Embryonic Stem Cell Research Oversight Committees
The National Academies called for the establishment of Embryonic Stem Cell Research Oversight (ESCRO) Committees in its 2005 "Guidelines for Human Embryonic Stem Cell Research" to manage the ethical and legal concerns in human embryonic stem cell research. Because of the complexity and novelty of many of the issues involved in that research, the Guidelines committee believes that all research institutions engaged in human embryonic stem cell research should create and maintain these committees at the local level.
2004 California Proposition 71
Human embryonic stem cell research became a public issue in 1998 when two teams of scientists developed "methods for culturing cell lines derived, respectively, from: (1) cells taken from the inner cell mass of early embryos, and (2) the gonadal ridges of aborted fetuses". Since then, this type of research has sparked intense controversy in the United States.
