title: Autotransplantation of lymph node fragments. Structure and function of regenerated tissue.
abstract: In pigs slices of autologous lymph nodes were implanted in the subcutaneous fat, under the muscular fascia or under the kidney capsule to study the regeneration of autotransplanted lymph node tissue. The regenerated nodules consisted of all the normal compartments found in lymph nodes and there was evidence that afferent lymphatics reached these nodules. Superficial inguinal lymph nodes regenerated more often and with a better structure than mesenteric lymph nodes. The sites under the kidney capsule and the fascia of muscles were found to be a less stimulating microenvironment for regeneration than the subcutaneous tissue. Regeneration of transplanted lymph node tissue was observed in pigs which had been operated on as young piglets or as adults. The regeneration of autotransplanted lymph node tissue might be a useful model for draining lymphedema, especially from the extremities.
