Abstract:
Objective To observe the chronological and spatial expressions of transforming growth factor-? receptor Ⅱ(TGF-?RⅡ) and fibronectin(Fn) in uriniferous tubules of mouse kidney and investigate the correlation of TGF-?RⅡ and Fn with development of uriniferous tubules.Methods The expressions and content changes of TGF-?RⅡ and Fn were examined by immunohistochemistry and stereological method in mouse kidneys on embryonic days 12,14,16 and 18 and postnatal days 1,3,7,14,21,28 and 42.Results The expression of TGF-?RⅡ was found in all stages of renal tubules and collecting ducts and increased gradually with the kidney development;however,the expressions were obvious in all stages of proximal tubules and collecting ducts,while little was observed in all stages of distal tubules.The expression of Fn was detected in all stages of renal tubules and collecting ducts and also increased gradually with the kidney development.Conclusion TGF-?RⅡ and Fn might play an important role in the development and maturation of uriniferous tubules of mouse kidney.
