Y Chromatin as Indicator of Chimaerism Following Bone Marrow Transplantation in Severe Combined Immunodeficiency

Determination of the Y chromatin body should rank among the battery of techniques used to assess the presence of grafted bone marrow cells in cases of male donor and female recipient. The method permits early determination of a take, and probably some measurement of its magnitude. This might provide correlation between level of grafted cells and occurrence of various parameters indicating an immune reconstitution and/or an eventual GVH reaction. The technique may be a highly sensitive marker for chimaerism in cases of histocompatibility between donor and recipient of different sexes.
