title: [Studies on neurinomas and neurofibromas in tissue culture (author's transl)].
abstract: 10 acoustic neurinomas, 2 spinal cord neurinomas and 3 neurofibromas of von Recklinghausen's disease were elaborately studied by monolayer tissue culture method and Gelfoam organ culture method. Four morphological types were found in the acoustic and spinal cord neurinoma. (1) multinucleated cells (type I), dividing into bipolar spindle-shaped cells. (2) bipolar spindle-shaped cells (type II), forming of palisade fashion in the monolayer tissue culture method. (3) fibroblastic cells (type III), tending to predominate in the long-term cultures. (4) round cells (type IV), gathering to the Gelfoam mesh in the organ culture method. Neurofibroma of von Recklinghausen's disease was divided into cells of two types in the tissue culture. (1) spindle-shaped cells, rarely observed, and have been thinking that the cells originated from schwann cells. (2) round cells, having the macrophagic character, are predominant in the long-term culture.
