Four kinds of substitutive materials for hard tissues were inserted into tibias of rat, effect of substitutive materials on IGF-I mRNA expression level of cell in the interfaces of bone and four kinds of substitutive materials were studied by the technique in situ hybridization. It showed that the biomaterials could affect the level of IGF-I mRNA expression, the enhanced expression level was associated with cell proliferation, formation of matrix and calcification, formation of new bone. Measurement of IGF-I mRNA could attribute to judge the functional state of cell, and to predict the final character of the interface.
