WebIntroduction. Glia maturation factor (GMF), as a growth and differentiation factor, was first isolated from bovine brain in 1972. 1 The protein is actually a mixture of two compounds: glia maturation factor-β (GMFB) and GMF-γ. GMFB was further purified from crude GMF. 2 GMFB is expressed predominantly in the central nervous system (CNS), 3 while its …
