60. A method of generating bone in a patient in need thereof comprising:
-
(i) obtaining mammalian mesenchymal stem cells; (ii) producing a bone forming composition by culturing said mammalian mesenchymal stem cells in vitro on a three-dimensional marrow stromal cell derived extracellular matrix, isolating undifferentiated mammalian mesenchymal stem cells from said culture, and combining said undifferentiated mammalian mesenchymal stem cells with a transplantation vehicle; and (iii) administering said bone forming composition to said patient; wherein said extracellular matrix comprises type I collagen, type II collagen, type V collagen, syndecan-1, fibronectin, decorin, biglycan, perlecan, and laminin. - View Dependent Claims (61, 62, 63, 64, 65, 66)
