The ethical issues on stem cell research and the three methods used to gather stem cells

However, the technique may disrupt the DNA in the new stem cells, resulting in damaged and cancerous tissue. Most cells in the body are differentiated cells. Neither the donation of materials to derive iPS cells nor their derivation raises special ethical issues.

arguments for stem cell research

There are, at least in theory, various sources of hES cells. Researchers continue to study how to avoid these possible complications. The risks of harm and the potential benefits to society from the development of generalizable knowledge and, sometimes, potential direct benefit to patient-subjects must be weighed and balanced at each stage of the research.

These materials could be deidentified and then used by researchers. Some people argue that consent from gamete donors is not required for embryo research because they have ceded their right to direct further usage of their gametes to the artificial reproductive technology ART patients.

Such payments, which were carried out before donation for research was actually considered, are not an inducement for hESC research However, more research is needed to help understand the potential uses of amniotic fluid stem cells.

Personnel who have access to these identifiers might receive additional background checks, interviews, and training.

The principle of proportionality, the slippery slope, and the principle of subsidiarity enter the debate again, but in a slightly different way. The egg is allowed to divide and soon forms a blastocyst.

This process creates a line of stem cells that is genetically identical to the donor's cells — in essence, a clone.
