Isolated rat hepatocytes release an acidic glycoprotein(s) that can selectively promote the growth of transformed cells. This factor has a molecular weight of 60 000-70 000 D. Liver microsomal and cytosol fractions contain two species of stimulatory activity-44 000 and 3 500 D. Mitochondrial and nuclear fractions contain only the lower molecular weight factor.
