Abstract: A new class of molecules, C1—OH tributanoylated hexosamines, including, for example, GalNAc, GlcNAc and ManNAc, are demonstrated to increase cartilage-like tissue accumulation by IL-1?-stimulated chondrocytes. Furthermore, all three molecules reduced NFKB1 and I?B? driven gene expression, consistent with NF?B inhibitory properties of these analogs. GalNAc-a exposure produced the greatest ECM accumulation by IL-1?-stimulated chondrocytes. However, GalNAc-a exposure produced an opposite effect on MSC exposure, where a decrease in ECM accumulation was observed. These findings are in support of the function of NF?B signaling during limb development and growth plate chondrogenesis. The present invention shows the capability of this new class of hexosamine analogs as disease-modifying agents for treating cartilage damage.

Abstract: The present invention provides biomaterial compositions that can immobilize HA to the ocular surfaces through an HABpep and transmembrane mucins and collagen of ocular tissues can act as anchoring sites. These biomaterial compositions provide prolonged HA binding and retention in both ex vivo and in vivo animal models. HA eye drop solutions with these the inventive biomaterials can prolong the biological and physical benefits to the ocular surface and potentially be more effective in treating eye disorders including dry eye than standard HA-eye drop presently available. Methods of making and use of the compositions are also provided.

Abstract: The present invention provides novel biomaterial compositions and methods having a technology to improve retention of hyaluronic acid (HA). The biomaterial compositions utilize small HA binding peptides that is tethered to synthetic biocompatible polymers. When tethered to the polymers, the peptide region allows the polymers to bind to HA. The biocompatible polymers are modified to contain a crosslinking group so that the HA can be incorporated into a scaffold and retained in place. The novel biomaterial 1 compositions can be made into hydrogel compositions and used in a variety of tissue applications, using mild crosslinking conditions and they also have the ability to be degraded with hyaluronidase if needed. Furthermore, the novel biomaterial compositions will enable enhanced interaction between the scaffold and encapsulated cells for a wide variety of tissue engineering applications. Methods of making hydrogel compositions and their use are also provided.

Abstract: The present inventors employed cyclodextrins for use as a proteoglycan substitute to engineer a biomimetic collagen-based matrix composition. The resulting incorporation of cyclodextrin in the inventive collagen compositions increased collagen thermal stability and reduced collagen fibrogenesis. As a result, a thick, transparent and mechanically strong collagen-based composition was formed. This cyclodextrin-collagen composition holds a great potential to be used as a therapeutic eye patch for corneal repair. Additionally, the composition can support development of multi-layered structures, with different layers promoting different biological properties. Methods for making these inventive compositions and their use are also provided.
