Essential role of stem cell factor signaling in primary sensory neuron development.

Abstract excerpt

Here we show that stem cell factor (SCF) signaling through its receptor, c-kit, is essential for the development of c-kit-expressing small- and medium-diameter primary sensory neurons. We used the W mouse, which is c-kit deficient and has a perinatal lethal phenotype due to a naturally occurring point mutation in the c-kit gene. In c-kit-null newborn mice, 52.5% of substance P immunoreactive and 31.4% of...
