摘要:
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.
摘要:
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.
摘要:
Disclosed are a composition and a method for inducing the de-differentiation of astrocytes into neural stem cells using Shh. The de-differentiated neural stem cells have the ability to differentiate into astrocytes, neurons, and oligodendrocytes.

Provided 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 encoding the Bmi1 protein; and b) at least one low molecular weight substance selected from the group consisting of a set of a MEK/ERK (mitogen-activated protein kinase/extracellular regulated kinase) inhibitor and a GSK (glycogen synthase kinase) inhibitor, a set of a G9a HMTase (G9a histone methyltransferase) inhibitor and a DMNT (DNA methyltransferase) inhibitor, and a histone deacetylase inhibitor. 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 reprogramming 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.
