[Distribution of alpha-fetoprotein and albumin in paraffin sections of cells of Zaidel's ascitic hepatoma].

The alpha-fetoprotein (AFP) and albumin localization were studied in the cells of rat Zaidel's ascitic hepatoma. It was shown in the paraffine sections of the hepatoma cells fixed by mixture of 96 degrees ethanol with 1% glacial acetic acid that 9.3% of hepatoma cells contained AFP and 0.6% of the cells--serum albumin. Small quantities of the tumour cells had both of these proteins simultaneously. There was no definite regularity in the distribution of the AFP and albumin-containing cells in the tumour islands.
