Mouse One has a defect that prevents T lymphocytes from maturing. Mouse Two has a defect that prevents complete thymus development. Neither mouse has mature T cells. What is one way to induce the development of mature T cells in Mouse One?
Responda
Introduce bone-marrow stem cells from Mouse Two into Mouse One
Inject antibodies against defective T cells into Mouse One
Graft thymus from Mouse Two into Mouse One
Inject antibody against CD4 in Mouse One
