Medication factor: Some medicines can affect embryonic development by placental barrier, such as, sleeping pill, antiallergic agent, diphenlhydantoin, adrenal cortical hormone and cyclophosphamide. 药物因素:有些药物能通过胎盘屏障影响胚胎发育,如安眠药、抗过敏药、苯妥英那、肾上腺皮质激素、环磷酸胺均可导致胎儿畸形。
Bovine oocytes can acquire their competence for fertilization and embryonic development in a serum free maturation medium during the in vitro maturation ( IVM), and this process can be enhanced by addition of follicle stimulating hormone, luteinizing hormone and epithelial growth factor to the maturation medium. 牛卵母细胞可在不含血清的成熟培养液中获得受精及胚胎发育能力,促卵泡素、促黄体素及上皮细胞生长因子均对这一过程具促进作用。
