Figure 7From: Midkine-A functions upstream of Id2a to regulate cell cycle kinetics in the developing vertebrate retinaExpression of id2a at 28hpf. In situ hybridization of wholemount embryos at 28 hpf recapitulates the tissue-specific pattern of id2a expression (cf. Figure 3, Thisse et al., 2004). Scale bar equals 100 μm L, lens.Back to article page
