Distribution of vasoactive intestinal polypeptide-, calcitonin gene-related peptide-, somatostatin- and neurofilament-immunoreactivities in sympathetic ganglia of human fetuses and premature neonates.
The distribution patterns of vasoactive intestinal polypeptide (VIP), calcitonin gene-related peptide (CGRP), somatostatin (SOM) and neurofilament (NF) immunoreactivities (IR) were studied in the stellate ganglia of human fetuses and neonates at 24-26 weeks gestation. Sizeable populations with some quantitative variations of VIP-, CGRP- and SOM immunoreactive nerve cells were detected in all ganglia studied. In marked contrast, neurofilament expression was down-regulated. The upregulation of VIP, CGRP and SOM expression suggested their inductor effect on growth and differentiation neurons as well as on the development of their neurotransmitter properties. The main neuropeptides-inducing factor of sympathetic ganglia in human prenatal ontogenesis may be considered as a relative hypoxia.
