Steroidogenesis in rabbit preimplantation embryos.
Rabbit preimplantation embryos were flushed from the reproductive tract at 24 hr (1- to 2-cell stage), 48 hr (morula), 72 hr (morula), 96 hr (blastocyst), 120 hr (blastocyst), and 144 hr (blastocyst) post coitum. At 168 hr (early postimplantation period), gestation sacs were excised, frozen, and sectioned in a cryostat. Delta5-3beta-Hydroxysteroid dehydrogenase [3(or 17)beta-hydroxysteroid:NAD(...
متن کاملDevelopment of Rabbit Preimplantation Embryos under Thermal Stress in Vitro
The aim of our study was to examine the influence of short-term (6h) hyperthermia (41.5 °C and 42.5 °C) on the developmental capacity of preimplantation rabbit embryos in vitro. Rabbit embryos were isolated from superovulated and inseminated rabbit females after slaughter by flushing from oviducts of 19 hpc. The embryos were cultured in k-DMEM medium with the addition of 10 % fetal calf serum. ...

متن کاملHuman chorionic gonadotropin secreted by preimplantation embryos cultured in vitro.
Human oocytes were collected by laparoscopy and fertilized and cultured in vitro. Human chorionic gonadotropin was detected in the medium surrounding two embryos cultured for more than 7 days after fertilization.
متن کاملPreimplantation development of embryos in labrador retrievers.
Preimplantation development of canine embryos is not well understood. To understand the timing of preattachment embryogenesis relative to the luteinizing hormone (LH) surge, early embryonic development was examined in Labrador Retrievers after artificial insemination. The embryos migrated from the oviduct to the uterus beginning on day 11 after the LH surge. This transport must be completed wit...
