemical stainings. In differentiating SkMCs, each MRF showed a characteristic expression pattern. Normal trans-differentiating fibroblasts formed myotubes and expressed all of the MRFs, which were detected. Interesti...

This sets the grounds for elucidating the mechanisms underlying differential cell specification and morphogenesis. By examining the in vivo roles of N-cadherin on discrete domains of the somitic epithelium at various times, our recent studies highlight the existence of a regional and temporal heterogeneity in cellular responsiveness. As examples of this assortment, we document a coupling between asymmetric cell division and fate segregation in the DM sheet, sequential effects of N-cadherin-mediated adhesion on early myogenic specification compared to later myofiber patterning, and a differential behavior of pi...

Immunohistochemical analysis shows that SBG is present at the apical surface of isthmic and ampullar epithelial cells. The presence of SBG is limited to the upper two-thirds of the crypts of the isthmus and to cells located near the oviductal lumen in the ampulla. The ratio of the amount of SBG detected by western blot is 1:3 (ampulla:isthmus). Sperm entering the Fallopian tube probably contact the epithelial cells at the lumen before they reach the cells at the bottom of the folds. In vitro sperm can bind to isthmus and, at less extent, to ampulla. Thus, the localization and the relative amount of SBG in the isthmus and ampulla of pig’s oviduct are compatible with its possible function in...

However, in the early postnatal period, the rat parotid gland shows many myoepithelial cell bodies around the acini, including the intercalated ducts. In order to clarify the reason for the disappearance of myoepithelial cells from the area around the acinus during postnatal development, changes in the number and distribution of myoepithelial cells in the rat parotid gland were examined histochemically and chronologically, with particular reference to cell proliferation and cell death. From day 7 to day 14, many myoepithelial cells showing a positive reaction with anti-actin antiserum were found around the acini and intercalated ducts, but ...

In the present paper, we delineated the development and frequency distribution of the taste buds as well as the immunohistochemical expression of α-gustducin, a G protein closely related to the transduction of taste stimuli in the fungiform papilla from the birthday till the age of week 9. At birth, more than 45 taste buds (with or without pores) were observed on the fungiform papilla, then the number of mature taste buds increased rapidly, and resulted in 66% (80.2 ± 0.6 of 122.2 ± 1.3) of fungiform papilla taste buds containing ta...

At the ultrastructural level, vimentin immunoreactivity was seen concentrated around the nuclei, along fibrillary material within the cytoplasm and at the ectoplasmic specializations of the Sertoli cell junctions, as well as throughout the periphery of the Sertoli cell processes. It is therefore well suited as a marker for Sertoli cell configuration. In computer-aided 3D reconstructions of 20 serial sections, Sertoli cells displayed particular configurations of intermediate filaments in the different stages of spermatogenesis. Two basic configurations, nam...

HRP was administered to the cut end of the optic nerve and the morphological characteristics of HRP-filled ganglion cells were analysed in retinal wholemount preparations using computer assisted morphometry. Ganglion cells were classified according to their soma size, dendritic branching pattern, dendritic field and the number of shaft dendrites. Ganglion cells were divided into 3 major classes on the basis of soma sizes and extent of dendritic field: large (soma size, mean 258.04 μm2±52.03 SD; dendritic field size 0.104 mm2±0.23), medium size (126.7 μm2±37.01; 0.041 mm2±0.013) and small (87.3 μm2±22...

Nerves are first seen in the larger portal vessels at day 1 after birth and reach their final distribution at 5 days after birth i.e. at the same time as the establishment of the acinar architecture and the heterogeneous distribution of NH3-metabolizing enzymes. The latter distribution of nerves is already seen at birth in the liver of the closely related but precocial spiny mouse. This shows that the onset of extrinsic sympathetic innervation is regulated by the developmental stage of the animal rather than by adaptation to extrauterine life. Chemical sympathectomy at birth with 6-hydroxydopamine did not eliminate the developmental appearance of heteroge...

Although our results indicate that the callosal pattern is clearly anomalous in these rats, all features of the normal visual callosal pattern are recognizable in mutant rats, indicating that central visual pathways can generate many aspects of normal interhemispheric connectivity in the absence of input from the periphery. On the other hand, the presence of anomalies in the pattern indicates that the eyes are necessary to finetune the distribution of callosal connections at some developemental s...

Each combination produced one of a variety of results ranging from completely normal vertebral formation, through fusion of various vertebral elements, to the absence of complete vertebral halves and the formation of hemivertebrae. Assessment of our operating ability showed that we were removing at least 90% of the somitic material and therefore these results suggest that there is a regulating mechanism available to the embryo, at least with regards to vertebral development. When two consecutive somites were removed, vertebrae frequently developed that were lacking certain elem...

