Fasting boosts stem cells’ regenerative capacity

As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine.

This age-related loss of stem cell function can be reversed by a 24-hour fast, according to a new study from MIT biologists. The researchers found that fasting dramatically improves stem cells’ ability to regenerate, in both aged and young mice.

In fasting mice, cells begin breaking down fatty acids instead of glucose, a change that stimulates the stem cells to become more regenerative. The researchers found that they could also boost regeneration with a molecule that activates the same metabolic switch. Such an intervention could potentially help older people recovering from GI infections or cancer patients undergoing chemotherapy, the researchers say. Read more.

Japan’s Chimera Embryo Regulations Raise Concerns

Japanese regulators have effectively given the green light to research involving human-animal chimera embryos, which are created by implanting human pluripotent stem cells into animals in early development. The revised guidelines, issued in early March, lift a previous requirement to terminate such embryos after 14 days.

The revisions now pave the way for Japanese scientists to study how to grow human organs in animals as an alternative to organ transplantation, and to produce better models to study human development and disease.

However, they also raise some ethical concerns, as a group of Japanese bioethicists at the Kyoto University note in a letter published today (April 4) in Cell Stem Cell. For instance, the guidelines would allow researchers to create chimeras with human cells populating animal brains—something that concerns the Japanese public. They also don’t explicitly prohibit chimera embryos made from human and nonhuman primate cells, which could take experiments into ethically uncharted territory. Read more.

...and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind ... the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind ...the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. -Genesis 1

Flesh and Bone and The Protestant Conscience is an e-book on Amazon.com. It is 99¢ and in the Amazon lending library as well. It is also available here in PDF format. The book description follows.

Would you let your conscience be your guide?

Does God care if the skin and bone of the dead are passed along to the living for medical uses? Is organ donation OK with God? Should you sign a Living Will?

Did you know that dead organ donors are often anesthetized before their organs are removed? Do you know the current definition of death? The conscience cannot function without facts.

As we ponder the ethics of in vitro fertilization, stem cell research and man-made chimeras, our thoughts trail off. How then should we live? (Ez 33:10)

How should a Christian think about euthanasia by starvation when doctors and the state attorney general all agree it is time to withhold feeding from a brain injured patient? Some things are family matters, but someday it may be our family.

Here is a small book to help you think about whether you want to sign your driver's license, donate a kidney, cremate your loved one, and many other practical questions that may arise in the course of your healthcare decisions or watch over others.

It offers a special focus on the doctrine of the Resurrection that is related to such decisions. Sunday School classes and Bible Study groups could use this book to facilitate discussion about the issues covered.
