Origins and molecular mechanisms underlying renal vascular development.

Kidneys play a crucial role in maintaining homeostasis within the body, and this function is intricately linked to the vascular structures within them. For vascular cells within the kidney to mature and perform their functions effectively, it is imperative that there is a meticulous and well-coordinated spatial alignment between the nephrons and the intricate network of blood vessels within the organ. This spatial arrangement ensures efficient filtration of blood and regulation of the electrolyte balance, blood pressure, and fluid levels. Additionally, the kidneys play a vital role in the regulation of acid-base balance and the production of hormones involved in erythropoiesis and blood pressure regulation. Thus, the close interaction between the vascular system and the kidney's structural organization is essential for maintaining overall physiological balance and health. This article focuses on the vascular development of the kidneys, summarizing the current understanding of the origin and formation of the renal vasculature, and the crucial molecules involved. By elucidating the cellular and molecular mechanisms governing renal vascular development, this article aims to promote advancements in renal regenerative medicine and provide potential avenues for therapeutic interventions to address kidney disease.
