Cells derived from sporadic and AIDS-related Kaposi's sarcoma reveal identical cytochemical and molecular properties in vitro.

We have established 40 cell cultures from biopsies of 5 patients with sporadic Kaposi's sarcoma (KS) and compared them with cell cultures derived from KS biopsies of AIDS patients. Immunocytochemical staining of sporadic KS cells revealed the same endothelial cell markers as those expressed on AIDS-KS cells, indicating that both types of KS might be of… CONTINUE READING
