摘要： A fundamental deficiency with current biological cell encapsulation technology is that passive material barriers cannot protect biological cells from exposure to cytokines and other small, diffusible cytotoxic molecules produced by activated immune cells, subsequently leading to biological cell destruction. The present invention provides an immunoisolative encapsulation system that actively and locally suppresses immune response using Fas receptor binding agents.

摘要： Provided is a method that provides both spatial and temporal control of a polymer degradation process using mono- and multifunctional macromolecular monomers (“macromers”) that degrade via single- and multi-photon photolysis mechanisms over a broad range of wavelengths. The macromers can form or be incorporated into networks via covalent, non-covalent and/or ionic interactions. The spatial and temporal degradation of these networks can be controlled. More specifically, provided is a photodegradable macromer, comprising: (a) a photodegradable group; (b) a backbone structure comprising one or more repeating units that may be the same or different, which backbone structure is attached to the photodegradable group directly or through a linker; (c) one or more reactive end groups at one or more ends of the macromer; and optionally, (d) one or more therapeutic agents; and optionally (e) one or more caged groups. Also provided are polymers and networks incorporating macromers of the invention and optionally other substituents such as other polymeric structures. Also provided is a method of controlled degradation of a polymer comprising: providing a photodegradable polymer as described herein and exposing the photodegradable polymer to photoradiation of the appropriate wavelength and energy to cause one or more of the photodegradable groups to photodegrade.

摘要： Biodegradable polymer networks are provided which are useful in a variety of dental and orthopedic applications. The biodegradable polymer networks can be formed in one embodiment by polymerizing anhydride prepolymers including crosslinkable groups, such as unsaturated moieties. The anhydride prepolymers can be crosslinked, for example in a photopolymerization reaction by irradiation of the prepolymer with light in the presence of a free radical initiator. Suitable anhydride prepolymers include dianhydrides of a dicarboxylic acid and a carboxylic acid molecule comprising a crosslinkable group. For example, methacrylic acid dianhydrides of monomers or oligomers of a diacid such as sebacic acid or 1,3-bis(p-carboxyphenoxy)-hexane can be used. The anhydride prepolymers can be applied in vivo to a site where an orthopedic implant is needed, and then may be crosslinked, for example, by irradiation with U.V. light, to form a biodegradable implant such as a rods, pin or plate. The implants advantageously provide mechanical support and also are capable of slow surface degradation to permit bone ingrowth.
