Notes:
It has become evident that certain growth factors are involved in the regulation of the initial bovine embryogenesis. In the present study, we examined by means of Northern blot and in situ hybridization, the expression and localization in the bovine oviduct of mRNAs encoding for platelet-derived growth factor (PDGF-B), basic fibroblast growth factor (bFGF), and insulin-like growth factor (IGF-I).Northern blot analysis on oviduct tissue demonstrated transcripts for PDGF-B and bFGF, but not IGF-I mRNAs. Two bands with estimated sizes of 5.0 and 1.5 kb were detected for PDGF-B and two bands with sizes of 7.5 and 4.9 kb for bFGF. In situ hybridization analysis demonstrated localization of PDGF-B mRNA in the lamina epithelialis and tunica muscularis of the oviduct whereas bFGF mRNA was detected in the lamina propria. It is concluded that the lamina epithelialis and lamina propria of the oviduct represent sites of synthesis of PDGF-B and bFGF mRNA, respectively. © 1995 wiley-Liss, Inc.
