Maturational changes in motility, acrosomal proteolytic activity, and penetrability of the inner perivitelline layer of fowl sperm, during their passage through the male genital tract.
The IGG members also expressed concern that injected chemicals may not enter the embryo, but instead might partition to the yolk or get trapped in the perivitelline space.
Perivitelline fliud's most abundant perivitelline, namely, PcPV2 and PcOvo, are complex particles exclusively synthesized in the AG-CG and massively accumulated in the eggs, where they account for nearly 70% of egg proteins (Dreon et al., 2002, 2003; Sun et al., 2012).
The inner mucous matrix functions as a medium for the oviducal gland jelly, and is essential for chorion expansion and the formation of the perivitelline space around the ovum (Ikeda et al.
Polar body and metaphase plate were removed with the aid of micromanipulators, and then only one Wharton jelly's cell or skin fibroblast between third and tenth passages was injected into the perivitelline space.
In the assessment of the quality of oocytes one can carry out scoring of cumulus-oocyte complex (COC), ZP, perivitelline space, PB, vacuolizations, etc.
On a broad scale, identifications traditionally have been based on morphological characteristics, including egg shape and diameter; number, size, and position of oil globules; width of the perivitelline space; nature of the egg yolk and chorion surface; and embryonic pigmentation.
For morphometric characterization of dry fertilized eggs, perivitelline space (PS) and mouth opening and total length of newly hatched larvae were measured for 100 specimens with an ocular micrometer adapted on a stereomicroscope.
Subsequently, NO- and/or [H.sub.2]S-posttranslationally modified proteins lead to MPF/MAPK-orchestrated meiotic maturation reinitiation (equal to GVBD, germinal vesicle breakdown) and completion (with extruded polar body and small particles visible in perivitelline space).
Finally, oocytes were considered penetrated when their zona pellucida contained at least one sperm in perivitelline or cytoplasm space (29,30).
The onset of oocyte activation are vitellus ink, release discharge and migrate into the perivitelline space.
Oocytes with intact cell membrane and clear perivitelline space were selected for future use.
