CD11b⁺CD14⁻MHCII⁻ cells suppress T cell proliferation.

<p>Facs sorted CD11b⁺CD14⁻MHCII⁻ cells isolated from a dog with osteosarcoma or healthy PBMCs were co-incubated with mitogen-stimulated CD4⁺ and CD8⁺ T cells isolated from a healthy dog for 72 hs. No stimulated cells were used as negative control. Proliferative responses were measured by ³H-thymidine incorporation from experiments performed in triplicate. CPM, counts per minute. Mean ± SEM are shown.
