Ability of antibodies to the IL-7R and/or c-Met to inhibit the stimulation of mouse bone marrow cells by rIL-7 or scIL-7/HGFβ. Culture-generated BM cells (4 × 105 cells/well) from IL-7-/- mice were incubated for 3 days in the presence of rIL-7 (10 μg/mL) or scIL-7/HGFβ (30 μg/mL) to which antibodies against IL-7Rα, γc, and/or c-Met (10 μg/mL) were added. Incorporation of [methyl-3H] thymidine (mean counts per minute [CPM] ± SD) was determined after a 12-hour pulse. *P < .05 between antibody-treated and untreated values (similar results were obtained with isotype controls). **P < .05 versus value for anti-IL-7Rα or anti-HGFR alone. One representative experiment of 4 is shown.
