Occurrence of neuropeptide K-like immunoreactivity in ventral horn cells of the chicken spinal cord during development.
The possible occurrence of NPK-LI in the ventral horns of the embryonic chicken spinal cord was investigated by means of the indirect immunofluorescence method. The results showed a transient appearance of NPK-LI in cells of the lateral motor column between day 5 of incubation and hatching. After this they disappeared and in the ventral horns NPK-LI remained only in fibers. The results are discussed in terms of a possible trophic action of NPK during development.
