Expression pattern of Gata2a in the lens of Nile tilapia at different developmental stages. (A–C’) Expression of Gata2a was detected in the fiber cell mass of the lens from larvae at 5 dpf. (D–F’) Gata2a expression was detected in the nucleus of primary and secondary (anterior and posterior elongating) lens fiber cells, most prominently in the primary lens fiber cell near the equatorial zone where differentiation first initiates, from juvenile at 30 dpf. (G–I’) Gata2a was consistently detected in the nuclei of primary fiber cells along the equatorial zone of the lens at 90 dpf. (C’,F’) was the higher magnification fluorescent micrograph of the boxed region shown in (C,F), respectively. dpf: day post fertilization. ep: epithelial cell; plf: primary lens fiber cell; slf: secondary lens fiber cell.
