Patents by Inventor Afshin Sohrabi

Afshin Sohrabi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cell-culture and polymer constructs
    Publication number: 20020123142
    Abstract: Cells grown on a microcarrier are separated from the microcarrier by enzymatically digesting the microcarrier. More specifically, chondrocytes may be grown on dextran microcarrier beadlets and then the beadlets digested using dextranase to separate the chondrocytes from the carrier. Cells can also be grown on chitosan microcarriers to be used for implantation. In addition, cells can be grown on polysaccharide polymers to be used as implant devices. Various polymers serve as scaffolds for cells to be used for implantation. The polymers can be used for cell culture as well as for preparing scaffolds useful for tissue replacement such as cartilage tissue.
