[Reaggregating brain cell cultures: methodical aspects, morphological and biochemical characteristics, possible applications].

A survey is given of the characteristics of the culture system of rotation-mediated reaggregating brain cell cultures. Aggregates of dissociated fetal brain cells of different species undergo morphological and biochemical differentiation in vitro, which resembles normal brain development in vivo. The usefulness of this system, e.g. for virological investigations in veterinary medical research is discussed.
