Abstract: A method for inducing reprogramming of neural stem cells from urine cells by introducing mRNAs of reprogramming factors Oct4, Sox2, Klf4, and Glis1 is disclosed. A composition for the prevention or treatment of neurological damage diseases with the neural stem cells induced by the method as an active ingredient is disclosed.

Abstract: Disclosed is a composition for reprogramming somatic cells to generate embryonic stem cell-like cells, comprising: a) a Bmi1 (B cell-specific Moloney murine leukemia virus integration site 1) protein or a nucleic acid molecule coding for Bmi1; and b) an Oct4 protein or a nucleic acid molecule coding for Oct4. Also, a method is provided for reprogramming somatic cells to generate embryonic stem cell-like cells using the composition. In addition to reducing the number of the genetic factors conventionally needed, the composition and method allow the generation of pluripotent embryonic stem cell-like cells which have high potential in the cell therapy of various diseases.

Abstract: The present invention relates to a culture medium for the fetus-derived mesenchymal stem cells in amniotic fluid. More particularly, the present invention relates to a composition for improving skin conditions, comprising the culture medium of fetus-derived mesenchymal stem cells in amniotic fluid as an active ingredient, in which the skin conditions to be improved include whitening, wrinkles, skin damages caused by UV rays or skin lifting. Further, the present invention relates to a method for preparing the composition, comprising the steps of culturing the fetus-derived mesenchymal stem cells in amniotic fluid; and collecting the culture medium.
