(Submitter supplied) Ex vivo expansion of Bone Marrow Stromal Cells (BMSC) is required to obtain clinical dose for cellular therapy, and different labs use different confluence in their practice, however, the impacts of 100% confluence on the biological properties of BMSC remain controversial. In this study, we detected the changes occurred to BMSCs when they reached 100% confluence, including viability, population doubling time (PDT), apoptosis, colony formation, immunosuppression, proteins in the culture supernatant, and surface markers; we also performed gene expression profiling and microRNA profiling on 50%, 80% and 100% confluent BMSCs. more...

(Submitter supplied) Background: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with 20% fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. Methods: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis. more...

(Submitter supplied) Bone marrow stromal cells (BMSCs) can be expanded by serial passage, but expansion is limited by cell senescence.  The nature of changes associated with BMSC serial passages was assessed. Transcriptome analysis of 10 early and 15 late passage samples from 5 subjects revealed 2193 differentially expressed genes; those highly expressed in early passage cells were overrepresented in skeletal system development, embryonic morphogenesis, tube morphogenesis, etc, while those highly expressed in the late passage BMSCs were overrepresented in nucleosome assembly; chromatin assembly, DNA packaging, etc. more...

(Submitter supplied) Abstract Background: Bone marrow stromal cells (BMSCs) are being used for immune modulatory, anti-inflammatory and tissue engineering applications, but the properties responsible for these effects are not completely understood. Human BMSCs were characterized to identify factors that might be responsible for their clinical effects and biomarkers for assessing their quality. Methods: Early passage BMSCs prepared from marrow aspirates of 4 healthy subjects were compared to 3 human embryonic stem cell (hESC) samples, CD34+ cells from 3 healthy subjects and 3 fibroblast cell lines. more...

(Submitter supplied) Background: Studies suggested that mesenchymal stem cells (MSCs) have intrinsic neurogenic potential and can be differentiated into neural stem cell/ neural progenitor cells (NPCs) under specific microenvironment. Manipulation of growth factors is one of the popular method to achieve trans-lineage differentiation of MSCs. Synergistic effect of epidermal growth factor (EGF) and fibroblast growth factor 2 (bFGF) have been widely identified as basic requirement for neural differentiation to take place. more...

(Submitter supplied) Objective: Craniofacial bone defects caused by injuries and congenital diseases are a formidable challenge to clinicians. Research has shown promise in using bone marrow mesenchymal stem cells (BM-MSCs) from limb bones for craniofacial bone regeneration; yet little is known about the potential of BM-MSCs from craniofacial bones. This study compared BM-MSCs isolated from limb and craniofacial bones in pigs, a preclinical model closely resembling humans. more...

(Submitter supplied) Background Bone marrow stromal cells (BMSCs) are a heterogeneous population that participates in wound healing, immune modulation and tissue regeneration. Next generation sequencing was used to analyze transcripts from single BMSCs in order to better characterize BMSC subpopulations. Methods Cryopreserved passage 2 BMSCs from one healthy subject were cultured through passage 10. The transcriptomes of bulk BMSCs from designated passages were analyzed with microarrays and RNA sequencing (RNA-Seq). more...

(Submitter supplied) Donor variation is a prominent critical issue limiting applicability of cell-based therapies. We asked whether reference protocols for pre-clinical bone marrow stromal cell (BMSC) propagation using human platelet lysate (hPL) to replace xenogeneic fetal bovine serum (FBS) might also reduce donor variability for osteo-chondral regeneration. We therefore investigated the impact of donor variability, hPL- vs FBS driven propagation and exhaustive proliferation, on BMSC epigenome, transcriptome, phenotype, coagulation risk and osteochondral regenerative function. more...

(Submitter supplied) Bone marrow derived stromal cells (BMSCs) are a multipotent population that supports angiogenesis, wound healing, immunomodulation and plays an active role in the hematopoietic niche. On the other hand, they are also involved in the nurturing of bone marrow tumors and metastasis, showing a pro-tumorigenic behavior. BMSCs secrete a wide range of cytokines, growth factors and matrix proteins that are likely responsible for many of these effects. more...
