Figure 1. Broad expression of malectin in embryonic and adult X. laevis. (A) Analysis of embryos by whole mount in situ hybridization showing malectin expression in the anterior neuroectoderm (ne) and neural crest (nc) at stages 18 and 20 (A1, A2), and at later stages, e.g., 32, in the hatching gland (hg), retina (re), otic vesicle (ot), epibranchial placodes (eb), pronephros (pn), and the tail tip (tp); anterior (a); posterior (p). At stage 41 (A4), transcripts are detected in the liver (li), dorsal and ventral pancreas (dp and vp), branchial arches (ba), and the proctodeum (pd). (B) Analysis of embryonic expression of malectin by RT-PCR showing expression in the oocyte (stage VI) and continued expression throughout development, and the contrasting expression of protein disulfide isomerase, xPDIp, only from late tadpole stage 39 onward. Abbreviations: stage VI oocyte (VI); unfertilized egg (0) and fertilized egg (1). (C) The expression analysis in adult tissue by semiquantitative RT-PCR showing a broad distribution of malectin in comparison with xPDIp, which is detected in pancreas and stomach only. Additional abbreviations not defined in A: gall bladder (gb); heart (he); intestine (in); kidney (ki); lung (lu); muscle (mu); pancreas (pa); stomach (st).
