Abstract: A novel use of periostin, and more particularly a composition for inducing the migration of neural stem cells, which contains periostin or a periostin-secreting cell as an active ingredient, based on the discovery of a novel function of periostin that induces the migration of neural stem cells. Periostin induces the migration of neural stem cells, and thus the composition for inducing the migration of neural stem cells, which contains periostin or periostin-secreting cells as an active ingredient, can be used in various applications based on neural stem cells. A pharmaceutical composition containing suicide gene-expressing neural stem cells and periostin allows the neural stem cells to effectively migrate to tumor tissues, and thus can be used as a cell therapeutic agent for treating cancer. Also, the pharmaceutical composition containing neural stem cells and periostin has improved effects on the stimulation of regeneration of nerve cells and the treatment of neural diseases.

Abstract: Disclosed is an indoor unit for an air conditioner to solve drain problem of condensed water. The indoor unit includes: a lower frame provided with a suction inlet through which exterior air is inhaled; a middle frame spaced upward apart from the lower frame by a predetermined distance; an indoor heat exchanger for performing heat exchange; and a drain pan for collecting and draining condensed water generated in the indoor heat exchanger, the drain pan being mounted selectively on the lower frame or the middle frame.

Abstract: Disclosed is an indoor unit for an air conditioner to improve convenience in carriage and installation. The indoor unit includes: a heat exchanger for performing heat exchange; a drain pan for draining condensed water generated while the heat exchanger operates; a connection tube formed at one side of the heat exchanger, for guiding flow of refrigerant; and a tube coupling part opened at both ends of the connection tube, for allowing the refrigerant to communicate with one of the both opened ends of the connection tube.
