three cell lines ( vmdk ) , derived from a spontaneous murine astrocytoma , which exhibit both morphological and antigenic characteristics of astrocytes in vitro ( pilkington et al . 1983 ) , have been injected intracerebrally and subcutaneously into syngeneic mice at a range of concentrations in order to assess the number of cells required to produce the highest yield of tumours with the shortest possible latent period .
