VEGFC, its receptor FLT4, and transcriptional effector PROX1 control formation of the lymphatic system but how is unclear. Here, the authors show that the transcription factor hematopoietically expressed homeobox (HHEX) regulates VEGFC, FLT4 and PROX1 in fish and mammals during angiogenic sprouting and lymphatic formation.
