Noticeably, a very recent study showed the higher concentration of lipoprotein lipase (LPL) and collagen type V alpha 2 chain (COL5A2) in exosomes derived from ovarian cancer cells (SKOV-3) compared to ovarian surface epithelial cells (HOSEPiC) by proteomic and lipidomic analysis [171]. Here, COL5A2 is linked to ovarian cancer.
