Ultrastructural characteristics of non-matured and in vitro matured oocytes collected from pre-pubertal and adult domestic cat ovaries
(2009-07-01)
The present study describes the ultrastructural characteristics of cat oocytes before maturation and after 12- and 24-h in vitro maturation (IVM). Oocytes were recovered from pre-pubertal and adult queen ovaries after ...
Simulated physiological oocyte maturation has side effects on bovine oocytes and embryos
(2019-03-15)
Purpose: Oocyte maturation is a complex process involving nuclear and cytoplasmic modulations, during which oocytes acquire their ability to become fertilized and support embryonic development. The oocyte is apparently ...
Ultrastructural characteristics of non-matured and In vitro matured oocytes collected from pre-pubertal and adult domestic cat ovaries
(Berlin, 2009)
The present study describes the ultrastructural characteristics of cat oocytes before maturation and after 12- and 24-h in vitro maturation (IVM). Oocytes were recovered from pre-pubertal and adult queen ovaries after ...

Ultrastructural study of the ovary of the sugarcane spittlebug Mahanarva fimbriolata (Hemiptera)
(Elsevier B.V., 2006-01-01)
The present study describes the ultrastructure of meroistic telotrophic ovaries of the sugarcane spittlebug Mahanarva fimbriolata. In this type of ovary, nurse cells, oogonia, and prefollicular tissue are located at the ...

Preliminary analyses of cell death pathways activated by excess cholesterol in mouse oocytes.
(2017)
High density lipoprotein (HDL) cholesterol is taken up by liver Scavenger Receptor Class B type I (SR-BI), and subsequently metabolized in bile. SR-BI deficient (SR-BI KO) mice have large, cholesterol-rich HDL. Females are ...
Ovarian Reverse Cholesterol Transport: Involvement of Follicular Fluid HDL in Oocyte Cholesterol Homeostasis.
(2016)
Reverse cholesterol transport (RCT) is key for cellular cholesterol homeostasis, involving cholesterol efflux from cells to circulating high density lipoproteins (HDL) via ABC transporters followed by HDL cholesterol uptake ...
