FGF7 and myxoid liposarcoma: For example, while VEGF (not shown) was expressed in all of the STS subtypes, TGFB1 and FGF7 (keratinocyte growth factor) were expressed in ~78% of LMS but only ~40% of non-myxoid liposarcoma, while OGFR was expressed in ~43% of myxoid liposarcoma, 100% of non-myxoid liposarcomas, ~67% of leiomyosarcomas, and none of the AF samples.
