Abstract:
An isolated, acellular biosynthetic cartilaginous matrix substantially devoid of synthetic biodegradable scaffold structure is provided. Through a method with the steps of a) contacting in vitro a population of chondrogenic cells with a synthetic biodegradable scaffold; b) culturing in vitro for a period of time said chondrogenic cells within said synthetic biodegradable scaffold so that the chondrogenic cells produce a biosynthetic cartilaginous matrix; c) substantially removing any antigen derived from said chondrogenic cells a matrix suitable of implantation into a living individual mammal, such as a human being is obtained.

Abstract:
The present invention provides for a method for tissue engineering by cell implantation that involves the use of a scaffold in situ at the site of a defect, where the therapeutic cells are fixed in place into the scaffold only once the scaffold is inserted at the site of the tissue defect, thereby locking not only the cells to the scaffold, but also the scaffold to the tissue defect. The invention also provides a kit of parts suitable for performing the method of the invention.

Abstract:
The present application discloses that incorporation of dermatan sulfate and/or HA in composite scaffolds of certain polymers gives rise to a chondrogenic effect on chondrocytes resulting in formation of cartilage that resembles the natural ECM. This effect with dermatan sulfate as the primary additive has not previously been seen. The composites are formed by incorporation of dermatan sulfate finely dispersed particles optionally nanoparticles or as molecular dissolutions in a polymer matrix with no bonding between the DS and the matrix, providing the DS to the chondrocytes in an accessible non-crosslinked form.
Abstract:
The present invention provides for a composition, for augmentation and regeneration of living tissue in a subject, comprising a population of porous microparticles of a biodegradable polymer, one or more mammalian cell populations, and optionally, a biocompatible adhesive.
