Huis group discovered a specific combination of three transcription factors consisting of GATA4, HNF1 and FOXA3, which converted p19 Arf/ mouse tail-tip fibroblasts to iHeps with a higher conversion efficiency ( Hnf1a and Foxa3 transduction was already sufficient to induce iHeps and addition of Gata4 enhanced the conversion efficiency ( Hnf1 and Foxa3 directly induced MEFs into hepatic stem cells which had the bipotential of differentiating into hepatocytes and cholangiocytes (Yu et al., 2013)
