Abstract

Evidence is presented that a mitogen can be produced from myelin basic protein (MBP) which may be related to the Schwann cell proliferation characteristic of Wallerian degeneration. Myelin derived from the shiverer mutant which is devoid of MBP is also devoid of mitogenic activity. Absorption of the mitogen with a polyclonal antisera to MBP abolishes the mitogenic effect. In addition, only liposomes containing MBP are mitogenic to cultured Schwann cells; liposomes containing other myelin-specific proteins do not stimulate Schwann cell division. These results directly demonstrate the MBP origin of a mitogen for Schwann cells.
