    摘要: A novel parenchymal hepatocyte growth factor originating in a human or animal liver, having an estimated molecular weight according to nonreductive SDS-PAGE of about 63,000 to about 69,000, an estimated molecular weight according to reductive SDS-PAGE of about 32,000 to about 36,000 and an estimated molecular weight according to gel filtration of about 60 to about 70 Kd; and having an activity of effecting the growth of parenchymal hepatocyte has been obtained from the hemihepatectomized tissue. Furthermore, a gene coding for the above substance has been obtained from the mRNA of the above tissue and it has thus become possible to mass-produce the above substance.
