Reticulin fibres are fine fibres that contain primarily collagen type III and are found in soft
blood-forming or blood-processing tissues, and are supportive elements in kidney, liver and
thymus. This study demonstrates for the first time the presence of reticulin fibres in the tunica
albuginea and peritubular tissue of seminiferous tubules of adult rat testes after staining with
the metallic silver impregnation method. Reticulin fibres of peritubular tissues may provide a
supportive framework for germinal epithelium of seminiferous tubules to allow the periphery …
