Immune balance at the foeto-maternal interface as the fulcrum of reproductive success
Abstract: Viviparity has many evolutionary advantages but brings with it the problem of the semi-allogeneic foetus having to coexist with the mother for the duration of pregnancy. In species with haemochorial placentation this problem is particularly evident as foetal trophoblast cells are extensively intermingled with maternal tissue and are directly exposed to maternal blood. Fascinating adaptations on both the foetal and maternal side have allowed for this interaction to be re-directed away from an immune rejection response not only towards immunotolerance, but in fact towards actively supporting reproductive success. R...

Pregnancy-acquired fetal progenitor cells
Abstract: The transfer and persistence of fetal progenitor cells into the mother throughout pregnancy has sparked considerable interest as a trafficking stem cell and immunological phenomenon. Indeed, the intriguing longevity of semi-allogeneic fetal microchimeric cells (FMC) in parous women raises questions over their potential clinical implications. FMC have been associated with both immune-modulatory roles and participation in maternal tissue repair. Although their influence on maternal health is as yet unresolved, FMC selectively home to damaged maternal tissues and often integrate, adopting site-appropriate phenotypes...

The Effects of Substrate Elastic Modulus on Neural Precursor Cell Behavior.
In conclusion, limitations in NPC growth, proliferation, and neuronal differentiation were encountered when substrate elasticity was not within normal spinal cord tissue elasticity ranges. These studies elucidate the effect injury mediated mechanical changes may have on tissue repair by stem cells. Furthermore, this information can be applied to the development of future neuroregenerative biomaterials for spinal cord repair. PMID: 23429962 [PubMed - as supplied by publisher]

Nanomechanics controls neuronal precursors adhesion and differentiation
Abstract The ability to control the differentiation of stem cells into specific neuronal types has a tremendous potential for the treatment of neurodegenerative diseases. In vitro neuronal differentiation can be guided by the interplay of biochemical and biophysical cues. Different strategies to increase the differentiation yield have been proposed, focusing everything on substrate topography, or, alternatively on substrate stiffness. Both strategies demonstrated an improvement of the cellular response. However it was often impossible to separate the topographical and the mechanical contributions. Here we investigate the r...

Immobilized Heparan Sulfate for Embryonic Stem Cell Culture [Glycobiology and Extracellular Matrices]
As our understanding of what guides the behavior of multi- and pluripotent stem cells deepens, so too does our ability to utilize certain cues to manipulate their behavior and maximize their therapeutic potential. Engineered, biologically functionalized materials have the capacity to influence stem cell behavior through a powerful combination of biological, mechanical, and topographical cues. Here, we present the development of a novel electrospun scaffold, functionalized with glycosaminoglycans (GAGs) ionically immobilized onto the fiber surface. Bound GAGs retained the ability to interact with GAG-binding molecules and, ...

SON Regulates GATA-2 via MicroRNA [RNA]
SON is a DNA- and RNA-binding protein localized in nuclear speckles. Although its function in RNA splicing for effective cell cycle progression and genome stability was recently unveiled, other mechanisms of SON functions remain unexplored. Here, we report that SON regulates GATA-2, a key transcription factor involved in hematopoietic stem cell maintenance and differentiation. SON is highly expressed in undifferentiated hematopoietic stem/progenitor cells and leukemic blasts. SON knockdown leads to significant depletion of GATA-2 protein with marginal down-regulation of GATA-2 mRNA. We show that miR-27a is up-regulated upo...

REPORT: Derivation of hiPSCs from Patients with MODY [Developmental Biology]
Maturity onset diabetes of the young (MODY) is an autosomal dominant disease. Despite extensive research, the mechanism by which a mutant MODY gene results in monogenic diabetes is not yet clear due to the inaccessibility of patient samples. Induced pluripotency and directed differentiation toward the pancreatic lineage are now viable and attractive methods to uncover the molecular mechanisms underlying MODY. Here we report, for the first time, the derivation of human induced pluripotent stem cells (hiPSCs) from patients with five types of MODY: MODY1 (HNF4A), MODY2 (GCK), MODY3 (HNF1A), MODY5 (HNF1B), and MODY8 (CEL) with...

