摘要： A device for inhibiting adhesion of apposing human body tissue layers includes a scaffold having a designated mean pore size, relative density, and degradation half-life. The scaffold may be operably positioned between apposing tissue layers, such as proximate adhesiogenic layers at a wound site, so as to permit remesothelialization of the tissue without formation of fibrous adhesions. The scaffold device of the invention inhibits adhesion formation by promoting contractile cell migration away from the wound site for a predetermined period of time. The invention further relates to device and methods for promoting internal tissue regeneration, and for provision and/or dispensation of therapeutic and/or diagnostic agents in vivo.

摘要： The invention provides methods and compositions for making and using collagen-glycosaminoglycan three-dimensional scaffolds immobilized with biomolecules that are spatially and temporally patterned. The method comprises adding benzophenone to a collagen-glycosaminoglycan three dimensional scaffold in the dark; adding one or more biomolecules to one or more areas of the collagen-glycosaminoglycan three-dimensional scaffold (which can be done optionally in the dark or in the light); and exposing the collagen-2glycosaminoglycan three-dimensional scaffold to light at a wavelength of about 350 to about 365 nm.
