Abstract: The present invention relates to stem cells in which a gene that activates signaling is introduced and to a method for proliferating the stem cells. More specifically, the invention relates to a method of significantly increasing the ability of stem cells to proliferate, either by transfecting stem cells with the Notch intracellular domain (NICD) to activate the Notch signaling pathway, or by transfecting stem cells with the c-MET gene and treating the transfected stem cells with the HGF ligand protein to activate the c-MET/HGF signaling pathway. According to the present invention, as a result of activating the Notch signaling pathway or the c-MET/HGF signaling pathway, stem cells having an excellent ability to proliferate can be produced in large amounts. Particularly, since neural stem cells which have been difficult to culture in vitro can be proliferated in large amounts, thus the neural stem cells will be more useful for the preparation of cell therapeutic agents for treating cranial nerve diseases.

Abstract: Disclosed is a composition for the prophylaxis or therapy of intraventricular hemorrhage in preterm infants comprising mensenchymal stem cells. Functioning to prevent ventricular dilatation and reduce the level of inflammatory cytokines in cerebrospinal fluid, the composition comprising mesenchymal stem cells is advantageously useful for the prophylaxis or therapy of intraventricular hemorrhage in preterm infants. Accordingly, the composition is effectively preventive of hydrocephalus which occurs subsequent to intraventricular hemorrhage. In addition, the composition makes not only a histological and biochemical recuperation in the intraventricular hemorrhage-injured brain, but also significantly improves sensory motor functions. Mesenchymal stem cells can be used as an effective therapeutic agent because they are less prone to induce immune rejection responses and are highly likely to secrete proliferative, differentiative, and regulatory factors.
