Abstract: Disclosed herein are compositions, devices, methods, processes, and systems for culturing of large quantities of mammalian cells in suspension culture. Also disclosed are unique and surprising cell populations derived from the disclosed methods, processes, and systems. In many embodiments, the cells are cultured in suspension in liquid culture media that is agitated to maintain the cells in suspension, and agitation increases to maintain cells in suspension while growing and dividing to create cell spheres. The disclosed devices, methods, processes, and systems are useful in tailoring characteristics of the resulting cells based on characteristics of donor subject/initial cells. The disclosed cell populations are useful in treating subjects with cell based therapies in need thereof for various diseases and conditions.

Abstract: Disclosed 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 one or more genes in a cell using said compositions, introducing a CRISPR-Cas system into a cell comprising one or more vectors comprising said compositions, including site-specific DNA cleavage in a cell, and treating a subject having lower back pain, and lower back pain cause by degenerative disc disease using the compositions disclosed herein.
