摘要
Calretinin immunostaining was performed on chick lumbosacral dorsal root ganglia during embryonic development. Calretinin-immunopositive neurons were first observed at around the 9th day of incubation. Quantitative evaluation revealed a close correlation between the number of immunopositive cells and the duration of incubation. Morphometric measurements disclosed that calretinin-immunoreactive cells belong in the large or intermediate categories of dorsal root ganglion neurons. It was concluded that the appearance of calretinin immunopositivity in spinal ganglion cells during development may be associated with both the morphological and functional maturation of this particular population of primary sensory neurons.
