Integrin expression on phenotypically primitive adult mouse BM, FL, and MPB cells.

Cells were stained with MoAbs specific for Sca-1, c-kit, and each of the indicated adhesion molecules. Panel A shows the distribution of viable cells in each tissue according to Sca-1 and c-kit expression. Panel B shows differences in integrin expression on Sca-1⁺c-kit⁺ cells from FL (blue histograms), BM (red histograms), and MPB (green histograms) cells. Dashed lines represent background staining with appropriate isotype control antibodies. Data are representative of results obtained in 3 independent experiments.
