(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) 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) Recent years have witnessed the introduction of ex vivo expanded dermal fibroblasts for several cell therapy and tissue-engineering applications, including the treatment of facial scars and burns, representing a promising cell type for regenerative medicine. We tested different in-house produced human platelet lysate (HPL) solutions against fetal bovine serum as supplements for in vitro fibroblast expansion by comparing cell yield, molecular marker expression, extracellular matrix (ECM) generation, genomic stability and global gene expression. 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...

(Submitter supplied) Purpose: The population of muscle-derived stem cells called MuStem cells is presented as promising candidate for cell-based therapy of muscle diseases. To validate if this agent can be really presented as therapeutic product and so to be eligible to a future clinical use, it is now required to demonstrate beforehand an efficacy with cells prepared in compliance with good manufacturing practices (GMPs). more...

(Submitter supplied) Heterogeneous populations of human bone marrow-derived stromal cells (BMSC) are among the most frequently tested cellular therapeutics for treating degenerative and immune disorders, which occur predominantly in the aging population. Currently, it is unclear whether advanced donor age and commonly associated comorbidities affect the properties of ex vivo-expanded BMSCs. Thus, we stratified cells from adult and elderly donors from our biobank (n = 10 and n = 13, mean age 38 and 72 years, respectively) and compared their phenotypic and functional performance, using multiple assays typically employed as minimal criteria for defining multipotent mesenchymal stromal cells (MSCs).We found that BMSCs from both cohorts meet the standard criteria for MSC, exhibiting similar morphology, growth kinetics, gene expression profiles, and pro-angiogenic and immunosuppressive potential and the capacity to differentiate toward adipogenic, chondrogenic, and osteogenic lineages.We found no substantial differences between cells from the adult and elderly cohorts. more...
