Perfused rat liver and rat hemicorpus preparations release a factor that promotes the growth of SV3T3 cells. This material (TFGF) has a molecular weight of approx. 35 000 D and is sensitive to proteolytic enzymes. TFGF does not promote the multiplication of sparse 3T3 cells or initiate DNA synthesis in confluent 3T3 cells.
