OBJECTIVE Effect of hepatocyte transplantation on long-term survival after fulminant hepatic failure was studied in rats. METHODS Sprague-Dawley rats were divided into: Group I (n = 65), intrasplenic hepatocyte transplantation followed by fulminant hepatic failure; Group II (n = 31), intrasplenic saline injection followed by fulminant hepatic failure; Group III (n = 24), 70% hepatectomy. For survival, 35 animals of Group I and 19 of Group II were observed. Six animals of each group were euthanized on postoperative days 1, 7, 14 and 28 to study biochemistry, liver growth rate, labeling index of proliferating cell nuclear antigen, hepatocyte growth factor and transforming growth factor. RESULTS Postoperatively, Group I had a better survival than Group II. Group I also showed a better biochemical profile on day 1 as compared with Group II, and on day 28, Group I had a normal profile. On day 28, the remnant liver in Group I reached 97% of the original liver weight. Group I had a better proliferating cell nuclear antigen labeling index than Group II on day 1 and exceeded Group III on day 14. On day 1, Group I had lower levels of hepatocyte growth factor and transforming growth factor than Group II while hepatocyte growth factor on days 7, 14 and 28 showed no difference between Group I and Group III. CONCLUSIONS Hepatocyte transplantation has achieved a long-term survival and improved the liver regeneration in rats with fulminant hepatic failure.

D016212 Transforming Growth Factor beta A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.

D053773 Transforming Growth Factor beta1 A subtype of transforming growth factor beta that is synthesized by a wide variety of cells. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta 1 and TGF-beta1 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor. Defects in the gene that encodes TGF-beta1 are the cause of CAMURATI-ENGELMANN SYNDROME.

D018809 Proliferating Cell Nuclear Antigen Nuclear antigen with a role in DNA synthesis, DNA repair, and cell cycle progression. PCNA is required for the coordinated synthesis of both leading and lagging strands at the replication fork during DNA replication. PCNA expression correlates with the proliferation activity of several malignant and non-malignant cell types. Antigen, Proliferating Cell Nuclear,PCNA
