Abstract
A precementum- and/or cementum-derived chemotactic factor (CCTF) of a tooth of a Mammalian is characterized by a molecular weight measured by SDS-PAGE of 67000.+-.1000. A process for purifying a precementum- and/or cementum-derived gingival fibroblast chemotactic factor (CCTF) of a Mammalian tooth includes eluting a protein mixture from precementum and/or cementum of a Mammalian tooth and purifying the precementum- and/or cementum-derived chemotactic factor (CCTF) from the eluted protein mixture by molecular weight fractionation, ion-exchange adsorption chromatography and hydroxyapatite adsorption chromatography. In the process for purifying the gingival fibroblast chemotactic factor (CCTF) the Mammalian is preferably a bovine.
