Studies with organotypic culture of sympathetic ganglia and spinal cord revealed that substance P at concentrations of 10(-5) to 10(-12) M and 10(-5) to 10(-14) M exerts a marked growth-stimulating effect on sympathetic ganglia and spinal cord, respectively. In the presence of substance P, the intensity of sympathetic ganglion growth exceeds control values 3.0-4.8 times. The growth zone size of spinal cord explants increases under these conditions 2.0-5.2-fold. A feasible physiological significance of regulatory peptides in the growth and regeneration of nervous tissue as well as the role of noci-antinociceptive systems in histogenesis and regeneration are discussed.
