Two types of substance P-containing cells and their uneven distribution in the chicken retina: an immunohistochemical analysis with flat-mounts.
Substance P-like immunoreactivity (SPI) was investigated in the chicken retina by means of the indirect immunofluorescence method with flat-mounts. SPI cells were located mostly in the peripheral retinal regions, while in the central region, none or only a few cells were seen. Based upon their 3-dimensional profiles, SPI cells can be divided into two types: one type belongs to the stratified amacrine cells of the first sublayer and the other to those of the third to fifth sublayer.
