Abstract Chang's medium [with and without human serum (HS)] was compared with T6 medium [with and without bovine serum albumin (BSA)] for in vitro fertilization (IVF) and development of two-cell mouse embryos to the blastocyst stage. Chang's medium without any supplementation gave significantly better fertilization rates (83.3%) than Chang's with 10% HS (76.4%) or T6 and BSA (76.6%) (P 〈0.01). In a separate experiment 87.7% of the two-cell mouse embryos developed to the blastocyst stage in Chang's medium supplemented with 10% HS, 76.6% of the embryos developed to the blastocyst stage and 17.2% stopped development after the morula stage. After 72 hr in vitro hatched trophoblast and inner-cell-mass cells from 26.5 and 30.8% of the embryos grown in Chang's medium (with and without HS) attached to the plastic culture dishes and grew to form a mixed monolayer of epithelioid and fibroblastic cells. Chang's medium can thus be successfully used for IVF and growth of mammalian embryos. Further, inner cell mass and trophoblast cell lines could be established for various reproductive studies using this medium.
