| Outline of Final Research Achievements |
To examine the relationship between direct reprogramming of fibroblasts into induced hepatocyte-like (iHep) cells and cellular proliferation, we sequentially analyzed the early stage of fibroblast conversion into iHep cells using live-cell imaging, immunofluorescence staining, and quantitative polymerase chain reaction analyses. Our data demonstrated that the conversion into iHep cells began within 48 hours after introduction of the transgenes into fibroblasts, and the number of iHep cells increased gradually as the culture progressed. The rapid cell-fate conversion of fibroblasts into iHep cells and stable expansion of iHep cells will be useful in the future cell transplantation therapy and screening of drugs for patients with liver diseases.
