- Resumo: During the development, embryos are under the effects of different cytokines, growth factors and other regulatory molecules present in the female tract. Particularly interesting is the presence of TNF-? at physiological doses in these sites and, at high concentrations in inflammatory processes. Studies focusing the embryonic susceptibility to the TNF-? have been done in different species, but most of these were directed to the blastocyst stage. In this study, mice embryos were collected at 4-8 cells phase, cultivated for 24 h in the presence or absence of different concentrations of TNF-? and, morphologically analyzed. In the presence of TNF-? the embryos had less blastomeres, modified nuclear morphology and most of them were blocked in the morula phase when compared with the control group. Great part of the TNF-?-treated blocked embryos was positive for caspase-8 and reactive for anexina-V indicating the entrance in apoptosis process. Similar but less frequent responses were also found in the control group. The use of impermeable fluorescent dyes and Hoechst was also important for characterizing the nuclear integrity of plasma membrane and nuclear morphological alterations in the different experimental groups. These findings suggest that TNF-? may act on the cleavage phase by blocking the course of embryo development, leading to cellular death by apoptosis, adding new information on the embryos susceptibility in the phase of pre-implantation
