Abstract

Abstract: Objective:to analyzevarious growth factor (GF) content in umbilical cord derived mesenchymal stem cell (UC-MSC) culture waste at harvest.Methods: We cultured UC- MSCs in complete medium, and collected the medium waste at harvests.  We noted the time of harvests, and measured the concentrations of EGF, VEGF, NGF and Pl GF in the various medium wastes using ELISA method. We grouped GF concentrations according to various culture lengthsat harvest, and calculated themean values and standard deviations of the various GF. We compareddescriptively the GF concentrations at various culture lengths at harvests to conclude which condition yielded the overall highest GF concentration.Results: EGF, VEGF and PlGF concentrations were highest at harvest day-3, whileNGF concentration was the highest at harvest-day-5, respectively. Therefore, overall highest concentration of most GF was at harvest day 3.Conclusion:UC-MSC culture waste at harvest day-3 containedEGF, VEGF, NGF and PlGF, which might be used in regenerative medicine.

Abstract

Objective: Bone marrow mesenchymal stem cells are promising in cell therapy but the low frequency of this subpopulation necessitates their in vitro expansion and cryopreservation prior to clinical use. The aim of this study was to analyze the passage effect on the aging profile of previously successive cryopreserved bone marrow mesenchymal stem cells.  Methods: The samples of this in-vitro observational analytic study (April - September 2016) were iliac crest bone marrow mesenchymal stem cells that were cryopreserved in passage one and a second group was cryopreserved after being subcultured. It was obtained from UPT TK Sel Punca RSCM-FKUI. Samples were analyzed for each passage in terms of cell size, viability, population doubling time (PDT), and percentage of senescent cells by ANOVA test and independent t-test for the inter-cryopreservation group.Results: The remarkable manifestation of senescence appeared at passage six in both cryopreserved groups, but tend to appear earlier in the twice cryopreservation group. The senescent positive cell size became bigger along with the increasing number of passage. There were significant differences in PDT, 30% confluent cell size, viability, in passage six between the two cryopreservation groups (p<0.001, p<0.001, p=0.022), respectively, but no significant difference in percentage of senescent cells (p= 0.052). The cells became senescent in P6 in both groups (P=0.000).Conclusion: The onset of senescence of bone marrow mesenchymal stem cells was in passage six, while PDT, cell size and viability differ significantly due to successive cryopreservation.
