• tissues
  • Our knowledge of how bird embryos may process maternal steroids had been limited to several studies that investigated the ability of early embryonic tissues to metabolize steroids in vitro , where it was demonstrated that, by 48 h of incubation, chicken blastoderms are capable of metabolizing several steroids [ 14 - 16 ].

  • produces
  • At oviposition, the separation of maternal and embryonic endocrine environments produces a discrete initial maternal steroid signal after which there is no further endocrine interaction between mother and embryo. (royalsocietypublishing.org)
