RESUMEN
The ultrastructural characteristics of the mouse mammary adenocarcinoma cell line (MA782/5S-8102) have been studied by transmission electron microscope. The results show that the cells were irregular in the shape, with abundant microvilli on cell surface. The nucleus was abnormal in shape with the nuclear membrane sunk or swollen, the nucleus/cytoplasmic ratio (N/C) was high. There were many free ribosomes, abundant mitochondrias, dilated rough endoplasmic reticulum in the cytoplasm. Golgi apparatus, lysosomes and lipid droplets were present. Moreover, many cytoplasmic type-A particles and a few immatural type-B particles at the surface of the cell were observed.
