For example, adult stem cells, amniotic stem cells, and induced pluripotent stem cells do not involve creating, using, or destroying human embryos, and thus are minimally, if at all, controversial. Many less controversial sources of acquiring stem cells include using cells from the umbilical cord, breast milk, and bone marrow , which are not ...
Haruko Obokata claimed that STAP cells were produced by exposing CD45 + murine spleen cells to certain stresses including an acidic medium with a pH of 5.7 for half an hour. [6] [7] Following this treatment, the cells were verified to be pluripotent by observing increasing levels of Oct-4 (a transcription factor expressed in embryonic stem cells) over the following week using an Oct4-GFP ...
Hwang's team reported another successful cloning of human cells in the 17 June 2005 issue of Science, in this case, embryonic stem cells derived from skin cells. [27] Their study claimed the creation of 11 different stem cell lines that were the exact match of DNA in people having a variety of diseases.
Stem-cell therapy has become controversial following developments such as the ability of scientists to isolate and culture embryonic stem cells, to create stem cells using somatic cell nuclear transfer, and their use of techniques to create induced pluripotent stem cells. This controversy is often related to abortion politics and human cloning.
Haruko Obokata (小保方 晴子, Obokata Haruko, born 1983) is a former stem-cell biologist and research unit leader at Japan's Laboratory for Cellular Reprogramming, Riken Center for Developmental Biology.
A Lancet review on Handling of Scientific Misconduct in Scandinavian countries gave examples of policy definitions. In Denmark, scientific misconduct is defined as "intention[al] negligence leading to fabrication of the scientific message or a false credit or emphasis given to a scientist", and in Sweden as "intention[al] distortion of the ...
The Republicans largely oppose embryonic stem cell research in favor of adult stem cell research which has already produced cures and treatments for cancer and paralysis for example, but there are some high-profile exceptions who offer qualified support for some embryonic stem cell research. [5]
