title: Differentiation markers and accessory function of murine macrophages derived from cultured bone-marrow stem cells.
abstract: Murine bone-marrow cells cultured in the presence of colony-stimulating factor from mouse-lung-conditioned medium give rise to macrophages which function as accessory cells in antigen-specific T helper cell induction. Virtually all Ia+ bone-marrow stem cell-derived macrophages express determinants encoded in the I-A subregion. A second set of macrophages bears I-A as well as I-E/C-endoced determinants. The products of the I-A and I-E/C subregion, but not those of the I-J subregion, are involved in T helper cell induction.
