Abstract
REINERI, Pablo S. et al. Gene expression of growth factor BMP15, GDF9, FGF2 and their receptors in bovine follicular cells. Rev.MVZ Cordoba [online]. 2018, vol.23, n.3, pp.6778-6787. ISSN 0122-0268. https://doi.org/10.21897/rmvz.1367.
Objective.
Evaluate mRNA expression of GDF9, BMP15, FGF2 and their main receptors, transforming growth factor beta receptor 1 (TGFβ-R1), bone morphogenetic protein receptor, type IB (BMPR-IB) and fibroblast growth factor receptor 2 (FGFR2) in bovine follicular cells.
Materials and methods.
Total RNA was isolated from pooled samples of oocytes (OOs), cumulus cells (CCs) of cumulus oocyte complexes (COCs) and follicular cell pellets (PCs) of 70 ovaries obtained from 96 beef heifers, collected at a local abattoir. The expression pattern of growth factors and their receptors in follicular bovine cells was evaluated by reverse transcriptase polymerase chain reaction (RT-PCR).
Results.
The mRNA transcripts encoding GDF9, BMP15, FGF2, TGFβ-R1, BMPR-IB and FGFR2 genes were detected, by RT-PCR, in all studied cells. This is the first time that the expression of TGFβ-R1 and BMPR-IB receptors is reported in bovine oocytes.
Conclusions.
The presence of growth factors and receptor transcripts in the studied cells indicate that these factors could act as paracrine and autocrine regulators of folliculogenesis.
