[Long-term transplantation of mature sensory neurons]

The spinal ganglia were transplanted into the mesocolon of adult cats for periods of from 1 day to 9 months. About 30% of differentiated sensory neurons survived during the longterm transplantation. The intensive regeneration of the sensory neurons processes was characteristic of the transplanted neurons. Total myelinization of the regenerating nerves occurred during the 3rd--5th month. Potential regeneration capacity of the differentiated neurons and possibly of their prolonged transplantation were revealed.
