Allotransplantation of pituitary cells to rat testicle.
Fifty-three transplantations of pituitary tissue (intact and minced with scissors) under the tunica albuginea testis were carried out. In both series pituitary cells retained viability for up to 6 months. Transplantation of cell suspension was not accompanied by the formation of necrotic zone in the transplant; the adjacent testicular tubules and the entire testicular structure remained unchanged, while transplantation of large fragments of the pituitary tissue impaired of spermatogenesis in the adjacent testicular tubules, although most of them remained unchanged. Hence, cell suspension is preferable for transplantation of pituitary tissue into the testicle.
