Note

The specific concept (C22490, NCIt, "Tumor Cell Graft") (UMLS:C1519674) is not used, since grafts may not be cell suspensions, but rather entire tumors, fragments of tumor tissue, etc. Whether the graft is a xenograft or homograft is not specified, and may be encoded elsewhere (e.g., by encoding the species of origin). The non-tumor specific concept (246345001, SCT, "Graft material") may be used when the graft is not a tumor (though strictly speaking, it is a SNOMED attribute rather than substance; UMLS:C0181074 does not make such a distinction).
