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.
Somatic cell nuclear transfer
Proposals to use nucleus transfer techniques in human stem cell research raise a set of concerns beyond the moral status of any created embryo. These have led to some individuals and organizations who are "not" opposed to human embryonic stem cell research to be concerned about, or opposed to, SCNT research.
