Finally, flow cytometry assays showed high expression levels of CD44, CD73, CD90, CD105, CD133, and CD146 in OM-MSCs, while OM-MSCs did not express CD34 and CD45, with the purity rate of OM-MSCs exceeding 97% (Additional file 1: Fig. S1h). The gene discussed is PROM1; the disease is ocular melanoma.
