  • Title: Regeneration of the seminiferous tubules after curettage of the testicular parenchyme in young rams.
    Author: Vrzgulová M.
    Journal: Gegenbaurs Morphol Jahrb; 1982; 128(1):68-77. PubMed ID: 7095385.
    Abstract:
    I. The findings of seminiferous tubules after total curettage of the testicular parenchyme confirm the previous studies of the author on the origin of regenerates whose source are the cells of the walls of the seminiferous tubules, that are parts of the Moskoff's islets in the tunica albuginea. 2. In the 7th month after operation, in the first place the interstitial components of the parenchyme are substituted. The submicroscopical finding shows hyperplasia of interstitial cells from undifferentiated stages, through modified fibroblasts up to the adult Leydig cell. 3. The findings in the 10th month after operation confirm the regeneration of the seminiferous tubules in which Sertoli cells and spermatogonias are present. No higher stages of germinal cells were observed. A pecularity of the submicroscopical picture at that time is the reduplication of the lamellar layer of the tubular wall with a great number of foldings. In the interstitium Leyding cells were observed.
