Relative increase in viable cell count of p210- and p230-expressing primary mouse bone marrow cultures expanded in the absence of either cytokines or autologous stroma.

Two days after gene transfer, p210 or p230 primary mouse bone marrow MNCs were selected for GFP expression by FACS. Data points represent the increase in total viable cell number relative to the number of GFP-positive cells recovered after FACS. Bars represent the mean of 6 independently derived p210 Bcr-Abl–expressing bone marrow cultures and 5 independently derived p230 Bcr-Abl–expressing bone marrow cultures.
