Osteopetrosis was induced in lethally irradiated normal rats by cell infusion prepared from spleens of the osteopetrotic (op) mutant littermates. However, similar attempts to induce osteopetrosis in another strain of osteopetrotic rats, namely the "toothless" (tl) rats, were unsuccessful. This discrepancy between op and tl rats with regard to the transmission of the disease to normal littermates, parallels the response of the respective mutants to treatment by normal bone marrow cells: the op rat is cured, not the tl rat. The present findings confirm the cellular origin of osteopetrosis in the op rat, whereas the origin of the defect in the tl mutant remains obscure.
