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.
采用间接免疫荧光法研究了胚胎鸡脊髓腹角中神经肽K-免疫反应性（NPK-LI）的可能出现情况。结果显示，在孵化第5天至孵化期间，外侧运动柱细胞中短暂出现了NPK-LI。此后它们消失，在腹角中NPK-LI仅保留在纤维中。根据NPK在发育过程中可能的营养作用对结果进行了讨论。
