Scientists can 3D print human heart tissue now

Long term, the goal of 3D bioprinting is to be able to 3D print fully functioning organs which can be used to replace the failing biological organs of humans in need of a transplant. That may still be years off, but Chicago-based biotech startup Biolife4D this week announced a major new milestone: Its ability to bioprint human cardiac tissue.

The scientific landmark followed shortly after the company opened a new research facility in Houston. It involved the printing of a human cardiac patch, containing multiple cell types which make up the human heart. It could one day be used to help treat patients who have suffered acute heart failure in order to restore lost myocardial contractility, the ability of the heart to generate force for pumping blood around the body.

“The cardiac patch that we printed demonstrated two major advancements,” Steven Morris, CEO of Biolife4D, told Digital Trends. “First, it demonstrated Biolife4D’s ability to take a patient’s own blood cells, reprogram them back into stem cells, reprogram them again to make the different type of cells which we need to 3D bioengineer our human heart viable for transplant, and then successfully 3D bioprint with those cells to make living human heart tissue.

The importance of commenting

The ABCs of Biotech for Christians - Thirteenth in a series - L is for Lab

In early 2017 the the U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) published a draft of Proposed Rules and invited public comment. Their Notice of Intent was to prepare an environmental impact statement on Biotechnology Regulations.

That 32-page document addressed the need to regulate the import, interstate movement and environmental release of certain genetically engineered organisms (basically). Though the GE plants are for the purpose of introducing new or improved types of food, or affecting crop yield or resistance to disease, or meeting other goals, they could have detrimental effects so oversight is needed.

That document states:

To date, APHIS has issued more than 18,000 authorizations for the environmental release of GE organisms in multiple sites, primarily for research and development of improved crop varieties for agriculture. Additionally, APHIS has issued more than 12,000 authorizations for the importation of GE organisms, and nearly 12,000 authorizations for the interstate movement of GE organisms. APHIS has, to date, denied slightly more than 1,500 requests for permits or notifications, many of which were denied because APHIS ultimately decided the requests lacked sufficient information on which to base an Agency decision.

Biotech labs are busy places. Biotech is big business and hopeful investors watch its developments religiously. So do groups that are concerned about the environment and health safety.

After the APHIS document was posted in early 2017 and open for public comments, it was withdrawn in early November 2017 to go back to the drawing board. The commenters brought up too many reasons why the proposed rules needed work. Untimately, a new commenting period ended in July 2018.

APHIS of the USDA is only one government agency concerned with what biotech labs are inventing. The FDA (Food and Drug Administration), EPA (Environmental Protection Agency), OSHA (Occupational Health and Safety) and probably others are involved with oversight of biotech products and developments.

Whether approving the release of the first GE mosquito whose mission was to decimate its fellow mosquitoes, or permitting genetically modified livestock that produce human milk, or letting people try a new drug even though its risks are not fully understood, in the USA, biotech must answer to the regulators.

Laboratory safety is carefully prescribed and guarded but no one can prevent scientists from tinkering with the genomes of living organisms. The inventions of biotechnology are changing our definition and experience of life everyday. As Christians, what are the questions we need to ask relating to GE? What should our comments be? A comment can be a powerful lever in a democratic society.

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.
