How cell structure can lead to health issues

Human bodies make 2 million red blood cells per second. They each live for 120 days and spend that time zooming completely around the body every 20 seconds, carrying oxygen from the lungs to other tissues and bringing back ...

Embedding aligned nanofibrous architectures within 3D-printed polycaprolactone scaffolds for tissue regeneration

The existing 3D-printed scaffolds commonly possess a thick feature size of hundreds of micrometers, which is too large for most cells (10–20 μm) to attach and proliferate for promoting tissue regeneration. Researchers ...

Nanotubes help healing hearts keep the beat

(Phys.org) —Carbon nanotubes serve as bridges that allow electrical signals to pass unhindered through new pediatric heart-defect patches invented at Rice University and Texas Children's Hospital.

Toward fixing damaged hearts through tissue engineering

In the U.S., someone suffers a heart attack every 34 seconds—their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients ...

'Bionic' cardiac patch could one day monitor and respond to cardiac problems

Scientists and doctors in recent decades have made vast leaps in the treatment of cardiac problems - particularly with the development in recent years of so-called "cardiac patches," swaths of engineered heart tissue that ...

Developing electrically active materials to repair damaged hearts

When a heart attack occurs, muscle in the heart tissue can be scarred, interfering with electrical activity necessary for healthy heart function. Drug treatments are available that alleviate further damage, but these don't ...

Using unconventional materials, like ice and eggshells, as scaffolds to grow tissues

As the global demand for tissue and organ transplants significantly outstrips supply, tissue engineering might provide a potential solution. But one of the significant challenges in tissue engineering is growing tissue in ...

Engineers craft the basic building block for electrospun nanofibers

Electrospinning uses electric fields to manipulate nanoscale and microscale fibers. The technique is well-developed but time-intensive and costly. A team from Michigan Technological University came up with a new way to create ...

Decoding a key part of the cell, atom by atom

Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. ...

Engineering heart valves for the many

The human heart beats approximately 35 million times every year, effectively pumping blood into the circulation via four different heart valves. Unfortunately, in over four million people each year, these delicate tissues ...
