From age 20, human brains begin slowly shrinking, eventually leading to loss of cognitive and physical function in old age. Neural stem cell technology could heal and reverse the damage, returning quality of life to a vast, aging population. In her bittersweet essay, science writer Linda Marsa explains just how close neural stem cell research is to reversing many of the diseases of old age. Marsa explains how scientists have overcome ethical issues and immune system rejection, and cites successful studies to show the promise this research holds. getAbstract recommends her observations to anyone looking for some good news about the future of aging.
In this summary, you will learn
- How stem cell research has evolved since the 1990s;
- Why the eyes, brain and spinal cord are some of the most promising areas for research; and
- How stem cell therapies could reverse many of the effects of old age.
