Faktor rasta hepatocita (HGF/SF) je morfogeni faktor koji utiče na parakrini ćelijski rast i motilitet. Njega izlučuju mezenhimalne ćelije. On prvenstveno deluje na epitelne i endotelne ćelije, ali i na hematopoietske progenitorne ćelije. Pokazano je da ima značajnu ulogu u embrionskom razvoju organa, u regeneraciji organa kod odraslih osoba i zarastanju rana.^[1]

Faktor rasta hepatocita reguliše ćelijski rast, ćelijsku mobilnost i morfogenezu putem aktiviranja signalne kaskade tirozinskih kinaza nakon vezivanja za proto-onkogeni c-Met receptor. Faktor rasta hepatocita izlučen iz mezenhimalnih stem ćelija dejstvuje kao multi-funkcionalni citokin. Njegova sposobnost da stimuliše mitogenezu i ćelijsku motilnost daje mu centralnu ulogu u angiogenezi, tumorogenezi, i regeneraciji tkiva. On se izlučuje kao neaktivni polipeptid, koga presecaju serinske proteaze u 69-kDa alfa-lanac i 34-kDa beta-lanac. Disulfidna veza između alfa i beta lanaca proizvodi aktivni, heterodimerni molekul. Ovaj protein pripada plazminogen potfamiliji S1 peptidaza, ali nema primetnu proteaznu aktivnost. Alternativno splajsovanje ovog gene proizvodi višestruke transkriptne varijante koje kodiraju razne izoforme.^[2]
