PDGF-Related Proteins in Human Brain Tumors
The platelet-derived growth factor (PDGF) is one of the well known mitogenic factors for glial cells and connective tissue cells [1–3]. It is suggested that PDGF-related protein has an autocrinic effect and participates in malignant neoplastic transformation [4–6]. The mRNA expression of A and B chains was detected in some glioma cells . It was reported that meningiomas expressed both PDGF and its receptor . Expression of the PDGF-related proteins in the various types of brain tumors has not yet been estimated. We have detected 17 kilodalton (kd) PDGF-related proteins in glioma cells , and obtained rabbit antibody against glioma-derived PDGF-related protein, with which we studied the presence of PDGF-related proteins in various cultured human cells and brain tumors.
