Fig 2. Apoptosis detected by TUNEL assay.
Loss of FGFR2-induced apoptosis in mouse lens (l) (arrowheads in B, D, and F), but not in cornea epithelium (CE) (arrows in A-D). In E12.5 WT and Fgfr2 CKO eyes, TUNEL-positive cells were found in the corneal mesenchymal cells and in the hyaloid cells of the primary vitreous. (LE, lens epithelium; C, cornea)
