title: Expression of platelet-derived endothelial cell growth factor in prostatic adenocarcinoma.
abstract: Angiogenesis is thought to play critical roles in local tumor growth and eventual metastasis. No studies have examined the expression of platelet-derived endothelial cell growth factor (PD-ECGF) in prostatic tissues. Prostatic tissues were obtained from 36 prostatic adenocarcinoma patients. We assessed the expression of PD-ECGF using ELISA and immunohistochemistry. The mean level of PD-ECGF in prostatic adenocarcinomas was higher than that in neighboring normal prostatic tissues in ELISA. Immunohistochemistry showed that the expressions of PD-ECGF, which were associated with increase of microvessel count, were found in the endothelial cells, macrophages, lymphocytes, or fibroblasts. These results suggest that PD-ECGF is involved in the development of prostatic adenocarcinoma.
