True or False? An immature B cell that readily binds to a bone marrow stromal cell will likely exit the bone marrow and migrate to a secondary lymphoid organ for further maturation.

TRUE

Stromal cells provide a microenvironment conducive to the growth of immature B cells. Immature B cells which readily bind to them will most likely continue to mature and exit the bone marrow into a secondary lymphoid organ where they will complete development.
