title: Congenitally osteosclerotic (oc/oc) mice are resistant to cure by transplantation of bone marrow or spleen cells from normal littermates.
abstract: The osteosclerotic mouse is a new, lethal recessive skeletal mutation which inherits osteopetrosis as an autosomal recessive. Affected mice are hypocalcemic and also have rickets. Osteoclasts are small and numerous with little evidence of function. This report examines the effects of bone marrow and spleen cell transplantation from normal littermates on survival and the radiographic appearance of the skeleton in 29 mutants. This procedure did not significantly prolong life or effect radiographic changes in the skeleton of most (27) recipients. However, two treated mutants lived for almost a year with radiographically normal skeletons. These variable responses to stem cell transplantation in an osteopetrotic mutant with rickets deserve further study.
