1. Cell Loss
Our liver, kidneys and other organs keep a fair number of cells in reserve; still, over time, cell loss may impair their functioning.
De Grey’s fix: Engineer embryonic stem cells to create healthy new versions of every type of body cell. Introduce the stem cells into the body to rejuvenate diseased or flagging tissues. The mechanism to deliver the various cell types to all the right places has yet to be developed.
