Semaphorin 3A
- Alteration of Nrp1 signaling at different stages of olfactory neuron maturation promotes glomerular shifts along distinct axes in the olfactory bulb
Summary: During olfactory bulb development in mice, different axonal targeting outcomes are dependent on the timing of Nrp1/Sema3A signaling.
- Endothelial cell-derived semaphorin 3A inhibits filopodia formation by blood vascular tip cells
Summary: Endothelial cells produce Sema3A, a known axon repellent, that exerts repelling functions on VEGF-A-induced tip cell filopodia during angiogenesis in mice.
