[Histochemical, fluorescent autoradiographic study of paraganglion cells in the superior cervical ganglion of the newborn rat following maternal stress].
Catecholamine storing paraganglionic cells in the neonatal rat superior cervical ganglion were investigated after maternal stress exposure. Paraganglionic cells as fluorescence-microscopically identified were significantly increased in number when compared with controls. The autoradiographically recorded labelling index of these cells, however, was unaltered. Fluorescent cell clusters were apparently composed of different cell types. The results support the suggestion that the stress-dependent increase in the number of catecholamine storing cells is due to differentiation of premature cell forms rather than to enhanced mitotic activity.
