The diversity of medical conditions in crowdfunding campaigns for stem cell treatments reflects the perception that stem cells can cure anything. Indications range from the common – stroke, autism, multiple sclerosis, to Parkinson’s disease – to genetic diseases, injuries, degenerative conditions, and even infections. Yet some people seek stem cell support for “a fresh lease on life” or “rejuvenation.” More common, though, are tragic narratives of a “last option” or “a few months left.” They’re hard to read.

Making Sense of Crowdfunding for Unapproved Stem Cell Treatments
May 19, 2018
When FDA approval for a technology or treatment lags behind demand, crowdfunding steps in. Desperate patients or their families launch such campaigns when insurance won't help. And that goes for potential uses of stem cells.

Human Muscles From Stem Cells: Advance Could Aid Research Into Muscular Dystrophy, Other Diseases
January 26, 2018
For the first time, biomedical engineers have grown functioning skeletal muscle from human pluripotent stem cells.
Using stem cells enabled researchers from Duke University to improve upon similar efforts in 2015 that had started with more specialized cells called myoblasts, taken from muscle biopsies. Using true stem cells instead, fashioned from a person’s skin fibroblasts, avoids the painful biopsy and would theoretically up the output of mature muscle cells. The paper appears in the January 9 Nature Communications. Read More

Blinded By Stem Cells
March 19, 2017
The small wavy shimmers and fuzzy areas in the 78-year-old’s eyes had grown slowly, leading to a diagnosis of age-related macular degeneration (AMD), which affects more than 10 million Americans. She had the more common “dry” form. Despite 2 years of injections of one of the latest drugs (a vascular endothelial growth factor [VEGF] blocker), her sight was worsening. How much longer would she be able to drive, with a growing blob obscuring the center of her visual world?
Her family went online to research alternative approaches. Read More

Retinal Stem Cells and Eye of Newt
January 16, 2013
More than a decade before Sally Temple, PhD, and her husband Jeffrey Stern, MD, PhD, discovered stem cells in human eyes, they suspected the cells would be there. They knew it from the salamanders.
A SPECIAL FONDNESS FOR AMPHIBIANS
When William Shakespeare included “eye of newt” ingredients of the Three Witches’ brew in Macbeth, he probably knew what he was doing. Dr. Temple, who grew up in northern England, said it’s long been common knowledge there that newts can regrow their parts. In the late 1800s, biologists began to study regeneration in salamanders.
By the 1950s, embryologists had discovered that certain amphibian eyes regenerate thanks to a single layer of cells, called the retinal pigment epithelium (RPE), which hugs the photoreceptors (the rods and cones). Read More

DNA Science -- My New Blog at Public Library of Science (PLoS)
September 27, 2012
I have a new blog at Public Library of Science (PLoS), DNA Science. Each Thursday I'll explore stories from real people experiencing opportunities and challenges posed by biotechnology, including genetic testing, gene therapy, exome sequencing, stem cells, and more.
I like to find the stories that no one else tackles, connect topics in unusual ways, dip into bioethics, and wherever possible, bring in the historical perspective that shows that "overnight breakthroughs" are almost always anything but. And the PLoS tag is opening doors -- I spoke with Dr. Francis Collins yesterday!
The first blog is "Human Embryonic Stem Cells Finally Reach Clinical Trials: Maurie's Story."

Respiratory Replacement Parts -- Thanks to Stem Cells
November 29, 2011
We humans might not be able to regrow a leg, as can a cockroach or salamander, or regenerate a missing half, like a flatworm, but our organs can replenish themselves – thanks to stem cells. Two new reports about opposite ends of the respiratory system may pave the way for replacement breathing parts.

Stem Cell Ups and Downs
February 12, 2011
We expect too much of stem cells. The February 3 issue of Nature reveals both a setback and a stupendous achievement in the field.
