  • Publication number: 20110150899
    Abstract: The present invention relates to a composition containing an extracellular matrix for controlling aging and a method for controlling aging by using the same. The composition for controlling aging and the method for controlling aging have an effect for recovering the biological function of the aged aging cell, and the amount of the expression of the integrin alpha V that is a cell membrane protein and is reduced if aging is again increased in the aging cell recovered by the young extracellular matrix. However, when the amount of expression of the integrin alpha V is artificially decreased by using siRNA and antibody, the aging cell is not recovered by the extracellular matrix extracted from the young cell.
