ABSTRACT
Evolution has crafted vertebrates with two exquisitely elaborate systems each specialized to perform their unique and vital functions: the nervous and vascular systems. These two systems are wired in a stereotyped branching pattern to ensure that all tissues receive proper neural control and adequate blood supply. However, in contrast to our advanced understanding of neural circuit assembly, how the nervous system becomes closely aligned with the vascular system during development and ultimately establishes functional neurovascular units is still poorly understood. Previous studies have suggested that neurovascular congruency is established through a “one-patterns-the other” model, in which neural or vascular architecture precedes and instructs the other system to form using its template. However, recent study in complex tissue such as whisker follicle shows that neurovascular congruency does not follow the previous model but rather is established via another mechanism in which nerves and vessels are patterned independently. Given the diversity of neurovascular structures in different tissues, understanding the basic rules of neurovascular patterning will provide new insight into molecular mechanisms of how neuronal development is established in parallel with vascular patterning during normal development as well as in disease settings.
