| pubmed-article:6451029 | pubmed:abstractText | Functional capacities of T-cells precursors have been evaluated by cell culture experiments after fractionation of bone marrow cells from normal and nude mice by 1 g velocity sedimentation. The results indicate that the T-cell precursors in the bone marrow are cycling cells, that T-cell precursors in the bone marrow of nude mice have more limited potentials than those of normal mice, and that both Thy-1.2-positive and Thy-1.2-negative precursors are stimulated by T-cell activators. | lld:pubmed |
