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.

The body of a Korean man who died in Mexico of “natural causes” has been flown home with missing organs, prompting his widow to speak out.

The 35-year-old (known only as Mr Kim) leaves behind two children and a wife, who claims there was nothing natural about her husband’s cause of death…

Her fears of a cover-up were amplified when she demanded a second autopsy be performed on January 21 by the Korean National Forensic Service.

A forensic scientist told her there were signs of external injury and bruising on her husband’s body. He was also missing his brain and stomach. The NFS could not determine the cause of his death due to the missing organs.

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.
