Although there were numerous free ribosomes, the granular endoplasmic reticulum was predominant, and bundles of intermediate filaments surrounded the nucleus.
In the cytoplasm of these cells was verified the presence of a rich quantity of granular endoplasmic reticulum very developed (Fig.
In the animals maintained in lack of light few fibroblasts were observed, which presented a scarce cytoplasm and few quantity of granular endoplasmic reticulum. Simoes et al., (1985) analyzed the ultra-structure of endometrium of rats during the estral cycle, reported that in the metaestrus and diestrus phases, the fibroblasts were more numerous comparing to other phases of cycle, these authors observed in these cells, the presence of several intra cytoplasmatic vesicles containing collagen fibrils, showing thus, a collagen absorption activity in these phases of cycle.
