RESUMEN

In order to investigate the influence of biomatrix on Sertoli cell morphology and on the phospholipids content, these cells were isolated from tests of 15-day old Wistar rats and plated ontoplastic coated with extracellular matrix extracted froma seminiferous tubules, here denoted biomatix. When the Sertoli cells were cultured on biomatrix they did not from a monolayer until day 7 of culture, while cells plated onto plastic did so 48 h after plating. On day 5 of culture. Sertoli cells were incubated for 48 h with 5 µCi/ml 32P. There was no difference in 32P incorporation into lipids of cells plated onto biomatrix or plastic. However, there was a larger amount of phospholipid phosphate in cells plated onto biomatrix than onto plastic. When the phospholipds were analyzed by bidimensional thin-layer chromatography, no diferences were detected in their distribution; however, there was a significant decrease in the percentage of sphingomyelin in cells plated onto biomatrix when compared to plastic. These results showed that the cells cultured on biomatrix change their phospholipids content, but not their distribution. The importance of a small reduction in sphingomyelin content remains to be investigated
