Abstract:
Objective To study apoptosis and morphological characteristics in the developing renal corpuscles of mouse kidney. Methods Light,transmission electron microscope and TUNEL technique were used to observe apoptosis in the developing renal corpuscles of different embryonic and postnatal mice. Results Apoptotic cells could be found when renal corpuscles occurred at embryonic day 14(E14).It peaked around E18 and decreased thereafter.Electron microscope revealed that apoptotic cells had morphological characteristics such as margination of condensed nuclear chromatin,shrinking cytoplasm.Apoptosis of endothelial cells and podocytes were more frequent.Two results of apoptotic cells were observed,1. being ingested by neighboring cells; 2. apoptotic cells were dropping into glomerular capillary lumens or Bowman capsules.Conclusion Apoptotic cells were found in all the time during the development of mouse renal corpuscles.It might play an important role in the development of renal corpuscles.
