These three SCLC cell lines showed expression of CD24 to a variable degree In addition to CD133-positive DMS53 and BHGc10, significant expression of this antigen in GLC14 and GLC16 SCLC lines and peak labeling of BHGc16 CTC and NCI-H69 cells was found (Fig. 5). The gene discussed is CD24; the disease is small cell lung carcinoma.
