vGPCR-expressing HUVEC mimic spindle cells. HUVEC were infected with BABE or BABE-vGPCR retroviruses and grown for 72 hours. GFP-positive vGPCR expressing HUVEC exhibit a spindle cell-like morphology that resemble the spindle cells found in KS lesions. GFP expression ca. 60%. Images taken at 400× magnification.
