Abstract: The subject invention concerns novel and translatable materials and methods for expansion of stem cells, such as mesenchymal stem cells (MSC), that significantly improve translational success of the cells in the treatment of various conditions, such as stroke. The subject invention utilizes cell self-aggregation as a non-genetic means to enhance their therapeutic potency in a microcarrier bioreactor. The subject invention integrates a cell aggregation process in a scalable bioreactor system. In one embodiment of the method, thermally responsive microcarriers (TRMs) are utilized in conjunction with a bioreactor system. Cells are cultured in a container or vessel in the presence of the TRMs wherein cells adhere to the surface of the TRMs. Once cells are adhered to the TRMs they can be cultured at a suitable temperature for cell growth and expansion, e.g., at about 37° C.
