Figure 5From: Onset of meiosis in the chicken embryo; evidence of a role for retinoic acidMeiosis in female chicken embryonic gonads in vitro . Day 10.5 embryonic gonads were explanted and grown in the absence or presence of serum (DMEM+ 10% FCS, 2% chick serum). After six days in culture, meiosis occurred normally in the developing cortex, as assessed by SCP3 immunofluorescence (red) in GCNA+ germ cells (green).Back to article page
