Figure 1From: Differential expression dynamics of Growth differentiation factor9 (GDF9) and Bone morphogenetic factor15 (BMP15) mRNA transcripts during in vitro maturation of buffalo (Bubalus bubalis) cumulus–oocyte complexes Morphological changes of buffalo COCs during IVM. COCs morphology observed under the microscope for: (A) 0 h, (B) 6 h, (C) 12 h, (D) 24 h. During 12 h (C) and 24 h (D) of maturation, the outermost layers of the cumulus cells become round and glistening.Back to article page
