If you’ve lost your way on the Boston subway, you need only consult a map to find the best route to your destination. Now stem cell engineers have a similar map to guide the making of cells and tissues for disease modeling, drug testing and regenerative medicine. It’s a computer algorithm known as CellNet.
As in this map on the cover of Cell, a cell has many possible destinations or “fates,” and can arrive at them through three main stem cell engineering methods:
• reprogramming (dialing a specialized cell, such as a skin cell, back to a stem-like state with full tissue-making potential)
• differentiation (pushing a stem cell to become a particular cell type, such as a blood cell)
• direct conversion (changing one kind of specialized cell to another kind)
Freely available on the Internet, CellNet provides clues to which methods of cellular engineering are most effective—and acts as a much-needed quality control tool. Full story »
Fitbit, Jawbone, Nike, Withings…a lot of companies are already in the wearable/mobile health technology and data tracking game. But a couple of really big players are stepping on to the court.
At their most recent Worldwide Developers Conference, Apple announced both an app and a framework—Health and HealthKit—that will tie in with various wearable technologies and health apps. HealthKit will also feed data into electronic medical record (EMR) systems like Epic, which runs at some of the largest hospitals in the country. And rumors abound that an upcoming Apple smartwatch (iWatch? iTime? Only Tim Cook knows right now) will carry a host of sensors for tracking activity and health data.
Google also wants to get into the game with a health data framework called Fit that they announced at their I/O conference in June. Unlike Apple, its strategy seems more focused on providing a standard way for trackers, devices and apps from different manufacturers to talk to Android Wear devices.
What will entry of these big players mean? We asked Michael Docktor, MD, clinical director of Boston Children’s Hospital’s Innovation Acceleration Program. Full story »

A new proposal suggests spreading drug development risk among many small investors.
There’s no way around it. Obtaining approval to market a new drug is lengthy, complex, costly and fraught with uncertainty and risk. Financial engineers at MIT propose a strategy to minimize that risk—one that deserves a close look.
In the last 10 years, the aggregate cost of pharmaceutical research and development has doubled, but the number of approved products has remained the same. To compound the problem, a $1.6 billion reduction in NIH funding, caused by the 2013 sequester, has stalled research projects at more than 2,500 research institutions supported by grants. Pressure from investors and stakeholders is pushing pharmaceutical companies to focus on projects with a greater chance of financial success.
As a result, translational studies—those that bridge the gap between basic research and clinical trials—continue to be neglected and account for less than 12 percent of total research funding. Full story »
Projections that the global mobile health market will boom to nearly $50 billion have ignited interest among innovators. A pair of physician innovators from Boston Children’s Hospital peg wearables as the technology to watch and offer a sneak peek at what adoption might mean, while others ask about the pediatric market for wearables and point to a few potential stumbling blocks. Read on for their views. Full story »

If you Google the term “millennials,” you’ll see that Google automatically fills in such search terms as “millennials lazy,” “millennials spoiled,” “millennials trophy kids” and “millennials entitled.” Ouch.
As part of the Mayor’s ONEin3 Council and a Founding Hacker for MIT’s H@cking Medicine, I could not disagree more with this assessment of my generation. I’ve observed young people increasingly drawn to civically minded work with public impact—including work in health tech. Full story »
Emmie Mendes was lucky enough to be diagnosed before age 3, but many families face a much longer journey.
At first, Corrie and Adam Mendes thought their daughter Emmie had an inner ear problem. She was late with several early milestones, including walking, and when she did walk, she often lost her balance. The family pediatrician sent them to a neurologist, who ordered a brain MRI and diagnosed her with pachygyria, a rare condition in which the brain is smoother than normal, lacking its usual number of folds.
Additionally, Emmie’s ventricles, the fluid-filled cushions around the brain, looked enlarged, so the neurologist recommended brain surgery to install a shunt to drain off fluid. He advised Corrie and Adam that Emmie’s life expectancy would be greatly reduced.
As Corrie recounts on her blog, Emmie’s Story, she went online and came across the research laboratory of Christopher Walsh, MD, PhD, at Boston Children’s Hospital. The lab does research on brain malformations and has an affiliated Brain Development and Genetics Clinic that can provide medical care.
After Walsh’s team reviewed Emmie’s MRI scan, genetic counselor Brenda Barry invited the family up from Florida. Full story »
You’d think drugs meant to be taken by children for years would be studied in children for a long time to measure their long-term safety.
You’d think drugs for a condition affecting millions of children would be tested in many, many children to catch any rare side effects.
You’d think all this would happen before the Food and Drug Administration, an agency known for its strict criteria, approved them for marketing.
But if a new PLoS ONE paper by Boston Children’s Hospital’s Florence Bourgeois, MD, MPH, and Kenneth Mandl, MD, MPH, is any indication, you’d be wrong.
In it, the pair reports that the FDA approved 20 attention deficit hyperactivity disorder (ADHD) drugs over the last 60 years without what would be considered sufficient long-term safety and rare adverse event data.
Their findings, they say, point to larger issues in how the FDA’s approval process addresses the long-term safety of drugs intended for chronic use in children. Full story »
The start of what promises to be a lengthy, multi-part endeavor has begun unfolding on Capitol Hill. It’s an attempt to reform the Medicaid program so that children with medical complexity (those with a single, serious medical condition, or multiple chronic conditions) can receive higher quality care with fewer emergency department visits and fewer hospital admissions.
When you think of medically complex children, think of children living with conditions such as spina bifida or cerebral palsy, children dependent on ventilators or feeding tubes, or children with genetic disorders. They represent just 6 percent of the 43 million children on Medicaid—yet they account for about 40 percent of Medicaid’s spending on children. Their care is often fragmented and poorly coordinated.
The reform effort, led by more than 60 participating pediatric hospitals and supported by the Children’s Hospital Association (CHA), focuses on Medicaid because it’s the single largest insurance provider for children. The backdrop is a cost-conscious Congress that’s the most politically polarized ever, passing the fewest bills ever. Full story »
Alexander Rotenberg, MD, PhD, is a pediatric neurologist and epileptologist at Boston Children’s Hospital and director of the hospital’s Neuromodulation Program.
In recent years, electrical devices stimulating the brain or peripheral nerves have emerged as clinical and scientific tools in neurology and psychiatry. In 2014, the Food and Drug Administration has approved three tools at this writing: a device for treatment of epileptic seizures via electrodes implanted beneath the skull; a device for shortening migraine headache via transcranial magnetic stimulation (TMS) of the brain; and a transcutaneous electrical nerve stimulation (TENS) device for migraine prevention. (Click image below for details.)
Stimulating the nervous system to treat neuropsychiatric symptoms is not new. In the first century AD, the Roman physician Scribonius Largus documented treating headaches by applying electric torpedo fish to the head. Full story »
Perhaps counter-intuitively, rare diseases can present attractive business opportunities for pharmaceutical companies. As discussed previously on Vector, they generally offer:
1) a population of patients with a high, unmet need, greatly lowering the bar to FDA approval
2) a closely networked disease community, greatly lowering the bar to creating disease registries and mounting clinical trials
3) well-studied disease pathways.
Recoiling from expensive failures of would-be blockbuster drugs, companies like Pfizer, Novartis, GlaxoSmithKline, Sanofi, Shire and Roche are embracing rare diseases, despite their small market sizes, because of their much clearer path to clinic. But in the current risk-averse industry environment, some projects are stalling. Industry may need more incentive to jump in—and Cydan Development is basing its business model on providing it.
