Protocol used to study secretion of proteins and prostaglandins by endometrium from the cow, ewe, mare, bitch and other species. The technique is also useful for culture of peri-implantation conceptuses and placental tissues for metabolic labelling studies and to obtain conceptus secretory proteins for biological studies.The medium used is called Pig MEM, which is a modified minimum essential medium supplemented with non-essential amino acids, vitamins, insulin and additional glucose. - [Read Culture of Endometrial Explants and Peri-implantation Conceptuses to Monitor Synthesis and Secretion]
Isolation of postimplantation-stage embryos allows one to study normal development as well as genetic mutations which cause post-implantation defects. This protocol describes a method for isolating early primitive-streak-stage embryos. - [Read Isolating Postimplantation Embryos: Early Primitive-Streak-Stage Protocol]
Isolation of postimplantation-stage embryos allows one to study normal development as well as genetic mutations that cause post-implantation defects. This protocol describes a method for isolating prestreak-stage embryos (~5.5 days post coitum [dpc]). - [Read Isolating Postimplantation Embryos: Prestreak-Stage Protocol]
Protocol describes a method for removal of mouse ovaries in combination with the administration of progesterone, which causes the arrest of blastocyst development. This procedure is performed during the afternoon of the third day of pregnancy to ensure that the morulae have moved sufficiently into the oviducts and will be less likely to be damaged during the ovariectomy. - [Read Ovariectomy for Induction of Blastocyst Implantation Delay Protocol]
This protocol describes a method for visualizing early embryo implantation sites using Chicago Sky Blue 6B dye. Once implantation and interimplantation sites are identified and separated, they can be used for cellular, biochemical, and molecular biology analyses. - [Read Visualizing Early Embryo Implantation Sites by Dye Injection Protocol]
