ABSTRACT
Objective To examine the expression of Noggin in CNS of the developing rat. Methods In situ hybridization histochemistry(ISHH) was performed using digoxigenin-labeled cRNA as probes. Results It was revealed that densely and deeply stained noggin positive cells were detected in cortex,hippocampus,cerebellum,and nucleus of hypothalamus and thalamus in embryonic day(E)16 rats.The number of noggin positive cells was increased in the thalamus and medulla oblongata at postnatal day(P)1-2,whereas decreased in the hippocampus and cortex.The number of noggin positive cells was decreased significantly in brain at 1 week postnatal(P1W),and began to increase at P2W,especially in the cortex and hippocamps.Strong positive signal can be detected in the frontal cortex,parietal cortex,cingulated cortex,hippocampus,olfactory and cerebellum at 1 month postnatal(P1M).The expression of noggin begins to decline at P3M,only sparse noggin positive cells can be seen in CNS at P18M.Furthermore,there is no noggin positive cells seen in the spinal cord of rats during development.Conclusion Our results indicated that noggin could play an important role in CNS development of rats.
