from this evidence , we hypothesized that the origin of suppressor macrophages in the peritoneal cavity induced by live bcg injection was mtx-sensitive ns cells in bone marrow , and that these ns cells were stimulated by a small dose of live bcg trapped in bone marrow after i.v . injection of a high dose of live bcg and migrated from bone marrow to the peritoneal cavity .
