Abstract
The invention relates to the isolation and use of pre-chondrocytes from the umbilical cord, specifically from Wharton's jelly, that give rise to chondrocytes which produce cartilage. The isolated pre-chondrocytes, or the chondrocytes to which they give rise, can be mitotically expanded in culture and used in the production of new cartilage tissue for therapeutic use. "Banks" of pre-chondrocytes or chondrocytes can be stored frozen, and thawed and used to produce new cartilage tissue as needed.
Claims6
A method of isolating a pre-chondrocyte from Wharton's jelly of the umbilical cord comprising, collecting Wharton's jelly comprising pre-chondrocytes from an umbilical cord, culturing the Wharton's jelly in vitro under conditions wherein said pre-chondrocytes proliferate, and isolating the pre-chondrocyte therefrom.
A method of isolating a chondrocyte from Wharton's jelly of the umbilical cord comprising, collecting Wharton's jelly comprising pre-chondrocytes from an umbilical cord, culturing the Wharton's jelly in vitro under conditions wherein said pre-chondrocytes proliferate, isolating the pre-chondrocytes therefrom, culturing the pre-chondrocytes under conditions that induce the production of chondrocytes capable of producing cartilage tissue, and isolating the chondrocyte.
