Inside this issue
See Salem et al., pages 209–218, and Wolschke et al., pages 134–142. Multiple myeloma (MM) is a rare but devastating plasma cell malignancy that affects mainly older adults. In the last ten years, induction regimens that combine the glucocorticoid-analog dexametasone (Dex) with novel chemotherapeutic agents, such as the proteasome-inhibitor bortezomib (BTZ) or the antiangiogenetic and immunomodulator drugs thalidomide and its derivative lenalidomide, have significantly increased the complete response (CR) rate before and after Allogenic Stem Cell Transplantation (ASCT) with a positive impact on progression-free sur...

Interactions of Bone Marrow Stromal Cells with Native and RGD Surface Modified Acellular Bone Matrix: A Biocompatibility Study
This study investigated the biocompatibility of mesenchymal stem cells (MSCs) and native or surface modified ACM (RGD-ACM) scaffolds in the construction of tissue-engineered bone. Wistar rat bone marrow-derived MSCs were isolated by density gradient centrifugation for in vitro culture. MSCs were seeded on ACM with or without surface modification by RGD peptides to generate tissue-engineered bone for in vitro culture. Significantly higher adhesion of MSCs to RGD-ACM was observed compared with the native material. Detection of active alkaline phosphatase (ALP) indicated intercalation of this protein into the scaffold enhan...

Comparison of Mesenchymal Stem Cells (Osteoprogenitors) Harvested From Proximal Humerus and Distal Femur During Arthroscopic Surgery
Conclusions: Arthroscopic aspiration of bone marrow from the proximal humerus and distal femur is a reproducible technique and yields reliable concentrations of MSCs. The use of an intraoperative concentration method resulted in consistent amounts of MSCs in all clinically relevant age groups without a significant drop of the number of isolated MSCs.Clinical Relevance: Human MSCs derived from concentrated bone marrow aspirate are a promising biological addition that may have practical use in the future of soft tissue augmentation. Arthroscopic techniques for bone marrow aspiration that do not require an additional surgical...

Clinical Advances in Bone Regeneration.
Abstract Understanding of the biology of bone regeneration has been increasing rapidly, with greater appreciation for the importance of biochemical aspects as well as the mechanical requirements for bone to heal. There are a number of situations where there is difficulty in bone healing such as fracture non-union; or growth such as osteogenesis imperfecta; or a requirement for surplus bone to reconstruct defects such as following surgery for tumour excision or limb lengthening. There is a greater understanding of the complex interplay between osteoblasts and osteoclasts, and the chemical mediators that that provid...

A review of techniques for gene therapy in bone healing.
Abstract Gene therapy has been used successfully in several areas of medicine as a technique to either alter defective genes or as method to enable delivery of therapeutic proteins. Despite advances in surgical and pharmaceutical interventions for diseases of bone regeneration and healing, results in certain patient groups remain sub-optimal. With this considered, gene therapy is currently being investigated as a means of facilitating healing and improving outcomes. Two broad techniques which are currently utilised by research teams are discussed in this review; ex vivo and in vivo. The underlying principle is simi...

Preclinical and Clinical Studies on the Use of Stem Cells for Bone Repair: A Systematic Review.
Abstract The management of extensive bone defects in the setting of fracture repair, non-union and revision arthroplasty are challenging problems. The supply of harvestable autologous bone graft is limited, with an associated morbidity, and therefore a need exists for a better solution in large defects. The use of stem cells is an evolving field of research, with different potential applications, ranging from simple injection of cells to tissue engineering using osteogenic cells seeded onto a scaffold. This systematic review aims to collate the published preclinical and clinical studies investigating the potentia...

Current Strategies of Tissue Engineering in Talus Chondral Defects.
Abstract Due to the nature of articular cartilage of being poorly vascularized the capabilities of self repair are limited. Mesenchymal stem cells transplantation is a modern technique which has been developed after the high success rates obtained by microfracturing and drilling techniques which promote the release of growth factors and the infiltration of bone marrow derived cells in the lesion. In order to increase the concentration of bone marrow derived cells appropriate devices, the scaffolds, are necessary. These three dimensional constructs mimic the physiological ambient of chondrogenesis. The race for new ...

