Comparing the Effects of Human and Fetal Bovine Serum on Mesenchymal Stem Cells Under Oxidative Stress
Objectives: Stem cells are undifferentiated cells capable of creating different types of cell in the body. Stem cell proliferation often is performed in the culture medium supplemented with Fetal Bovine Serum (FBS). Unknown compounds in the FBS, risk of contamination and disease transmission encourages the researches toward finding an alternative to FBS. Several factors are involved in the Mesenchymal Stem Cells (MSCs) precocious death in the transplanted tissue environment. Oxidative Stress (OS) is one of the main causes of stem cell apoptosis in the initial days after transplantation. The aim of this study was to evaluate the effect of Human Serum (HS) on the viability and oxidative related enzymes in human Adipose tissue-Derived Stem Cells (ADSCs) under oxidative stress in comparison with FBS.
Materials & Methods: Human serum were obtained from blood of a healthy donor persons, in respective intervals during few days. The ADSCs were isolated from lipolysis operation samples and their cuture media were supplemented with FBS or HS and different concentrations of H2O2 as the oxidative agent.
Results: The results showed that cell proliferation and viability of ADSCs under oxidative stress condition was significantly higher in the culture medium supplemented with HS in comparison with FBS supplemented medium (P<0.05).
Conclusion: This study showed that FBS could be replaced by HS in MSC culture medium with improved effects on cell proliferation and oxidative related enzyme activity under oxidative Stress condition.
