Cell Biology of Ureter Development

Explorer Cell Biology of Ureter Development

The mammalian ureter contains two main cell types: a multilayered water-tight epithelium called the urothelium, surrounded by smooth muscle layers which, by generating proximal to distal peristaltic waves, pump urine from the renal pelvis toward the urinary bladder. Here, we review the cellular mechanisms involved in the development of these tissues, and the molecules which control these proces...

Cell Biology Modeling Development

The fundamental problem of pattern formation for example, how to specify body axes, limbs, digits during development comes down to interpreting a common set of genetic instructions differently at different locations in space (Wolpert 1969). (See Figure 1.1 for an illustration). In all multicellular animals, this process is orchestrated by morphogens, molecules that are produced at discrete site...

A review of Biology and clinical use of Mesenchymal stem cell: an immune -modulator progenitor cell

Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

PRIMARY LEIOMYOSARCOMA OF THE URETER

Since 1943, fourteen cases of primary leiomyosarcoma of the ureter have been reported in English literature. The fifteenth case is presented here with a brief review of the significant aspects of the previous reports.
