Study on the Histogenesis of uterine Leiomyomas from Their Relationship with Blood vessels

The blood vessels and the immature cellular clusters surrounded them in uterine leiomyomas or fetal uterine muscle layers have been obversed with H-E Staining, Gomori's reticulin staining and immunohistochemistry in which marked endothelial cells of blood vessels. It has been concluded that the endothelial cell can not differentiated into the cells of leiomyomas, the new-growth muscle cells of blood vessel walls in leiomyomas have the same origin with leiomyoma cells, and uterine leiomyoma cells are originated from the undifferentiated messenchamal cells.
