Neurotrophins and basic fibroblast growth factor are ligands of tyrosine kinase receptors, though they bind to different tyrosine kinase receptor classes. Neurotrophins bind to receptor tyrosine kinase class VII, Trk receptor family, while basic fibr

In this work we analyze the effects of vitrification on the ultrastructure and developmental ability of bovine oocytes matured in the presence of 9-cis-retinoic acid (RA). Bovine cumulus oocyte com...

The objective of this study was to determine the effect of a sustained propylene glycol administration to recipients of frozen/thawed in vivo derived bovine embryos. Heifers were treated with oral propylene glycol for the last 20 days before embryo t

The isomer 9-cis of retinoic acid (9-cis-RA) exerts a beneficial effect on bovine in vitro development when added to in vitro maturation (IVM) culture. In the present work, 9-cis-RA 5 nM was found to be stimulatory as opposed to 500 nM (toxic). Cumul

This study evaluated the effect of two commercial serum replacements (Ultroser G and CPSR-3 on in vitro bovine embryo culture. In Experiment 1, zygotes were cultured in SOF+Ultroser G (2, 4 and 6%), SOF+CPSR-3 (2, 4 and 6%), and SOF+5% FCS (control).

It is known that the ketone bodies acetoacetate and D-beta-hydroxybutyrate can be metabolized by the early bovine embryo for in vitro development. In the present work, we report experiments leading to the culture of bovine embryos in the absence of s

In contrast to the embryos derived from live animals, the embryos produced in vitro undergo increased damage and reduced survival after cryopreservation, particularly when produced with serum. In medium containing serum, retinoic acid increases cell

Retinoids regulate development and differentiation of the bovine blastocyst in vitro, although the underlying mechanisms remain to be clarified. A challenge in reproductive biotechnology is the identification of pathways that regulate early embryonic

Bovine embryonic stem cells are of potentially big value in transgenic research and studies of lineage commitment and development. Nevertheless, key aspects of the establishment of bovine embryonic stem cells such as the identification of specific pl

The aim of this study was to examine the effects of co-culture with Vero cells during the in vitro maturation (IVM) and three culture media, B2+5% fetal calf serum (FCS) on Vero cells, synthetic oviduct fluid (SOF)+5% FCS, and SOF+20gL −1 bovine se
