Localization of Gata2 in the lymphatic vasculature. E16.5 (A-B) and adult (C-D) skin immunostained with anti-CD31 (green), Prox1 (red), and Gata2 (cyan) antibodies. Arrows indicate Gata2 localization in lymphatic vascular valves; and arrowheads, Gata2-positive hematopoietic cells. Boxed regions in panels A and C are shown at higher magnification in panels B and D, respectively. Scale bars represent 30 μm (A,C), 10 μm (B), and 15 μm (D).
