  • Engineered extracellular matrices control stem cell behavior
    Patent number: 9315778
    Abstract: A composition for culturing stem cells is provided. The composition comprises an engineered purified collagen based matrix that has been formed under controlled conditions to have the desired microstructure and mechanical properties. The engineered purified collagen based matrix compositions of the present invention can be used alone or in combination with cells as a tissue graft construct to enhance the repair of damaged or diseased tissues.
    Type: Grant
    Filed: September 19, 2011
    Date of Patent: April 19, 2016
    Assignee: Purdue Research Foundation
    Inventors: Sherry L. Voytik-Harbin, Beverly Z. Waisner
