| Popis: | The presence of α-fetoprotein (AFP) and serum albumin (SA) has been described within developing brain cells of mammals and chicken. In order to avoid the influence of the choroid plexuses in the transport, via cerebrospinal fluid, of these proteins to brain cells, we studied the presence of AFP and SA within chicken sensory ganglion cells during ontogeny using the indirect immunoperoxidase technique. Our results show that before day 9 of egg incubation, both AFP and SA can be detected within the trigeminal and spinal ganglia cells. Henceforth, the labeling for AFP starts decreasing in the spinal ganglia but not in the trigeminal ganglion. The labeling for SA remains constant in both structures. Differences between AFP and SA staining in the spinal ganglia are maximal on day 11 of incubation, when AFP is no longer detected. It is concluded that at this time, the uptake of AFP by spinal ganglia cells is switched-off while SA is still taken up. As the blood concentration of both proteins is similar at this time, the finding reported here gives support to the advanced hypothesis suggesting the presence of specific receptors for AFP and/or SA in embryonic neural cells. |
