Building a Human Heart Valve
The World Heath Organization estimates that some 600,000 people around the
world will need replacement heart valves within the next three years. British
scientists delivered those patients some hopeful news: A team of researchers led
by Dr. Magdi Yacoub of the Imperial College of London saw 10 years of work
come to fruition this spring, when they grew bone marrow stem cells into
functioning human heart-valve tissue. Yacoub hopes that the tissue can be grown
into the shape of a heart valve using a special collagen scaffolding. Yacoub’s
advancements build on the ongoing efforts of scientists around the world to grow
new heart valves and other body parts. If Yacoub’s tissue holds up in animal
trials, he estimates it could be used in human heart-valve transplant patients
within 3 to 5 years.
ScientistsCreate “CyborgFlesh”
What with all our wearable tech and even smart contact lenses, it looks like
the future is going to be cyborg, and scientists at Harvard made that future even
more secure in 2015.Bioengineers at the university have managed to create the
first tissue samples that are half man, half machine. Researchers created hybrid
neurons, heart cells, muscle, and blood vessels by taking a collagen scaffold,
wiring it up with nanowires and transistors, then encouraging the “natural” tissue
to grow around it. The result has been dubbed NanoES (short for nanoelectric
scaffold) Tissue. Although we have a long way to go, the applications for this
technology are astonishing. You would be able to integrate your body into your
personal tech, and even perhaps control it from your smartphone (or whatever
we’ll be using by that point). Need a boost? Just open the adrenalin app.
Feeling burned out? A bit of serotonin should do you good? You could even use
it to monitor the body for abnormalities and alert to or even treat any developing
problems.
