In the present study, total lipid content and content of triglycerides, phospholipids and cholesterol were determined in pig blastocysts cultured in medium without protein, supplemented with bovine serum albumin (BSA), with fetal calf serum (FCS), vitamin E or phenazine ethosulfate (PES). In comparison to blastocysts cultured in NCSU-23 with BSA, we observed a decrease of the total lipid content in PES-treated embryos. Triglyceride content in FCS-, vitamin E- and PES-treated embryos as well as in blastocysts cultured without protein was 81.9%, 70.2%, 57.2% and 74.8% of that found in the blastocysts cultured in NCSU-23 with BSA, respectively. Nevertheless the content of phospholipids remained unchanged. This decrease of triglyceride content in the porcine blastocyst after in vitro culture may be explained by altered lipid metabolism in embryos.

UI MeSH Term Description Entries
D010619 Phenazines
D001755 Blastocyst A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552 Swine Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).

D014810 Vitamin E A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.

D018613 Microscopy, Confocal A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.
