Background: Diabetic disorders can lead to muscle atrophy. The aim of this study was to investigate the combination of resistance training and endothelial progenitor cell injection on the expression of horseshoe muscle atrophy factor in diabetic rats. Methods: 30 rats (6 weeks old weighing 200 20 200 g) were randomly divided into five groups: healthy baseline, control diabetic, trained diabeti...
Poor angiogenesis is a major road block for tissue repair. The regeneration of virtually all tissues is limited by angiogenesis, given the diffusion of nutrients, oxygen, and waste products is limited to a few hundred micrometers. We postulated that co-transplantation of hematopoietic and mesenchymal stem/progenitor cells improves angiogenesis of tissue repair and hence the outcome of regenerat...
introduction insulin-like growth factor i (igf-i) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. igf-i plays the roles via the receptor (igf-ir) signaling pathway. igf-ir unlike igf-i is expressed strongly in the developing liver, but much more weakly in adults. objective: we hypothesiz...
The umbilical cord is a rich source for progenitor cells with high proliferative potential including mesenchymal stromal cells (also termed mesenchymal stem cells, MSCs) and endothelial colony forming progenitor cells (ECFCs). Both cell types are key players in maintaining the integrity of tissue and are probably also involved in regenerative processes and tumor formation. To study their biolog...
Abstract Testicular development and function rely on interactions between somatic cells the germline, but similar to other organs, regenerative capacity declines in aging disease. Whether adult testis maintains a reserve progenitor population remains uncertain. Here, we characterize recently identified mouse interstitial expressing transcription factor Tcf21. We found that TCF21 lin are bipoten...
Repair of parenchyma by stem/progenitor cells is seen as a possible alternative to cure acute and chronic renal failure in future. To learn about this therapeutic purpose, the formation of nephrons during organ growth is under focus of present research. This process is triggered by numerous morphogenetic interactions between epithelial and mesenchymal cells within the renal stem/progenitor cell...
Adult stem cells and progenitor cells can integrate and respond to appropriate extracellular stimuli in the form of hormones and growth factors, or contact with the extracellular matrix (ECM) and neighboring cells. The delicate balance between the dormancy of progenitor cells and their timely proliferation and differentiation is a crucial parameter in tissue homeostasis that is often perturbed ...
