عنوان انگلیسی In Vitro Differentiation of Human Umbilical Cord Blood CD133+Cells into Insulin Producing Cells in Co-Culture with Rat Pancreatic Mesenchymal Stem Cells
چکیده انگلیسی مقاله Objective
Pancreatic stroma plays an important role in the induction of pancreatic cells by the use of close range signaling. In this respect, we presume that pancreatic mesenchymal cells (PMCs) as a fundamental factor of the stromal niche may have an effective role in differentiation of umbilical cord blood cluster of differentiation 133+ (UCB-CD133+) cells into newly-formed β-cells in vitro.
Materials and Methods
This study is an experimental research. The UCB-CD133+cells were purified by magnetic activated cell sorting (MACS) and differentiated into insulin producing cells (IPCs) in co-culture, both directly and indirectly with rat PMCs. Immunocytochemistry and enzyme linked immune sorbent assay (ELISA) were used to determine expression and production of insulin and C-peptide at the protein level.
Results
Our results demonstrated that UCB-CD133+differentiated into IPCs. Cells in islet-like clusters with (out) co-cultured with rat pancreatic stromal cells produced insulin and C-peptide and released them into the culture medium at the end of the induction protocol. However they did not respond well to glucose challenges.
Conclusion
Rat PMCs possibly affect differentiation of UCB-CD133+cells into IPCs by increasing the number of immature β-cells.
