RESUMEN
The developing countries are experiencing a shift in the population profile, faster than that experienced by developed countries, especially due to the consolidation of health practices and technological advances. These social changes also imply new socioeconomic models, able to escort social demands caused by the growth of the elderly population and the decrease in young economically active population. Several countries seek for actions that do not marginalize the elderly, and invest heavily in new technologies to ensure health access and active participation of this group in society. Stem cell research may reflect at an improvement of public health, reduction in costs of hospitalization and lead to prevention and treatment of extremely debilitating illness, like the neurodegenerative diseases. Preserving the physical and mental functional capacity is of extreme importance to ensure the active participation of elderly population in society.
