Embryonic myeloid progenitors from PTPN11D61Y/+; VavCre+ embryos demonstrate GM-CSF growth hypersensitivity. A) E14.5 fetal liver mononuclear cells (n=7) or B) E9.5 yolk sac cells (n=8) were plated in methylcellulose colony forming assays and colonies were counted 7 days later. * p<0.05; ** p<0.001 by two-tailed Student’s t-test.
