Stem Cell Quick Reference

Naturally derived materials and acellular tissue matrices have the potential advantage of biologic recognition. McHugh and Kiessling advance a similar argument. With the actual rate of advancement in cloning, one cannot exclude a future in which the safety and efficiency of SCNT will be comparable or superior to that of IVF or even sexual reproduction.

Levickand Ahlberg and Brighouse have also advanced this view. The matrices slowly degrade upon implantation, and are replaced and remodeled by ECM proteins synthesized and secreted by transplanted or ingrowing cells.

Furthermore, the biomaterial should provide an environment in which appropriate regulation of cell behavior e. However, for many patients with extensive end-stage organ failure, a tissue biopsy may not yield enough normal cells for expansion and transplantation.

Some authors have reasoned that if, in the future, cloning becomes safer than sexual reproduction, we should even make it our reproductive method of choice Fletcher ; HarrisCh.

Brock and Buchanan et al. The in vivo resorption rate can be regulated by controlling the density of the implant and the extent of intermolecular cross-linking.

Presumably this would make it even easier for the clone to view herself as distinct from the progenitor than if she had been genetically identical to someone her same age.

The donor nucleus came from a child with a rare genetic disorder. But suppose some people create a clone for instrumental reasons, for example, as a stem cell donor for a sick sibling.

A remaining question is, then, whether those who condemn cloning because of its experimental nature should continue to condemn it morally and legally.

Embryonic stem cells genetically identical to the patient could provide valuable in vitro models to study disease, especially where animal models are not available, where the research cannot be done in patients themselves because it would be too invasive, or where there are too few patients to work with as in the case of rare genetic diseases.

However, since I have already mentioned this concern, I will, in the remainder of this entry, focus on other arguments 3. The general ethical rule reflected in regulations concerning altruistic donation, namely that there must be a high chance of a good outcome for the patient, is violated in the case of oocyte donation for cloning research George Read on to learn where different types of stem cells come from, what their potential is for use in therapy, and why some types of stem cells are shrouded in controversy.

Tissue Engineering, Stem Cells, and Cloning: Opportunities for Regenerative Medicine

Article 11 of this Declaration states: According to Brock, it is not clear why this should be different in the case of cloning. Macintosh—21 has warned that by expressing certain concerns about cloning one may actually reinforce certain prejudices and misguided stereotypes about clones.

Pencehas argued that having high expectations, even if based on false beliefs, is not necessarily a bad thing. By studying the privileged sites for committed precursor cells in specific organs, as well as exploring the conditions that promote differentiation, one may be able to overcome the obstacles that could lead to cell expansion in vitro.

Hansen, J.E.,“Embryonic stem cell production through therapeutic cloning has fewer ethical problems than stem cell harvest from surplus IVF embryos,” Journal of Medical Ethics, 28(2): 86–8. Led by Dr. Timothy Peace, we have been performing stem cell therapy for over Therapeutic cloning is a method for creating patient-specific embryonic stem (ES) cells.

Potential as therapy. Therapeutic cloning can, in theory, generate ES cells with the potential to become any type of cell in the body.
