Transplantation of adult BM cells from EGFP transgenic animals can generate a population of Lin−/Sca-1+/c-kit− BM cells, albeit at low levels, in the BM of osteogenesis imperfecta (OI) recipients when transplanted intra-utero (Panaroni et al., 2009). This evidence concerns the gene KIT and osteogenesis imperfecta.
