Collagen fibrillogenesis in the presence of lanthanides.
Following removal of most of the telopeptide regions with pepsin, bovine dermal collagen gelled more slowly to form fibrils with a weak banding pattern. The reduction in gelling rate reflected an increase in the length of the nucleation phase and a lower rate of turbidity increase during the growth phase; the activation energy of both phases was increased. Lanthanide ions, phosphate, or, to a l...
متن کاملFibrillogenesis in continuously spun synthetic collagen fiber.
The universal structural role of collagen fiber networks has motivated the development of collagen gels, films, coatings, injectables, and other formulations. However, reported synthetic collagen fiber fabrication schemes have either culminated in short, discontinuous fiber segments at unsuitably low production rates, or have incompletely replicated the internal fibrillar structure that dictate...
متن کاملRegulators of Collagen Fibrillogenesis during Molar Development in the Mouse
Development of mammalian teeth and surrounding tissues includes time-space changes in the extracellular matrix composition and organization. This requires complex control mechanisms to regulate its synthesis and remodeling. Fibril-associated collagens with interrupted triple helices (FACITs) and a group of small leucine-rich proteoglycans (SLRPs) are involved in the regulation of collagen fibri...
متن کاملFibronectins, their fibrillogenesis, and in vivo functions.
Fibronectin (FN) is a multidomain protein with the ability to bind simultaneously to cell surface receptors, collagen, proteoglycans, and other FN molecules. Many of these domains and interactions are also involved in the assembly of FN dimers into a multimeric fibrillar matrix. When, where, and how FN binds to its various partners must be controlled and coordinated during fibrillogenesis. Step...
متن کاملCOMP acts as a catalyst in collagen fibrillogenesis.
We have previously reported that COMP (cartilage oligomeric matrix protein) is prominent in cartilage but is also present in tendon and binds to collagens I and II with high affinity. Here we show that COMP influences the fibril formation of these collagens. Fibril formation in the presence of pentameric COMP was much faster, and the amount of collagen in fibrillar form was markedly increased. ...
