Adipose Tissue-Derived Stem Cells Ameliorate Diabetic Bladder Dysfunction in a Type II Diabetic Rat Model.
Summary of "Adipose Tissue-Derived Stem Cells Ameliorate Diabetic Bladder Dysfunction in a Type II Diabetic Rat Model."
Diabetes mellitus is associated with a broad constellation of voiding complaints that are often multifactorial and resistant to currently available therapies. The leading causes of diabetic bladder dysfunction (DBD) include alterations in the bladder smooth muscle, neuronal degeneration, and urothelial dysfunction. Adipose tissue-derived stem cells (ADSCs), a type of mesenchymal stromal cells, have shown promise as a novel tissue regenerative technique that may have utility in DBD. The aim of this study is to determine the efficacy and mechanism by which ADSCs may ameliorate DBD in rats fed a high-fat diet and treated with low-dose streptozotocin to induce type II diabetes. Improved voiding function was noted in ADSCs-treated rats as compared with phosphate-buffered saline-treated rats. Though some ADSCs differentiated into smooth muscle cells, paracrine pathway seems to play a main role in this process, thus resulting in reduction of apoptosis and preservation of "suburothelial capillaries network."

Medical and Biotech [MESH] Definitions
Adipose Tissue
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
Mesenchymal Stem Cells
Cells that can develop into distinct mesenchymal tissue such as BONE; TENDONS; MUSCLES; ADIPOSE TISSUE; CARTILAGE; NERVE TISSUE; and BLOOD and BLOOD VESSELS.
Neoplasms, Adipose Tissue
Neoplasms composed of fatty tissue or connective tissue made up of fat cells in a meshwork of areolar tissue. The concept does not refer to neoplasms located in adipose tissue.
Myeloid Progenitor Cells
Stem cells derived from HEMATOPOIETIC STEM CELLS. Derived from these myeloid progenitor cells are the MEGAKARYOCYTES; ERYTHROID CELLS; MYELOID CELLS; and some DENDRITIC CELLS.
Leukopoiesis
The process of generating white blood cells (LEUKOCYTES) from the pluripotent HEMATOPOIETIC STEM CELLS of the BONE MARROW. There are two significant pathways to generate various types of leukocytes: MYELOPOIESIS, in which leukocytes in the blood are derived from MYELOID STEM CELLS, and LYMPHOPOIESIS, in which leukocytes of the lymphatic system (LYMPHOCYTES) are generated from lymphoid stem cells.
