In Vitro Differentiation of Human Umbilical Cord Blood CD133+ Cells into Insulin Producing Cells in Co-Culture with Rat Pancreatic Mesenchymal Stem Cells
Journal Title: Cell Journal(Yakhteh) - Year 2015, Vol 17, Issue 2
Abstract
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.
