METHOD FOR PROLIFERATING STEM CELLS BY ACTIVATING NOTCH SIGNALING

摘要

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 by transfecting stem cells with the Notch intracellular domain (NICD) to activate the Notch signaling pathway. According to the present invention, as a result of activating the Notch signaling pathway, stern 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.