A systematic review on preclinical and clinical studies on the use of scaffolds for bone repair in skeletal defects.
Conclusions: There is a lot of pre clinical evidence that the use of scaffold combined with mesenchymal stem cells enhances osteogenesis when treating bone defects. There is limited clinical evidence at this early stage that scaffolds can be used safely and effectively in tissue engineered grafts to repair bone defects with no RCTs as yet having been conducted. The limited clinical series reported have however produced promising results. PMID: 23317473 [PubMed - as supplied by publisher]

Cytological, immunocytochemical, ultrastructural and growth characterization of the rainbow trout liver cell line RTL-W1.
Abstract Despite its wide use in toxicology, a detailed characterization of RTL-W1 cell line lagged behind leaving ambiguities about its cell origin. We aimed to better characterize the line regarding cell phenotype and tumorigenic state. We studied RTL-W1 cells in monolayers and in (4-22-week-old) aggregates considering: (a) morphology (light and electron microscopy); (b) immunophenotype using AE1/AE3, vimentin, Cam5.2, CK7 and CK19 and e-cadherin antibodies and (c) growth behavior. RTL-W1 organelle content is constituted basically by mitochondria and abundant free ribosomes, with no (cytochemically) detectable pe...

Targeting Role of Glioma Stem Cells for Gliobastoma Multiforme.
Abstract Glioblastoma multiforme (GBM) represents the most common and lethal malignant primary brain tumor. Despite vigorous basic and clinical studies over the past decades, the prognosis of patients with GBM has remained dismal. The fundamental problem with these malignancies is due to tumor cells' highly infiltrative nature, precluding a complete surgical resection, and a productive or acquired resistance to cytotoxic therapy. Recent studies demonstrated that GBMs exhibited remarkable cellular heterogeneity and hierarchy containing self-renewing glioma stem cells (GSCs). The malignant growth of GBM can be propag...

Embryonic Stem Cells Or Induced Pluripotent Stem Cells? A DNA Integrity Perspective.
Abstract Induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) are two types of pluripotent stem cells that hold great promise for biomedical research and medical applications. iPSCs were initially favorably compared to ESCs. This view was first based on ethical arguments (the generation of iPSCs does not require the destruction of an embryo) and on immunological reasons (it is easier to derive patient HLA-matched iPSCs than ESCs). However, several reports suggest that iPSCs might be characterized by higher occurrence of epigenetic and genetic aberrations than ESCs as a consequence of the reprogram...

Light chain amyloidosis 2012: a new era
Summary AL amyloidosis patients with multi‐organ and particularly cardiac involvement have historically been considered to have a bad prognosis. The introduction of autologous stem cell transplantation was associated with unacceptable toxicity in high‐risk patients, but responding patients have prolonged overall survival. Toxicities can be decreased by careful patient selection, but this reduces the applicability of this treatment modality to a limited number of patients. Efforts are therefore needed to design novel more effective regimens, with the use of new medications, such as thalidomide, lenalidomide and bortezom...

MLL‐rearranged acute lymphoblastic leukaemia stem cell interactions with bone marrow stroma promote survival and therapeutic resistance that can be overcome with CXCR4 antagonism
Summary Infants with MLL‐rearranged (MLL‐R) acute lymphoblastic leukaemia (ALL) have a dismal prognosis. While most patients achieve remission, approximately half of patients recur with a short latency to relapse. This suggests that chemotherapy‐resistant leukaemia stem cells (LSCs) survive and can recapitulate the leukaemia. We hypothesized that interactions between LSCs and the bone marrow microenvironment mediate survival and chemotherapy resistance in MLL‐R ALL. Using primary samples of infant MLL‐R ALL, we studied the influence of bone marrow stroma on apoptosis, proliferation, and cytotoxicity induced by th...

Feather regeneration as a model for organogenesis
In the process of organogenesis, different cell types form organized tissues and tissues are integrated into an organ. Most organs form in the developmental stage, but new organs can also form in physiological states or following injuries during adulthood. Feathers are a good model to study post‐natal organogenesis because they regenerate episodically under physiological conditions and in response to injuries such as plucking. Epidermal stem cells in the collar can respond to activation signals. Dermal papilla located at the follicle base controls the regenerative process. Adhesion molecules (e.g., neural cell adhesion m...

Repigmentation of Poliosis After Epithelial Grafting for Vitiligo
ConclusionRe‐coloring of poliosis with vitiligo is possible but was unexpected because of the difference in mechanism and signaling required between hair bulb melanization and the surface skin. One likely mechanism to explain this change is that melanocyte stem cells are stimulated and migrate to supply hair bulbs with new mature melanocytes. Epithelial grafting of vitiligo with poliosis in hairy areas should be a treatment of choice when white hair tufts cause cosmetic disfigurement.

Researchers in Japan have for the first time shown it is possible to make cancer-specific immune system cells from induced pluripotent stem cells (iPSCs). Their work brings closer the day when therapies use cloned versions of patients' own cells to boost their immune system's natural ability to kill cancer cells. The researchers, from the RIKEN Research Centre for Allergy and Immunology in Yokohama, describe how they created cancer-specific killer T lymphocytes from iPSCs, in a paper published online on 3 January in the journal Cell Stem Cell...
