Developmental competence of different quality bovine oocytes retrieved through ovum pick-up following in vitro maturation and fertilization.
Karnāl, India. In Animal, Dec 2015
To analyze whether the developmental potential of the COCs bears a relation to morphological appearance, relative expression of a panel of genes associated with; (a) cumulus-oocyte interaction (Cx43, Cx37, GDF9 and BMP15), (b) fertilization (ZP2 and ZP3), (c) embryonic development (HSF1, ZAR1 and bFGF) and (d) apoptosis and survival (BAX, BID and BCL-XL, MCL-1, respectively) was studied at two stages: germinal vesicle (GV) stage and after in vitro maturation.
How the pterosaur got its wings.
Cambridge, United States. In Biol Rev Camb Philos Soc, Nov 2015
At limb-forming stages of pterosaur embryos, the zone of polarizing activity (ZPA) cells, from which the fourth finger eventually differentiates, could up-regulate, restrict, and prolong expression of 5'-located Homeobox D (Hoxd) genes (e.g.
Mutant ZP1 in familial infertility.
Xiamen, China. In N Engl J Med, 2014
The human zona pellucida is composed of four glycoproteins (ZP1, ZP2, ZP3, and ZP4) and has an important role in reproduction.
