Thalidomide administered to the marmoset ( Callithrix jacchus ) will produce a pattern of deformities similar to those found in man. In the cervical and lumbar regions of the thalidomide malformed marmoset fetus, the spinal cord and dorsal root ganglia are smaller than those of the control. The reduction in size of the D.R.G.'s is due to a marked reduction in the number of neurons. Drugs which influence the function of cholinergic nerves in the chick and rabbit embryo interfere with development. Thalidomide produced peripheral neuropathy in adults by interference with the function of the cholinergic nerves. Thus it appears that thalidomide malformations are due in part, to an interference with numbers of, and probably the functions of, the cholinergic nerves in the embryo. It would appear that cholinergic nerves have a possible morphogenetic and trophic influence in embryogenesis.
