[State of the nerve cells of the cat spinal ganglia transplanted into the mesentery].
The survival of the mature differentiated neurons from the spinal ganglia under the conditions of autotransplantation into the colon mesentery of the cat was studied in chronic experiments. For two months, one-third of the neurons from the peripheral parts of the grafts survived and, as the normal ones, had a pseudounipolar form. However, their initial glomeruli had excessive overgrowth in the form of perivascular plexus, in its formation both the main axonal segment with its fine lateral branches and the finest offshoots from the neuronal bodies take part. These regenerating nerve fibres together with growth cones make terminals in the form of buttons, rings and loops. Such terminal structures in the capsular plexus around the neurons and in numerous Nageotte's cells present receptor terminals which are abundantly produced under the condition of the spinal ganglia transplantation.
