Nonintegrating Direct Conversion Using mRNA into Hepatocyte-Like Cells

Figure 2

Generation of R-iHeps using mRNA from MEFs. (a) Scheme of generation of R-iHeps. mRNAs of modified HNF4α and Foxa3 were transfected with lipofectamine on day 0 and 3. MEFs: mouse embryonic fibroblasts; R-iHeps: RNA induced hepatocyte-like cells. (b) The morphology of directly converted R-iHeps by mRNA. On day 12, R-iHeps were shown and grown. Insets: higher magnification of the boxed areas. Scale bars: 100 um.
