چکیده انگلیسی
The feasibility of transforming embryonic endoderm into different cell types is tightly controlled by mesodermal and septum transversumal signalings during early embryonic development. Here, an induction protocol tracing embryonic liver development was designed, in which, three growth factors, acid fibroblast growth factor, basic fibroblast growth factor and bone morphological protein-4 that secreted from pre-cardiac mesoderm and septum transversum mesenchyme, respectively, were employed to investigate their specific potency of modulating the mature hepatocyte proportion during the differentiation process. Results showed that hepatic differentiation took place spontaneously at a low level, however, supplements of the three growth factors gave rise to a significant up-regulation of mature hepatocytes. Bone morphological protein-4 highlighted the differentiation ratio to 40-55%, showing the most effective promotion, and also exhibited a synergistic effect with the other two fibroblast factors, whereas no similar phenomenon was observed between the other two factors, which was reported for the first time. Our study not only provides a high-performance system of embryonic stem cells differentiating into hepatocytes, which would supply a sufficient hepatic population for related studies, but also make it clear of the inductive effects of three important growth factors, which could support for further investigation on the mechanisms of mesodermal and septumal derived signalings that regulate hepatic differentiation.
