Mutant ptpn11 Enhances the Proliferation of MYCN-Induced Hyperplastic Neuroblasts in the IRG

(A) Sagittal sections through the IRGs of control Dβh, ptpn11mut, MYCN, and MYCN;ptpn11mut transgenic fish at 5 wpf (dorsal up, anterior left). GFP, green; Hu, red; DAPI, blue; merge, combined green, red, and blue. Representative sections through the IRG of control Dβh or ptpn11mut fish contain 1-5 GFP+/Hu+ sympathetic neuroblasts (arrowheads). Hu+ cell numbers increase in MYCN and MYCN;ptpn11mut fish (brackets). Dotted lines indicate the head kidney (HK) boundary. Scale bar, 20 μm.

(B) Numbers of GFP+/Hu+ sympathetic neuroblasts in the IRG regions of control Dβh, ptpn11mut, MYCN, and MYCN;ptpn11mut transgenic fish at 5 wpf.

(C) Percentage of EdU+/Hu+ sympathetic neuroblasts in control Dβh, ptpn11mut, MYCN, and MYCN;ptpn11mut transgenic fish at 5 weeks. Mean values (horizontal bars) were compared by Welch t test (two-tailed).
