Abstract
Mouse RBC (M) rosettes were investigated on lymphocytes from peripheral blood (PB) and various tissues in 20 patients with chronic lymphocytic leukemia and 1 with follicular lymphoma. In all cases studied, the percentage of M rosettes was significantly higher in PB (median 64%) than in bone marrow (median 15%) and lymph node (median 12%). These differences were statistically significant (P < 0.01). The possibility that these differences were related to technical factors was ruled out by a number of control procedures. The different expression of M rosette formation apparently reflects the property which determines whether a lymphocyte enters the peripheral blood or remains fixed in the tissues.
