Fig. 1, S2 Angptls-MO morphants had no defect in primitive hematopoiesis.
Top panels: somite matched embryos are scored by double staining with myod (orange, staining somite boundaries) and scl (purple, for early blood and vascular progenitor cells in the anterior (A) and posterior (P) bilateral stripes of the lateral plate mesoderm (LPM), black arrowheads, 10–12 ss). Middle and bottom panels: gata1-positive proerythroblast formation was also unaffected in these morphants in the posterior LPM (black arrowheads, 10–12 ss) and intermediate cell mass (black arrows, 24hpf). Scale bars: 200 µm (for top and middle panels); 50 µm (for bottom panels).
