Tcf7l1s cell autonomously repress anterior endothelial cell development. ((A)and (B)) Control and Tcf7l1 deficient Tg(kdrl:EGFP) embryos. Tcf7l1 deficient Tg(kdrl:EGFP) embryos have a dramatic loss of the ACEs at 28 hpf. (C) Schematic of the cell transplantation strategy used for assessing cell autonomy. Red indicates injection with the rhodamine-dextran lineage tracer. (D) Representative image of cranial ECs from donor WT/Tg(kdrl:EGFP) cells transplanted into a WT host. View is fronto-lateral. (E) Representative image of cranial ECs from donor Tcf7l1 deficient/Tg(kdrl:EGFP) cells transplanted into a WT host. View is frontal. (F) Frequency of ACEs found in transplantation experiments. Asterisk indicates a statistically significant difference compared to control transplant experiments.
