| Outline of Final Research Achievements |
We have established human immortalized bladder smooth muscle cell (hBS11). The hBS11 showed the extremely unique property that could bi-directionally go back and forth in the undifferentiated proliferative state and differentiation state under culture. It is thought that from a result of the histopathological analysis in a reproduction process the in vivo smooth muscle cell changes the property of the cell, that is "differentiation state ⇒ undifferentiated proliferative state ⇒ differentiation state". The present study demonstrates that the hBS11 cell maintains plasticity of the differentiation that a smooth muscle cell originally has.
Immortalized hBS11 cell provides useful analytical system for elucidation of the pathophysiological mechanism of lower urinary tract dysfunction and the development of the new treatment options, in addition to the elucidation of molecular differentiation mechanism, reproduction mechanism, and the function control mechanism of the smooth muscle cell.
