Figure 1. p27Xic1 [cdknx ] is expressed at late tail bud stages in the pronephros by in situ analysis.Whole mount in situ hybridization was carried out with a DIG-labeled anti-sense RNA probe for p27Xic1. prior to and including stage 25, p27Xic1 expression in the presumptive pronephros is not detected by in situ hybridiza- tion.At stage 27 p27Xic1 expression is clearly evident in the dorso-anterior region of the presumptive pronephros (white arrow). Pronephric staining is confirmed in transverse sections at stage 27 through the anterior pronephros anlagen (white arrow).At stage 30 a similar pattern of p27Xic1 expression to that seen at stage 27 is observed in the dorsal anterior pronephros anlagen. By stage 32 p27Xic1 expression is concentrated in the nephrostomes and proximal tubules. No pronephric expression of p27Xic1 is detected by in situ hybridization at stage 38. (som, somites; nt, neural tube; ba, branchial arches; pr, pronephros; lh, lymph heart; ma, migrating muscle anlagen). |
