Abstract: A method is used for preparing a product for use in repairing a lesion or defect at a tissue site in a human or animal patient body. The method includes obtaining tissue from a donor human or animal body and freezing the obtained tissue. The method further includes pulverizing the frozen tissue and suspending the pulverized tissue in a fluid. The method further includes homogenizing the tissue suspension and precipitating tissue particles from the homogenized tissue suspension. The method further includes re-suspending the precipitated tissue particles and lyophilizing the tissue re-suspension to provide the product to be used in repairing the lesion or defect.

Abstract: Described herein are compositions and methods for treatment and prevention of low back pain. The compositions include vectors comprising nucleotide sequences encoding one or more CRISPR-Cas system guide RNAs and a RNA-directed nuclease. The methods include modulating expression of a gene in a cell using said compositions, introducing a CRISPR-Cas system into a cell comprising one or more vectors comprising said compositions, inducing site-specific DNA cleavage in a cell, and treating a subject having lower back pain, and lower back pain caused by degenerative disc disease using the compositions disclosed herein.

Abstract: A method has been developed for repairing a cartilage lesion. The method includes bringing a three-dimensional porous substrate into direct contact with prepared bone. The three-dimensional porous substrate is fixedly coupled to a three-dimensional scaffold such that the substrate supports the scaffold. The three-dimensional porous substrate comprises at least three layers of woven fibers. The substrate is configured to be inserted into bone tissue including cartilage lesions such that the substrate and the scaffold replace the bone tissue including the cartilage lesions. The substrate and scaffold are further configured such that after the substrate and the scaffold have replaced the bone tissue including the cartilage lesions, the substrate and scaffold promote growth and integration of new bone tissue into the implant.
