PHARMACEUTICAL COMPOSITION FOR THE PREVENTION OR TREATMENT OF A LUNG DISEASE COMPRISING MESENCHYMAL STEM CELLS HAVING IMPROVED PROLIFERATION AND DIFFERENTIATION CAPACITY

摘要

Provided in the present invention are a pharmaceutical composition for preventing or treating lung diseases, comprising mesenchymal stem cells having improved proliferation and differentiation capacity, whether to express a specific cell marker, and a method for obtaining mesenchymal stem cells having improved proliferation and differentiation capacity, on the basis of the expression of the specific cell marker. According to the method of the present invention, the mesenchymal stem cells having excellent proliferation and differentiation capacity can be obtained in a convenient manner, on the basis of the expression of CD26, CD49f, CD146, and EGFR from the mesenchymal stem cells obtained from various sources. The obtained mesenchymal stem cells can be efficiently used for preventing or treating lung disease, comprising pulmonary emphysema.
