Cell delivery system comprising a fibrous matrix and cells

Patent Number: 7,323,190

The current patent covers the delivery of cells using a matrix that is fibrous and the fibers are between 10 nanometers to 1 micrometer in diameter. The fibers are made in such a manner so that they are in contact with the cells. In some of the claims the fibers are comprised of polymers, one type of polymer covered is a linear aliphatic polyester. A specific type of linear aliphatic polyester is made of polyglycolide or a copolymer poly(glycolide-co-lactide).

This patent is useful for localization of viable cells, including stem cells, and possesses a certain degree of "controlled release" that make the invention suitable for delivery of a variety of cell types.

One potential application of this invention would be the delivery of cord blood cells to burn wounds. Since this invention was created in part with support from the Department of Defense, this may indeed be one of the things that it will be used for.
