Same-sex mouse parents give birth via gene editing

IMG_9461

Scientists delivered pups with genetic material from two moms and two dads. But only pups with two moms survived to have babies themselves.

BIRDS DO IT, bees do it—even laboratory mice do it. But with science in the mix, actually creating new life may not always require a male and a female.

Using gene editing and stem cells, researchers in China have helped mice of the same sex bear pups. While this feat has been accomplished before with mouse moms, the new study marks the first time that pups from pairs of male mice were also carried to full term.

The technology is far from ready for the leap to humans. Though mice pups born from two females appeared healthy and bore their own young, pups with two papas died soon after birth. Of the 12 born, just two survived more than 48 hours.

Scientists discover a way to prevent stem cell loss and improve tissue regeneration

Stem Cells and Aging

The stem cells found within the average adult human are capable of restoring dying cells while also fixing damaged tissue. Nothing is safe from the aging process, though, and as we get older we begin to lose the very same stem cells that once kept our bodies in functional condition. But there could be a way around that: new stem cell research has revealed a nutrient sensing pathway called TOR can be subdued in order to prevent such loses. TOR plays a key role in the aging process and is largely responsible for the loss of stem cells in the human body.

French researchers restore the youth of cells taken from 100 year old people

Scientists in France were able to restore the youth of cells taken from people 100 years of age and older. They reprogrammed them to stem cells stage, demonstrating that aging is in fact reversible.

Human Longevity wants to make 100 the new 60 and have healthier people living longer

old-men-and-bike

Human Longevity doesn’t aim to extend human life so much as to help keep people healthy as they get older.

Dr. Robert Hariri, who once worked directing cell therapy operations at Celgene, a biopharmaceutical company is teaming up with Craig Venter, and engineer Dr. Peter Diamandis, chairman of the X Prize Foundation. Karen Nelson, who headed the J. Craig Venter Institute (JCVI), will lead the microbiome team. They launched a new company called Human Longevity Inc.

Capsules of stem cells placed on injured bones works to heal the bones

broken bone

Materials science may be a big help in healing broken bones.

How do medical researchers best cultivate certain kinds of cells and spur them to function in the body? The details are still being worked out. Materials science may be a big help, according to University of Rochester researchers.

Scientists discover way to regenerate teeth with lasers

Scientists use low powered laser to grow teeth.

Scientists have used a low powered laser to activate and direct stem cells to grow teeth.  It looks as if they did it right in the mouth (of a couple of species)!  That’s a disruptive innovation compared to the way stem cells are typically grown and developed outside the body.

Researchers develop new method to grow human skin from stem cells that replicates the real thing

The method could viably produce enough skin samples to be used commercially for drug and cosmetics testing.

The use of animal testing for medical research than for cosmetics testing is much easier to defend.  Yet many cosmetics companies continue to test on animals to ensure that their products don’t produce negative outcomes for their human customers.

Scientists one step away from cloning adult humans

stemcells

It might soon be possible to grow human body parts in a lab, even from older adults’ stem cells.

For the first time ever human cloning has been used to create stem cells for adults in a breakthrough which could lead to tissue and organs being regrown. Scientists have turned the skin cells of a 75-year-ol man into stem cells, which can grow into any type of tissue in the body.
