Growth of pro-B cells in stromal cell-free cultures

Bone marrow and fetal liver pro-B cells have been grown long-term in stromal cell-free cultures supplemented with IL-7, Flt3L, and SCF. When the cultured cells are transplanted into immune-deficient mice they give rise to mature B cells that participate in T-cell dependent immune responses.
