[Some characteristics of the process of forming autophagocytic vacuoles in the hepatocytes of regenerating rat liver].

This work deals with the previously described process of cellular autophagocytosis in regenerating rat liver. The experimental data obtained indicate that the early appearance of acid phosphatase positive cytoplasmic vacuoles (with diameter more than 2 mu) occur only in a certain portion of the parenchymal cell population (nearly 30% of the total number of hepatocytes) and mainly in the central area of the hepatic lobule. It may be concluded that the observed reaction of the cell vacuolar apparatus concerns hepatocytes that undergo the entry into the mitotic cycle much later than does the main part (ca 60%) of cell population.
