    摘要: The invention provides a method for the controlled assembly of layered silk fibroin coatings using aqueous silk fibroin material. The methods described herein can be used to coat substrates of any material, shape, or size. Importantly, the described methods enable control of the biomaterial surface Chemistry, thickness, morphology and structure using layered thin film coatings, or bulk coatings. Furthermore, the methods can be performed in all water and do not require intensive chemical processing enabling controlled entrapment of labile molecules such as, drugs, cytokines, and even cells or viruses to generate functional coatings that can be used in a variety of applications.

    摘要: The inventions provided herein generally relate to compositions and methods for controlling response of immune cells to at least one stimulus or condition (e.g., but not limited to, tissue damage, an implantable device and/or a cytokine) in vitro or in vivo. The compositions described herein comprise a biomaterial (e.g., a silk fibroin-based matrix) comprising at least one immune cell-modulating agent in an effective amount sufficient to selectively alter activation state of at least one type of immune cells (e.g., but not limited to macrophages and dendritic cells). Accordingly, in some embodiments, the compositions and methods described herein can be used to selectively skew macrophages to M1 phenotype and/or M2 phenotype and thereby control the inflammatory and/or regenerative responses of the macrophages, e.g., to repair and/or regenerate a target tissue.

    摘要: The inventions provided herein relate to compositions, methods, delivery devices and kits for repairing or augmenting a tissue in a subject. The compositions described herein are injectable such that they can be placed in a tissue to be treated with a minimally-invasive procedure (e.g., by injection) and/or be molded flexibly into a tissue void of any shape and/or size. In some embodiments, the composition described herein comprises a plurality of silk fibroin particles, which can retain their original volume within the tissue for a period of time. The compositions can be used as a filler to replace a tissue void, e.g., for tissue repair and/or augmentation, or as a scaffold to support tissue regeneration and/or reconstruction. In some embodiments, the compositions described herein can be used for soft tissue repair or augmentation.
