COMPOSITION FOR GROWTH MEDIA OF MAMMALS EARLY EMBRYO COMPRISING SECRETORY LEUKOCYTE PEPTIDASE INHIBITOR AND METHOD FOR CULTURING MAMMALS EARLY EMBRYO IN VITRO TO KEEP NORMAL DEVELOPMENTAL SPEED USING THE SAME

摘要

The present invention relates to a culture medium composition for mammalian early embryo growth including a secretory leukocyte peptidase inhibitor and an early embryo vitro culture method using the same for maintaining a normal generation speed and, more specifically, to a culture medium composition and a vitro culture method using the same, capable of promoting a generation speed to a similar speed to vivo culture and improving an implantation rate in comparison to existing embryos in vitro culture. According to the present invention, the secretory leukocyte peptidase inhibitor included in the culture medium composition is able to enable the generation of an embryo in vitro culture to progress similarly to in vivo culture and to increase the expression level of various generators, thereby improving the implantation rate and early embryo generation rate in comparison to embryos cultured through a conventional in vivo culture method. The present invention is able to be applied to clinics using sterile medical science or embryo differentiation.
