Chemotactic effect of enamel matrix

摘要

Summary.Enamel matrix was isolated from forming canine teeth in monkeys and applied to experimental cavities in incisor teeth. In another experiment, enamel matrix from rat incisors was injected intraperitoneally; the peritoneal exudate was collected and grownin vitro.The dentine surface was covered by mast cells while a significant number of mast cells were present in the peritoneal exudate. Enamel matrix appears to be chemotactic for mast cells which may be involved in the initiation of cementogenesis
