A synthetic glycosaminoglycan mimetic (RGTA) modifies natural glycosaminoglycan species during myogenesis.
Crucial events in myogenesis rely on the highly regulated spatiotemporal distribution of cell surface heparan sulfate proteoglycans to which are associated growth factors, thus creating a specific microenvironment around muscle cells. Most growth factors involved in control of myoblast growth and differentiation are stored in the extracellular matrix through interaction with specific sequences ...
متن کاملA synthetic glycosaminoglycan mimetic binds vascular endothelial growth factor and modulates angiogenesis.
In a previous study, we showed that in situ injection of glycosaminoglycan mimetics called RGTAs (ReGeneraTing Agents) enhanced neovascularization after skeletal muscular ischemia (Desgranges, P., Barbaud, C., Caruelle, J. P., Barritault, D., and Gautron, J. (1999) FASEB J. 13, 761-766). In the present study, we showed that the RGTA OTR4120 modulated angiogenesis in the chicken embryo chorioall...
متن کاملGlycosaminoglycan mimetic peptide nanofibers promote mineralization by osteogenic cells.
Bone tissue regeneration is accomplished by concerted regulation of protein-based extracellular matrix components, glycosaminoglycans (GAGs) and inductive growth factors. GAGs constitute a significant portion of the extracellular matrix and have a significant impact on regulating cellular behavior, either directly or through encapsulation and presentation of growth factors to the cells. In this...
متن کاملGlycosaminoglycan mimetics (RGTA) modulate adult skeletal muscle satellite cell proliferation in vitro.
Muscle regeneration occurs through the activation of satellite cells, which are stimulated to proliferate and to fuse into myofibers that will reconstitute the damaged muscle. We have previously reported that a family of new compounds called "regenerating agents" (RGTAs), which are polymers engineered to mimic heparan sulfates, stimulate in vivo tissue repair. One of these agents, RG1192, a dex...
متن کاملExpression of Glycosaminoglycan Epitopes During Zebrafish Skeletogenesis
BACKGROUND The zebrafish is an important developmental model. Surprisingly, there are few studies that describe the glycosaminoglycan composition of its extracellular matrix during skeletogenesis. Glycosaminoglycans on proteoglycans contribute to the material properties of musculo skeletal connective tissues, and are important in regulating signalling events during morphogenesis. Sulfation moti...
