ABSTRACT
【Objective】 To compare the effects of human albumin products from different domestic manufacturers on human stem cell culture. 【MethodsHuman CD34+ cells were cultured by supplementing human albumin from different manufacturers to serum-free medium, and the expansion ratios of cells within 15 days were counted. Post translational modifications of human albumin products were studied by LC-MS. 【Results】 Supplementing plasma-derived human albumin(pd-alb) to serum-free medium, the expansion ratios of cells could reach up to 20.6±5.7, while the recombinant human albumin(rhAlb) resulted in no significant expansion within 15 days. LC-MS showed significant differences in post-translational modifications from different human albumin products. 【Conclusion】 Different human albumin products showed significantly different effects in the expansion of stem cells due to different sources, processes and stabilizers. Pd-alb products were better for stem cell culture than rhAlb products. There are significant differences between pd-albs and rhAlbs in post-translational modification, but whether these differences are related to stem cell expansion remains to be studied.
