Wnt signaling in zebrafish and stickleback replacement tooth germs. Black arrows mark replacement tooth germ epithelium, white arrows mark replacement tooth germ mesenchyme. awnt10a expression in a cap-stage zebrafish replacement tooth germ. bWnt10a expression in a bud-stage stickleback replacement tooth germ. Note concentrated expression in the distalmost epithelium (arrow). clef1 expression in a cap-stage zebrafish replacement tooth germ. dLef1 expression in a bud-stage stickleback replacement tooth germ. e, f TCF/Lef synthetic Wnt activity reporter is active in adult replacement tooth germs.
