Development of foetal proteins

摘要: Abstract Prior to ovulation, the follicular fluid is known undergo depolymerization. After fertilisation, descending ovum must derive energy for cell division and growth from tubal contents, which are acted upon by its own enzymes those of spermatozoa present in tube. The mammalian can be supported vitro glucose or mannose, pyruvate lactate. It cannot fructose, galactose other sugars. During descent, endometrium has been conditioned receive ovum, glycogen stores have depolymerized glucose. At nidation, adult trophoblast invades responsible placentation. also furnishes initial protein developing embryo secretes hormones endometrial support. first autonomous fetuin, a glycoprotein contains no galactose. All available evidence shows that earliest hormone secreted contain Chorionic gonadotropin must, therefore, synthesized trophoblastic precursor tissue containing Waldenase enzymes. Fetuin anti fetuin sera prepared investigated immuno-electrophoresis.
