摘要:
A growth factor delivery scaffold combines a heparin/fibrin-based delivery system (HBDS) with a backbone based on polymer nanofibers for tissue (e.g., tendon and ligament) repair. The scaffold has improved surgical handling properties compared to the gelatinous consistency of the prior art HBDS system and retains the capability for delivering mesenchymal cells and controlling the release of growth factors. One application for the scaffold is mesenchymal stem cell (MSC) therapy for flexor tendon repair. The scaffold can deliver growth factors in a sustained manner, can be implanted for flexor tendon repair, is biocompatible, and is not cytotoxic. The growth factor delivery scaffold may also be used in the surgical repair of an injury to bone, muscle, cartilage, or other tissues.

摘要:
A computer-implemented method for determining a quantification of the deformation of the sample is implemented using a computer device in communication with a memory. The method includes receiving, by the computer device, a first image of the sample and a second image of the sample. The method also includes registering the first image to the second image using a warping function. The warping function maps a plurality of pixels in the first image to a plurality of pixels in the second image. A first displacement field for the sample is determined based on the warping function, where the first displacement field includes at least a portion of the warping function. A first quantification of the deformation of the sample is determined based at least in part on the displacement field.

摘要:
Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF/CCN2, or cells.
