|Abstract:||Background aims: Mesenchymal stromal cell (MSC) transplantation holds great promise for use in medical therapies. Several key features of MSCs, including efficient cell growth, generation of sufficient cell numbers and safety, as determined by teratoma formation, make MSCs an ideal candidate for clinical use. However, MSCs derived under standard culture conditions, co-cultured with animal by-products, are inappropriate for therapy because of the risks of graft rejection and animal virus transmission to humans. Alternative serum sources have been sought for stem cell production. Methods: We demonstrate for the first time that human serum from umbilical cord blood (hUCS) is an effective co-culture reagent for MSC production from Wharton's jelly MSCs (WJMSCs). Ten umbilical cords were used to generate parallel cultures of WJMSC lines under medium supplemented with hUCS and embryonic stem cell-qualified fetal bovine serum. The WJMSC lines from each medium were analyzed and compared with regard to cell line derivation, proliferation ability and characteristic stability. Results: The phenotypic characteristics of WJMSC derived under either medium showed no differences. WJMSC lines derived under hUCS medium displayed comparable primary culture cell outgrowth, lineage differentiation capacity andcell recovery after cryopreservation compared with supplementation with embryonic stem cell-qualified fetal bovine serum medium. However, superior cell proliferation rates and retention of in vitro propagation (>22 passages) were observed inWJMSC cultures supplemented with hUCS. Additionally, more robust population doubling times were observed in hUCS-supplemented cultures. Conclusions: We conclude that hUCS is an efficient and effective serum source for animal product-free WJMSC line production and can generate MSC lines that may be appropriate for therapeutic use. © 2014 International Society for Cellular Therapy.|
