Patent ID: 8129186

Claim:
A method for enhancing growth, survival and/or maintenance of function of non-choroid plexus (non-CP), non-neuronal cells in long term or short term culture, wherein the non-CP, non-neuronal cells are islet cells, fibroblasts or Human Umbilical Vascular Endothelial Cells (HUVEC) cells, said method comprising the steps of: (a) providing a choroid plexus (CP) preparation, wherein the preparation comprises: 1) a CP cell population capable of producing one or more factors that support survival and growth of non-CP, non-neuronal cells; and/or 2) a CP cell culture capable of producing one or more factors that support survival and growth of non-CP, non-neuronal cells; and/or 3) CP conditioned media from a) or b) comprising one or more factors that support survival and growth of non-CP, non-neuronal cells, alone or in combination with a culture medium suitable for growth survival and/or maintenance of function of non-CP, non-neuronal cells to produce a.an enhanced medium; and (b) culturing the non-CP, non-neuronal cells in the enhanced medium of step (a).
