zebrafish
fish model of vertebrate embryological development. Embryos ar translucent and large number of known (and manufactured) mutants. (More? Other Embryos - Zebrafish)
ZIFT
acronym for Zygote Intra Fallopian Transfer, a procedure in which eggs are collected from a woman's ovaries and fertilized outside her body. A laparoscope is then used to assist in placing the resulting zygote (fertilized egg) into the woman's uterine (fallopian) tube through small incisions in her abdomen. (More? Week 1 Notes - In Vitro Fertilization)
ZP1
acronym for Zona Pellucida Binding Protein, a glycoprotein found in zona pellucida surrounding the egg. (More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1)
ZP2
acronym for Zona Pellucida Binding Protein 2, a glycoprotein found in zona pellucida surrounding the egg. Before fertilization ZP2 binds spermatozoa. After fertilization ZP2 is proteolytically cleaved as an initial block to polyspermy. (More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1)
ZP3
acronym for Zona Pellucida Binding Protein 3, a glycoprotein found in zona pellucida surrounding the egg required for initial zona matrix formation and during fertilization for species-specific sperm binding. Now thought to exist in 2 isoforms ZP3A and ZP3B (a second polymorphic allele). (More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1)
ZPBP1
acronym for Zona Pellucida Binding Protein 1 A spermatozoa protein found located on the acrosome surface. (More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein 1)
(Latin, zona pellucida = transparent zone) A specialized extracellular matrix surrounds the developing oocyte (egg, ovum) within the ovary and follwing ovulation. It consists of three types of glycoproteins ZP1, ZP2 and ZP3 which have different roles in fertilization. Following fertilization, the zona pellucida also surrounds the blastocyst during the first week of development, from which it "hatches". The zona pellucida has a role in fertilization, sperm binding, preventing polyspermy, blastocyst development and preventing premature implantation (ectopic pregnancy). (More? Week 1 - Fertilization | Week 1 - Oogenesis | zona pellucida binding protein)
zona pellucida binding protein 1
(ZPBP1) A spermatozoa protein found located on the acrosome surface which has a role during spermiogenesis (acrosome compaction, Sertoli-spermatid junctions) and also binds the zona pellucida during fertilization. (More? Week 1 - Fertilization | Week 1 - Fertilization)
an animal disease that can be transmitted to humans. This can be through contact with animals (pets, farm animals, wildlife) or their products (milk, meat, waste). (More? Toxoplasmosis | Q Fever)
The first diploid cell that forms following fertilization by fusion of haploid oocyte (egg) and spermatozoa (sperm) resulting in the combination of their separate genomes. (More? Week 1 Notes)
zygote intrafallopian transfer
(ZIFT) A procedure in which eggs are collected from a woman's ovaries and fertilized outside her body. A laparoscope is then used to assist in placing the resulting zygote (fertilized egg) into the woman's uterine (fallopian) tube through small incisions in her abdomen. (More?
