Figure 1From: Temporal regulation of mRNAs for select bone morphogenetic proteins (BMP), BMP receptors and their associated SMAD proteins during bovine early embryonic development: effects of exogenous BMP2 on embryo developmental progressionTemporal changes in BMP2 (A), BMP10 (B), BMP3 (C) and BMP7 (D) mRNA abundance during oocyte maturation and early embryogenesis in vitro. Quantitative real time RT-PCR analysis was performed on samples of germinal vesicle (GV) and metaphase II (MII) stage oocytes and in vitro derived embryos collected at the pronuclear (PN), 2-cell (2C), 4-cell (4C), 8-cell (8C), 16-cell (16C), morula (MO) and blastocyst (BL) stages (n = 4 pools of 10 oocytes/embryos per pool). Data were normalized relative to abundance of endogenous control (RPS18) and are shown as mean ± SEM. Values with different superscripts across timepoints denote significant differences (P < 0.05).Back to article page
