Identification of CD44^high cells in the PLCCLs by flow cytometry analysis.

<p>A small sub-population of CD44^high cells could be identified in the SCLC cell line LC004 (6.63%) (<b>A</b>); the LCC cell line LC006 (2.79%) (<b>B</b>); the AC cell line LC007 (6.69%) (<b>C</b>) and the SCC cell line LC021 (14.95%) (<b>D</b>), respectively. Left panel: isotype control Ab; right panel: CD44 Ab. Data shown are from representative experiments (n>3).
