CELLULAR REQUIREMENTS FOR THE REJECTION OF SKIN ALLOGRAFTS IN RATS
The role of bone marrow-derived cells in the rejection of skin allografts in rats was investigated. Lewis rats, rendered tolerant of BN antigens and bearing healthy grafts, were thymectomized, irradiated with 900 rad, and injected with varying doses of either normal isologous bone marrow, normal ly...

Article The role of bone marrow-derived cells in the rejection of skin allografts in rats was investigated. Lewis rats, rendered tolerant of BN antigens and bearing healthy grafts, were thymectomized, irradiated with 900 rad, and injected with varying doses of either normal isologous bone marrow, normal lymph node cells, and/or lymph node cells presensitized to BN antigens. In some experiments rats were also adoptively sensitized to tuberculin. Results showed that, although necessary for the elicitation of tuberculin skin reactions, bone marrow cells are not needed for the rejection of previously tolerated skin allografts. Rats receiving lymph node cells alone rejected their grafts in about 6–7 days. In addition, rats injected with bone marrow alone also rejected their grafts, although significantly later than did lymph node cell recipients, indicating that rat marrow contains a population of cells capable of reacting to transplantation antigens. These cells were found capable of reacting to major transplantation antigens but not minor as they were ineffective in causing the rejection of Ag-B compatible Fischer skin grafts. From experiments utilizing bone marrow from neonatally thymectomized donors and cells treated with an antiserum to rat T cells, these competent cells in the marrow were shown to be thymus derived.

The role of bone marrow-derived cells in the rejection of skin allografts in rats was investigated.
