Abstract:
Objective To investigate the effect of fibroblast growth factor receptor 3(FGFR3) in development phase of murine small intestine.Methods Wild type mice and their littermate FGFR3+ mice were used to observe their morphology and proliferation characteristics of epithelia of small intestinine in development phase and changes of FGFR3 expression.Results Mutant mice had lower density and their villa were lower than those of the controls.But to the depth of crypt,the results were conversely.Cells in proliferation mainly located in intestine crypt.Mutant mice had more proliferation than the controls at every time point.Expression of FGFR3 was detected at birth(day 1),and the expression was maximal from day7 to day 21,decreasing rapidly thereafter to reach the relatively low at day35.And the expression of FGFR3 also located in intestine crypt,overlapping with that of Brdu.Conclusion FGFR3 improves formation of murine intestine crypt in development phase.
