Description:
Here, we develop a high-fidelity reprogramming strategy, by mimicking the natural cell-fate changing route, thus permitting the production of functionally competent human hepatocytes from another cell type. We first converted fibroblasts into plastic hepatic progenitor-like cells (hHPLCs) and chemically induced them into mature hepatocytes. The molecular identity of human induced hepatocytes (hiHeps) are suggested a terminally differentiated state, resembling primary human hepatocytes (PHHs). Functionally, hiHeps were competent to replace PHHs for equivalent drug-metabolizing activities, toxicity prediction and hepatitis B virus infection. Remarkably, the stably robust expansion of hHPLCs allowed large-scale generation of mature hepatocytes. Our results demonstrate the necessity of taking a reprogramming step for plastic progenitors for efficient cell-fate conversion. This strategy is promising for the generation of other mature human cell types.
