A three-dimensional cell growth medium is described. The cell growth medium may comprise hydrogel particles swollen with a liquid cell growth medium to form a granular gel yield stress material which undergoes a phase transformation from a solid phase to a liquid-like phase when an applied stress exceeds the yield stress. Cells may be placed in the three-dimensional cell growth medium according to any shape or geometry, and may remain in place within the three-dimensional cell growth medium.

Growth media for three-dimensional cell culture

The present disclosure relates to compositions and methods for treatment of degenerative conditions of large weight-bearing joints, such as osteoarthritis, by intra-articular delivery of a codon-modified IL-1Ra encoding gene.

IL-1RA cDNAs

Described herein are methods and apparatus for constructing tissue replacements, such as bone replacements that may be used to repair damaged or missing segments of bone, such as may occur in wound repair or as a repair of a congenital anomaly. These methods involve a three-dimensional (3D) cell growth medium made from a yield stress material that allows cells and structures to be easily deposited and positioned.

Fabrication of autologous bone

Disclosed herein is an integrated assay system that can be used, for example, to monitor and screen cells in 3D culture. This system involves a 3D cell growth medium made from a yield stress material that allows cells to be deposited, e.g. by 3D printing, samples to be taken, and the extracellular environment manipulated.

3D micro fabrication and screening

Methods and compositions for treating symptoms of conditions such as but not limited to osteoarthritis and rheumatoid arthritis. The methods may feature direct intraarticular injection of a recombinant self-complementary adeno-associated virus (sc-rAAV) with a vector adapted to express a modified IL-1Ra peptide. The methods of the present invention may express a therapeutically effective amount of the modified IL-1Ra peptide so as to ameliorating symptoms associated with the condition being treated.
