The expression of MMPs in the development of the fertilized egg has a very important role in cell configuration. Objective To evaluate the clinical, the effect of differentially expressed MMPs on serum and serum - free medium on the maturation of blastocysts. The expression patterns of MMPs in serum and serum-free medium were compared at 6 h, 18 h and at the blastocyst stage using real-time PCR, ELISA and immunofluorescence. The results showed that the expression of MMPs was increased in the embryos of the serum medium, as a result of analysis of MMPs and TIMPs, MMP-2 was expressed in the cytoplasm of embryos in the serum-free medium, And it was found to be higher in expression than MMP-9. The serum medium was different from the bloodless badge: overall, TIMPs showed a higher expression in the ovarian cells than cyanosis, and TIMP-3 was more pronounced. Development rate of blastocyst according to in vitro culture method was higher than that of serum - free medium (61.22% 60/98) and serum - free medium (48.28% 28/58). Analysis of the protein release locations of MMPs and TIMPs showed that MMPs and TIMPs are highly expressed in serum mediums, focusing on the inner cell mass. However, very low expression appeared in the tropoblast. On the other hand, serum - free medium showed different expression from serum medium and TIMPs expression was generally low.
Therefore, in the case of serum media, the expression of MMPs is highly expressed in the cytoplasm of the fertilized egg, increasing the reconstruction of cells.
