Notably, both samples showed stromal and tumour cell expressions of markers associated with self-renewal and differentiation of CNS cell types such as Musashi-1, SOX2, POU3F2, PDGFRA, GFAP and Vimentin, as well as angiogenic factors including FGF2, VEGF and Angiopoietin 2. The gene discussed is PDGFRA; the disease is neoplasm.
