Culture medium (ASF-301) of tHUE-2 cell, human endothelial cell line, and culture medium of these cells (conditioned medium : CM) which affect embryonic development of in vivo fertilized 1-cell embryos of mouse were examined. Two-cell stage block of mouse embryos was overicomed in ASF-301 and CM without EDTA, which usually added in basic medium (modified Whitten Medium: MWM, control) to overcome the 2-cell stage block. The developmental rates of embryos to the blastocyst stage were significantly increased in MWM containing 12.5% of growth factors added to ASF-301 (10mg/ $\ell$ transferrin, 1mg/$\ell$ insulin, 0.01mg/$\ell$ EGF) than those of 100% addition and control, 78.0% vs 20.8 and 52.3%, respectively (P<0.05), but the growth factors was not affected the hatching rate of blastocyst. Using ASF-301 or CM which was not treated, embryonic development into the blastocyst and hatched blastocyst stages were not affected. However, proportions of embryonic development into the blastocyst and hatched blastocyst stages were significantly higher in dilution (ASF-301 1:10; CM 1:3~1:6) than those in control (P,0.05). In ASF-301 dialyzed M.W.<10000 dialysis membrane, the developmental rate upto the hatched blastocyst stage was significantly increased, compared to ASF-301 which was not dialyzed (P<0.05), and hatching rate of blastocyst of these group was singnificantly increased than those in MWM (P<0.05). Compared to CM which was not dialyzed, however, in dialyzed CM was significantly decreased, compared to untreated CM (P<0.05), especially any hatched blastocyst was not appeared. As a result of these experiments indicated that a kind or porper treatment such as a dilution of complex synthetic cell culture medium and conditioned medium, and that a optimal concentration of growth factors are usuful for embryo cultrue in vitro.
