Larger Image Figure 1. Temporal and spatial expression pattern of XRFC. (A) XRFC is expressed maternally and throughout the stages examined (St.0 to St.32) as detected by RT-PCR. T, negative control without reverse transcriptase in the RT reaction. (B) Expression of XRFC at the indicated stages revealed by in situ hybridization. (B) The maternal XRFC expression is detected at the animal pole at 2-cell stage. (C) At stage 18, XFRC is expressed at the anterior neural plate and its border. (D) At the late neurula stages, the expression of XRFC is detected in the prospective eye and forming branchial arches. (F) At tailbud stage, XRFC is strongly expressed in the branchial arches, eyes, head mesenchyme and the somites. Br, branchial arch. Image published in: Li J et al. (2011) Li et al.
