to search the abnormality in prethymic t-cell precursors in lpr/lpr ( lpr ) mice , rearrangement and expression of t-cell receptor ( tcr ) genes were investigated in long-term cultured bone marrow ( ltbm ) cells of lpr mice , in which the developmental steps of t-cell precursors may be better synchronized than those in bone marrow ( bm ) cells .
