(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...

(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) 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) 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...
