Self-renewal of hepatoblasts under chemically defined conditions by reiterative growth factor and chemical screening


ABSTRACT: Throught an reiterative growth factor and chemical screening, we defined a small molecule and growth factor cocktail, including EGF, glycogen synthase kinase 3 inhibitor (CHIR99021), transforming growth factor β receptor inhibitor (e.g. E-616452), lysophosphatidic acid and sphingosine 1-phosphate, that can sustain long-term self-renewal of murine hepatoblasts under chemically defined conditions. The expandable hepatoblasts (eHBs) by this small molecule and growth factor cocktail expressed a set of genes typical of liver progenitor cells and liver development, and retained the ability to respond to liver developmental cues and produce functional hepatocytes and form bile duct-like structures. Moreover, both early- and late-passage eHBs demonstrated a similar transcriptome profile. Microarray analysis also confirmed that the gene expression of cultured cells resembled hepatoblasts.
