    CTLA4-Ig, Vascularized Bone Marrow and Donor Bone Marrow Cells Successfully Negate the Development of Acute Skin Rejection of Vascularized Composite Allografts in MHC Class I Mismatched Recipients.

    I. Schol, Z. Ng, A. Lellouch, A.-R. Gama, J. Kurtz, C. Cetrulo.

    Massachusetts General Hospital, Boston

    PURPOSE: Previously we have shown that MHC class I-mismatched recipient miniature swine (n=3) experienced rejection (from POD42 onwards) of the epidermal component of fasciocutaneous vascularized…
