“…All these tests were negative. Additionally, the parameters of hUCB-MSC vitality, and biological characteristics were tested to meet with International Society for Cellular Therapy standards 19 and documented in test reports for each batch of cell product, including morphology, cell count (5× 10 7 cell/mL, range 90% to 120%, and 1 mL/vial), viability rate (≥90%), cell surface markers, colony-forming ability, differential capacity, and so on. Regarding the cell surface markers, it was found that CD90, CD73, CD105, and CD29 were higher than 95%, and CD45, CD34, CD79a/ CD19, CD14, and HLA-DR were less than 2%.…”
