Fusimotor neurons, group Ia afferents and muscle spindles are absent in mutant mice lacking the gene for neurotrophin-3 (NT3). To partition the effect of Ia afferent or spindle absence from that of NT3 deprivation on fusimotor neuron development, we…
In the injured brain, the behavior of neural stem/progenitor cells (NSCs) is regulated by multiple converging factors encountered in the niche, which is composed of several neural and non-neural cell types. Signals emanating from the host influence…
