Extra skeletal Ewings sarcoma is a rare entity. The primary bladder localization exceptional, their diagnosis difficult because it extremely in this place and of diagnostic difficulties posed by group very heterogeneous tumors. Its clinical presentation similar to that transitional cell carcinoma, however the two entities must be distinguished protocols for treatment are different. dependent on...

Skeletal and smooth muscle can mutually transdifferentiate, but little molecular insight exists as to how each muscle program may be subverted to the other. The myogenic basic helix-loop-helix transcription factors MyoD and myogenin (Myog) direct the development of skeletal muscle and are thought to be dominant over the program of smooth muscle cell (SMC) differentiation. Myocardin (Myocd) is a...

The ubiquitously expressed large GTPase Dynamin 2 (DNM2) plays a critical role in the regulation of intracellular membrane trafficking through its crucial function in membrane fission, particularly in endocytosis. Autosomal-dominant mutations in DNM2 cause tissue-specific human disorders. Different sets of DNM2 mutations are linked to dominant intermediate Charcot-Marie-Tooth neuropathy type B,...

Diabetes mellitus is defined as a group of metabolic diseases that are associated with the presence of a hyperglycemic state due to impairments in insulin release and/or function. While the development of each form of diabetes (Type 1 or Type 2) drastically differs, resultant pathologies often overlap. In each diabetic condition, a failure to maintain healthy muscle is often observed, and is te...

Progress has recently been made toward the production of human skeletal muscle cells from induced pluripotent stem (iPS) cells. However, the functional and ultrastructural characterization, which is crucial for disease modeling and drug discovery, remains to be documented. We show, for the first time to our knowledge, that the electrophysiological properties of human iPS-derived skeletal myocyt...

Bone metastases in patients with renal cell carcinoma are associated with a high risk of skeletal complications. Therefore, a subset analysis of a larger clinical trial was performed to determine the efficacy of zoledronic acid in renal cell carcinoma patients. Patients with bone metastases from solid tumors other than breast or prostate cancer (n=773) were randomized to receive zoledronic acid...

Objectives- To isolate, culture-expand and differentiate mesenchymal stem cells from ovine bone marrow and determine their culture requirements for high expansion rate. Design- Experimental study. Animals- Five Shal sheep. Procedures- In this study, ovine marrow cells were plated and culture expanded through 3 successive subcultures. The resultant cells were then plated at differentiating condi...

OBJECTIVES The aim of this study was to evaluate the therapeutic potential of human skeletal muscle-derived myoendothelial cells for myocardial infarct repair. BACKGROUND We have recently identified and purified a novel population of myoendothelial cells from human skeletal muscle. These cells coexpress myogenic and endothelial cell markers and produce robust muscle regeneration when injected...
