| Outline of Final Research Achievements |
The method of hepatic stellate cell (HSC) isolation from young and old mouse liver with low-speed centrifugation was established. Gene expression of liver regeneration related genes including HGF and TGFβ. The expression of HGF mRNA in old HSC was significantly lower than that in young HSC. Conditioned medium from old HSC promoted less liver regeneration compared with that from young HSC. For analysis of the difference in unfolded protein response (UPR) of them, HSC was stimulated with stress inducer. The expression of Bip (GRP78) which is sensor of UPR in old HSC was similar with young HSC.
