[Biological activity of recombinant human hepatopoietin].

We examined the effects of rhHPO on the cell growth and DNA synthesis of both rat primarily cultured hepatocytes and hepatic carcinoma cell line in vitro by MTS and 3H-TdR in corporation methods. It was indicated that rhHPO is an important stimulating factor of regeneration, which may be developed as a potential drug for the treatment of severe hepatic diseases. We also found an inhibitory effect of rhHPO on the DNA synthesis of lung cancer cell lines GLC-82 in vitro, which might provide a valuable indicator for the study of its specificity and mechanisms.
