The objective of this study was to determine whether bovine embryos become more resistant to deleterious effects of maternal heat stress as early embryonic development progresses. Superovulated, lactating Holstein cows were bred by AI and assigned to be heat stressed on d 1, 3, 5, or 7 of pregnancy (d 0 =day of estrus) or not heat stressed (control). Embryos were retrieved from the uterus on d ...
Lysophosphatidic acid (LPA) is a known cell signaling lipid mediator in reproductive tissues. In the cow, LPA is involved in luteal and early pregnancy maintenance. Here, we evaluated the presence and role of LPA in bovine early embryonic development. In relevant aspects, bovine embryos reflect more closely the scenario occurring in human embryos than the mouse model. Transcription of mRNA and ...
among the female sexual hormones, the estrogen and progesterone are of significant importance. these hormones are prescribed for the treatment of certain female genital system disorders as well as used in the synthesis of contraceptive drugs. it has been shown that administration of the above hor mones during early pregnancy may produce abortion in early gestational days. in the present investi...
Pluripotency genes are implicated in mouse embryonic genome activation (EGA) and pluripotent lineage specification. Moreover, their expression levels have been correlated with embryonic term development. In bovine, however, little information is available about dynamics of pluripotency genes during these processes. In this study, we charted quantitative and/or qualitative spatio-temporal expres...
myostatin is a growth factor belonging to the tgfß superfamily. tgfß growth factors are active in the regulation of embryonic development and in tissue homeostasis in adults. myostatin is a growth factor controlling proliferation of myoblasts in embryonic development. mutations in coding sequences of the bovine myostatin (gdf8) gene lead to muscle hyperplasia suggesting its inhibitory function ...
