title: Growth factors for fetal and adult human astrocytes in culture.
abstract: Using a recently developed method for the determination of cell proliferation in culture, we assessed the effects of several growth factors on their capability to promote proliferation of astrocytes derived from human fetuses or adults. Factors tested included fibroblast growth factor, epidermal growth factor, platelet-derived growth factor, glial growth factor from bovine pituitary, nerve growth factor, interleukin-2, dibutyryl cyclic adenosine monophosphate, and 4 beta-phorbol 12,13-dibutyrate. The results show that astrocytes from human adults do not undergo proliferation in vitro even in the presence of these agents and that in the case of fetal astrocytes, only glial growth factor from bovine pituitary, platelet-derived growth factor and the phorbol ester were mitogenic. In addition, the capability of fetal astrocytes to proliferate appears to decrease with the increasing length of time they have been maintained in culture.
