Abstract
Methods and compositions for repairing tissue. Certain embodiments of the invention involve transdifferentiation of cells in a manner not heretofore provided for. One embodiment of the invention features methods for producing stem cells. These methods can involve exposing cells (e.g., human fibroblasts) to a processed or activated egg extract (e.g., activated egg extract); and culturing the cells for a period of time to become stem cells. A cell culture can be performed in two or three dimensions, so that organ tissue or whole organs may be produced, e.g., for transplantation. Another embodiment of the invention features methods for promoting wound healing by using signaling complexes.
