recently , however , lesley et al . have defined a thymocyte subpopulation which can be isolated by treatment of the thymus with cytotoxic anti-thy-1 antibodies and that seems to be enriched for thymocyte progenitors as measured first by its ability to repopulate transiently the thymus of an irradiated host , and second , by its high content of cells bearing pgp-1 ( refs 10 , 11 ) , a cell-surface glycoprotein of relative molecular mass 95,000 that is present on most or all prothymocytes of the bone marrow and on fetal thymocytes , but on only a few per cent of cells in the adult thymus .
