Using a reverse flow cytometric gating strategy with Lin- selection stain (which includes anti-CD3, -CD19, -CD20, -CD14, -CD16, -CD56 mAbs) Lin-CD34+DNAM-1bright precursor cells could be detected in all the patients with non-Hodgkin Lymphoma, NSCLC and Kaposi Sarcoma (Figure 1A). The gene discussed is NCAM1; the disease is non-small cell lung carcinoma.
