| Abstract: | Soluble cellular proteins from fetal rat hepatocytes, at 13-20 days of gestation were analyzed by 2-D gel electrophoresis and compared with protein patterns from adult hepatocytes and two hepatoma lines. The patterns of 13, 15 and 17 day fetal hepatocyte proteins were very similar. A number of proteins which were prominent in early fetal hepatocytes, were absent from the adult hepatocyte. Several proteins, which were also present in the adult pattern, appeared by day 17 of gestation. By day 20 of gestation, numerous proteins appeared and increased levels of a number of other proteins were observed. The adult hepatocyte protein pattern differed markedly from those of fetal hepatocytes. Many proteins present at low levels in fetal hepatocytes were increased in the adult, and at least thirty six new proteins appeared. The protein patterns of two hepatoma lines more closely resembled the early fetal rather than the adult hepatocyte pattern. |
