| Abstract |
Immunohistochemical analysis revealed the temporal and spatial expression pattern of the amyloid protein precursor (APP) during the development of the mouse embryo. APP was first detected at day 9.5 of gestation in motor neurons of the hind brain and the spinal cord. APP proteins were also evident in cells of the floor plate, and in neurons of the cranial, dorsal root, and sympathetic ganglia shortly after their formation. Except for floor plate cells, APP expression was restricted to differentiated neurons. Comparison with the expression of microtubule-associated protein 2 (MAP-2), a marker for neurodifferentiation, showed that APP is expressed on a subset of differentiated neurons. APP can also serve as an early marker for the developing nuclei of the hind brain. The onset of APP expression in neurons appeared to be correlated with axonal outgrowth, whereas later expression of APP may be associated with functional specialization in the developing nervous system. |
