Stem Cell Research
Stem cells are master cells in the body that can turn into many different types of specialized cells. They have the ability to divide for an indefinite period of time. Other cells cannot do this. CMDA provides up-to-date information on the legislative, ethical and medical aspects of stem cell research.

A recent innovation in creating model systems for studies of physiology and development has been the construction of organoids. These three-dimensional cellular structures resemble miniature organs in terms of functionality, and they can even be used to model development and differentiation and disease, as well as drug development. In this week’s blog post, Dr. David Prentice discusses the ethical implications of this new innovation.
Some scientists have said one reason they don’t consult bioethicists or think about the ethical implications of their research is because ethicists usually say “no” to new technologies, or that ethics is arbitrary. But what they are really avoiding is the necessity of setting rational limits on science, thinking they can thereby avoid any limits on their work.
An increasing number of bioethical challenges now exist in the realm of medicine and bioscience, and these new twists and paths often draw our focus and concerns. But arming ourselves to meet these challenges sometimes overshadows the positive wonders and results from ethical pathways. In this week’s blog post, Dr. David Prentice helps to refresh us with some of the good news regarding patient therapies with adult stem cells.
Does science trump ethics? Do the ends justify the means? Should some trafficking in human body parts be countenanced in society, because of potential or speculative cures? These are the questions raised in regards to the issue of fetal tissue research, in particular using fetal tissue obtained from induced abortion.
Is a farm animal mixed with a human really a possibility in our world? The National Institutes of Health is proposing to make human-animal chimeras a reality by loosening current prohibitions. Dr. David Prentice explores this issue and addresses the ethical ramifications of this research.
There has been a spate of disappointing news lately, and new challenges and concerns for healthcare professionals seem to appear weekly. But we at times need to take hope from good news and be refreshed. Dr. David Prentice shares some of the positive developments coming out of stem cell research.
