CD44 is a family of glycoproteins involved in cell-cell and cell-matrix interactions. In addition to the major 90-kD form present on most hematopoietic cells, larger 140-230 kD forms are found on keratinocytes and carcinoma cell lines. These bigger isoforms of CD44 arise by alternative splicing that results in insertion of one or more of the "variant" exons(More)
Soluble isoforms of various adhesion molecules have recently been found in the circulation, but the physiologic effects of such molecules are still unconfirmed. Our earlier study suggests that the serum level of the 70- to 80-kDa form of CD44 (sCD44) parallels the clinical treatment response in patients with lymphoma. In the present study we investigated(More)