STK40 Contributes to Lung Maturation [Gene Regulation]
STK40 is a putative serine/threonine kinase and was shown to induce extraembryonic endoderm differentiation from mouse embryonic stem cells. However, little is known about its physiological function in vivo. Here, we generate Stk40 knock-out mice and demonstrate that loss of the Stk40 gene causes neonatal lethality at birth. Further examination reveals that the respiratory distress and atelectasis occur in the homozygous mutants. The maturation of lung and alveolar epithelium is delayed in the mutant, as indicated by narrowed air spaces, thickened interstitial septa, and increased glycogen content in the lungs of Stk40−/...

Nuclear transferred embryonic stem cells for analysis of B1 B-lymphocyte development
The transfer of nuclei of fully differentiated cells into enucleated oocytes is a well-recognized method for the generation of embryonic stem (ES) cells. Here, we demonstrate that nuclear transferred ES (NT-ES) cells can be established with high efficiency using innate-like B lymphocytes as donor cells. We established two mouse lines carrying rearranged immunoglobulin heavy and light chains using NT-ES cells containing nuclei from peritoneal cavity B1 cells.

Microfluidic devices for the isolation of circulating rare cells: a focus on affinity‐based, dielectrophoresis and hydrophoresis
Abstract Circulating rare cells have attracted interest because they can be good indicators of various types of diseases. For example, enumeration of circulating tumor cells (CTCs) is used for cancer diagnosis and prognosis, while DNA analysis or enumeration of nucleated red blood cells (NRBCs) is useful for prenatal diagnosis or hypoxic anemia, and that of circulating stem cells to diagnose cancer metastasis. Isolation of these cells and their downstream analyses can provide significant information such as the origin and characteristics of a disease. Novel approaches based on microfluidics have many advantages, including ...

Is extramedullary relapse of acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation associated with improved survival?
ConclusionsOur results suggest that EM relapse post‐HSCT has similar outcomes to BM relapses treated in a similar way. Furthermore, choice of therapy at relapse appears related to the time post‐HSCT that the relapse occurs, with BM relapses occurring significantly earlier post‐HSCT than relapses at EM sites.

Phenotypic Evolution In A Case of Peripheral T‐Cell Lymphoma Suggests The Presence of Tumor Heterogeneity
Abstract Peripheral T‐cell lymphoma (PTCL), not otherwise specified (NOS), represents a heterogeneous group of nodal and extranodal lymphomas that express a variety of T‐cell antigens indicative of mature T‐cell lineage. Most cases of PTCL express CD4 and lack CD8 expression and have a T‐helper immunophenotype. Although the immunophenotype of PTCL is usually stable over time, immunophenotypic switch or evolution from T‐helper to T‐suppressor or vice versa has been rarely reported. Herein, we report a patient who presented with nasal PTCL, NOS, that was CD8+ and negative for Epstein‐Barr virus, with concurrent...

Human testicular peritubular cells - more than meets the eye.
Abstract In healthy men several layers of inconspicuously flat cells and extracellular matrix (ECM) proteins build the wall of the seminiferous tubules. The cells of this wall, peritubular cells, are not well characterized. They are smooth-muscle-like and contractile and transport immotile sperm, a function important for male fertility. However, their full functional importance, especially their potential contribution to the paracrine regulation of the male gonad, is unknown. In men with impaired spermatogenesis the architecture of the tubular wall is frequently altered. Deposits of ECM and morphological changes of...

Evaluation of 16 SNPs allele-specific to quantify post hSCT chimerism by SYBR green-based qRT-PCR
The importance of monitoring post haematopoietic stem cell transplantation (hSCT) chimerism has been defined in numerous publications. Single-nucleotide polymorphisms (SNPs) are molecular markers that vary significantly among different populations. Allied to a very sensible technique, SNP assays seem to be very sensitive (0.001%) when post hSCT chimerism is measured. However, well known SNP frequencies are limited to certain populations, mainly in countries where there is a high level of diversity in its population, therefore restricting their use worldwide. Amplification by SYBR green based quantitative real time PCR of e...

Association between pterygium and plica semilunaris morphology
Ophthalmic pterygium remains an “enigma” despite numerous proposed pathogenetic theories, such as the molecular genetic alterations of stem cells located at the sclerocorneal limbus1. The nasal conjunctiva may be particularly exposed to environmental irritants due to the presence of the “lacrimal lake”, formed in the area of the plica semilunaris2. An edematous enlargement of the latter may result from chronic ocular surface inflammation3.
