1. A method for inhibiting teratoma formation or growth comprising administering a composition comprising TIMP-1 or TIMP-2 as an active ingredient to a subject in need thereof,
wherein the composition is produced by a process comprising steps of:

(b) obtaining TIMP-1 or TIMP-2 in conditioned medium by culturing the immortalized neural stem cells in a non-inducing medium.
