Abstract
There is disclosed a method of combining mesenchymal stem cells (MSCs) with a bone substrate. In an embodiment, the method includes obtaining tissue having MSCs together with unwanted cells. The tissue is digested to form a cell suspension having MSCs and unwanted cells. The cell suspension is added to the substrate. The substrate is cultured to allow the MSCs to adhere. The substrate is rinsed to remove unwanted cells. In various embodiments, the tissue is adipose tissue, muscle tissue, or bone marrow tissue. In an embodiment, there is disclosed an allograft product including a combination of MSCs with a bone substrate in which the combination is manufactured by culturing MSCs disposed on the substrate for a period of time to allow the MSCs to adhere to the substrate, and then rinsing the substrate to remove unwanted cells from the substrate. Other embodiments are also disclosed.
