摘要: An analysis of hepatocellular proliferation in regenerating rat liver reveals a dependence kinetic parameters on the microvascular structure liver. Influx kinetics hepatocytes into DNA synthesis as well cell cycle phases vary different parts lobule between afferent and efferent vascular poles. Heterogeneity proliferative response size limitations compartments appear to be intimately related actual functional state individual cell. Modifications functions result variations activity. Phenobarbital-induced hypertrophy permissive action G1- S influx. Selective destruction subpopulations, by allyl formate, leads new determination residual change compartments. Maximum modulation is obtained hydroxyurea-induced synchronization after partial resection. During hydroxyurea treatment, shows pronounced cellular hypertrophy. After release from block, cells embark simultaneously. The synthesizing compartment comprises almost entire population. Heptotrophic factors might play part regulating or modifying function loss.
