Recently, we reported a chemical approach to generate pluripotent stem cells from mouse fibroblasts. However, whether chemically induced pluripotent stem cells (CiPSCs) can be derived from other cell types remains to be demonstrated. Here, using lineage tracing, we first verify the generation of CiPSCs from fibroblasts. Next, we demonstrate that neural stem cells (NSCs) from the ectoderm and small intestinal epithelial cells (IECs) from the endoderm can be chemically reprogrammed into pluripotent stem cells. CiPSCs derived from NSCs and IECs resemble mouse embryonic stem cells in proliferation rate, global gene expression profile, epigenetic status, self-renewal and differentiation capacity, and germline transmission competency. Interestingly, the pluripotency gene Sall4 is expressed at the initial stage in the chemical reprogramming process from different cell types, and the same core small molecules are required for the reprogramming, suggesting conservation in the molecular mechanism underlying chemical reprogramming from these diverse cell types. Our analysis also shows that the use of these small molecules should be fine-tuned to meet the requirement of reprogramming from different cell types. Together, these findings demonstrate that full chemical reprogramming approach can be applied in cells of different tissue origins and suggest that chemical reprogramming is a promising strategy with the potential to be extended to more initial types.