In the femoral and mesenteric arteries, less than 10% of the endothelial cells showed positive immunolabelling for these substances. The distribution of serotonin and substance P in endothelial cells was similar in both arteries. The immunoprecipitate was confined to the cytoplasm, including subcellular organelles. The results are discussed in terms of endothelial mechanisms of local control of blood flow.

The morphology and distribution of nerve cells in the three regions, resembled those already known in other mammals. Distinctive cellular types were, however, present, such as extraverted pyramidal neurons in Layer II and giant multipolar and bi-tufted cells with smooth, beaded dendrites and extended, generalized axonal arborizations in Layers III and V. Spiny stellate cells were located in the inner region of Layer I...

We then determined whether the number of these two types of cells changes in rats treated for 5 days with compound 48/80, dexamethasone, a combination of compound 48/80 and dexamethasone, or saline. We identified globule leukocytes and mast cells in whole mounts and histological sections of rat tracheas by using a histochemical reaction that demonstrates the chymotrypsin-like protease (chloroacetate esterase) present in mast cell granules. Using this method, we found that aproximately 225000 globule leukocytes were present in the epithelium of the trachea. These cells were most abundant in the rostral trachea. Rats treated...

The impregnated granule cells were gold-toned allowing for a fine structural study of the same identified neurons and of the input synapses onto their cell bodies and dendrites. Due to the long postnatal formation of these cells it was possible to describe a sequence of maturational stages coexisting on the same postnatal day (P5). Characteristic features of the dendritic development of granule cells were i) occurrence of varicose swellings along the dendrites, ii) growth cones on dendritic tips, iii) transient formation of basal dendrites, and iv) progressive development of dendritic spines. Incoming synapses on the differentiating granule cells were mainly found...

After postoperative survival times of 1–25 days the number of non-neuronal cells and lipid droplets in each cell type in the posterior funiculus at L1 were counted at the ultrastructural level. Intact control animals were analyzed in the same way. The number of astrocytes and oligodendrocytes decreased with increasing postoperative survival time in the degenerating zone. This was also the case in the white matter of control animals with increasing age of sacrifice. However, in the degenerating zone of operated animals the decrease was more extensive for oligodendrocytes starting at 5 days after surgery, and possibly also for astrocytes at 25 days postoperatively. The number of ...

Up to stage 62, VCCs reveal a dense two-dimensional vascular network ensheating the intestinal tube, whose proximal portion forms a clockwise spiralling outer and its distal portion an anti-clockwise spiralling inner coil. Vessels of the intestinal network impose flat and run circularly to slightly obliquely. Locally, dense capillary plexus with small “holes” indicating ongoing intussusceptive microvascular growth (IMG) and vessel maturation, are present. The typhlosole, an invagination alo...

NPY-LI fibers are observed throughout the encephalic dura mater. A remarkable net of NPY-LI nerve fibers is located in the walls of the sagittal and transverse sinuses. Beyond that NPY-LI network, distinct NPY-LI nerve fibers or plexus occur in the rostral falx, parietal dura mater of the olfactory bulb, supratentorial dura mater, parietal dura mater of the cerebellum, tentorium cerebelli and the ventral dura mater. Electron microscopic studies reveal that NPY-LI is exclusively located in unmyelinated axons of small and large ner...

The repair process observed (in contrast to that in adults) was characterised by minimal haematoma formation or cell death and the absence of formation of either cellular blastema or fracture callus. Re-epithelisation was complete within 48 h with no scar tissue formed. Continuity of Meckel’s cartilage, together with restoration of its histological appearance and that of the surrounding soft tissues, was re-established within 24 h in 88% of cases. In the case of the cartilage this was due to fusion of the matrix followed apparently by chondrocytic and perichon...

Kidneys perfusionfixed with glutaraldehyde were studied with light- and electron microscopy. Cryostate sections from kidneys immediately frozen in liquid nitrogen were studied with respect to the expression of MHC class II antigen using the monoclonal antibody OX6. The interstitial space of both the renal cortex and the outer and inner medulla was prominent during the first days postnatally. The relative interstitital volume of the cortex and outer part of the medulla then decreased in conjunction with the outgrowth and maturation of the superficial nephrons while the inner medullary interstitium remained wide. During the first post... Anatomy and Embryology journals http://www.medworm.com/rss/comments.php?id=179149 Fri, 28 Jul 2006 08:34:11 +0100 179149
