The astrocytic nature of glioblastoma demonstrated by tissue culture

Forty-eight cerebral astrocytomas and glioblastomas were studied by tissue culture for two purposes: (a) the establishment of a definite growth pattern of cerebral astrocytomas and (b) the comparison of this growth pattern and that of glioblastomas. According to the grade of malignancy the series was divided into four groups: low-, middle-, and high-grade astrocytomas and undifferentiated glioblastomas.
