CD68

a type I transmembrane protein present on monocytes, macrophages, osteoclasts, mast cells, cytoplasmic granules, activated platelets, and large lymphocytes; expressed in neuroma Schwann cells, in nerves undergoing wallerian degeneration, in myeloid cell tumors, and in anaplastic lymphomas and epithelial tumors.
