چکیده انگلیسی
The nonobese diabetic (NOD) mouse strain is a predominant animal model of type 1 diabetes. However, this mouse strain is considered to be non-permissive for embryonic stem cell (ESC) derivation using conventional methods. We examined small molecule inhibition of glycogen synthase kinase 3 (GSK3) to block spontaneous cell differentiation and promote pluripotency persistence. Here we show a single pharmacological GSK3 inhibitor, 6-bromoindirubin-3â²-oxime (BIO), in combination with leukemia inhibition factor (LIF), promoted generation of stable NOD ESC lines at >80% efficiency. Significantly, expansion of the established NOD ESC lines no longer required treatment with BIO. These NOD ESC lines contributed to chimeric mice and transmitted to germline progeny that spontaneously developed diabetes. By contrast, 5-aza-2â²-deoxycytidine (AZA), a small molecule inhibitor of DNA methylation, and trichostatin A (TSA) and valproic acid (VPA), small molecule inhibitors of histone deacetylase, could not promote generation of NOD ESCs by epigenetic remodeling. These combined findings provide strategic insights for imposing pluripotency in cells isolated from a non-permissive strain.
