 ETV2ER71 has emerged as a key player in endothelial cell development and vascular regeneration. Studies have shown that it can be used to reprogram non-endothelial cells into endothelial cells, which could potentially be used to treat vascular diseases. Future research should focus on developing strategies to harness the full potential of ETV2ER71 in order to develop new therapies for vascular diseases.
