Furthermore, data query showed that LuCaP 49 was CD57+ (B3GAT1; a marker associated with cells showing neuroendocrine differentiation), CD44-, CD107b+ (LAMP2, expressed by many prostate cancer cell types [31]), CD10-, CD133+; LuCaP 35 was CD57-, CD44-, CD107b+, CD10+, CD133-. This evidence concerns the gene CD44 and Familial prostate cancer.
