Nephron generation in kidney cortices through injection of pretreated mesenchymal stem cell-differentiated tubular epithelial cells.

In this study adding collecting duct cells (CDCs) and their CM, we demonstrate the suppressive actions of CDC-CM against VECs and TECs, in addition to stimulative cross-talks between VECs and TECs, during the above changes. Furthermore, CDC-CM, similar to TEC-CM, caused differentiation of MSCs into TECs. Thus, we injected CDC-CM-induced MSC-differentiated TECs into rat kidney cortices. The pretreatment of cells in 3-dimensional culture using a small amount of gel complex before implantation triggered the generation of much more nephron-like structures, compared to the implantation of non-pretreated cells. Our method of injecting pretreated TECs into kidney cortices might have applications for repairing dysfunctional kidney tissue. PMID: 31420163 [PubMed - as supplied by publisher]
