Embryonic and Adult Stem Cell Research - Addressing the Facts and the Issues: Home

This guide presents selected resources on background information about embryonic and adult stem cell research and related issues as well as perspectives from a variety of sources on the ethics this research.


The National Institutes of Health Guidelines for Human Stem Cell Research were published on July 7, 2009. This was in response to the March 9, 2009 Executive Order (EO) 13505 (see below), which changed the way National Institutes of Health (NIH) can support and conduct human stem cell research. The HHS Secretary, through the NIH Director, was required to review existing NIH and other widely-recognized guidelines on human stem cell research and issue new NIH guidance within 120 days of the date of the EO.

Statistics, Data and a Timeline


The National Institute of Neurological Disorders and Stroke, NINDS, operating as part of the National Institutes of Health, NINDS supports a diverse array of research on stem cells, from studies of the basic biology of stem cells in the developing and adult mammalian brain, to studies focusing on nervous system disorders such as ALS or spinal cord injury. Other examples of NINDS funded research include using iPS cells to derive dopamine-producing neurons that might alleviate symptoms in patients with Parkinson’s disease, and using ES cells to generate cerebral organoids to model Zika virus infection.
