Biomaterial Tricks Immune System to Grow New Blood Vessels
Researchers from Harvard’s Wyss Institute have developed a new biomaterial that can activate T cells to promote vascularization of ischemic tissues. Their work demonstrates that the biomaterial results in local blood vessel development, increased perfusion, and new muscle growth after ischemia.
Various compounds have been tested to try to improve angiogenesis in tissues that have undergone ischemia, but they have failed in various ways. New interest has developed in using the body’s own immune system to help aid this process. To this end, the Wyss researchers developed unique biomaterials to modulate the local i...

Magnetically Controlled Soft Robots to Operate on Human Body
Although a myriad of robots is already used in a variety of industries, including medicine, they’re almost exclusively rigid devices using conventional mechanics. To best work with the pliability of the human body, it may be advantageous for medical robots to be soft and not include gears, motors, and metal cables.
Researchers at North Carolina State University and nearby Elon University have now developed such robots and have recently reported a technique that allows others to build similar devices designed for unique applications.
The robots are made using a shape-memory polymer seeded with magnetic iron part...

Getting the Toe Out of a Jam
Toe jam injuries are extremely painful because the feet have sensitive parts and a delicate anatomy. Patients, especially women, care about cosmetic results. EPs should consider the emergency concerns of foot wound closure and cosmetic results when attempting repair. More importantly, patients with neuropathies, diabetes, and vascular diseases warrant close attention to detail to prevent complications. High-risk patients can develop serious infections, which could result in the loss of a toe or limb. It might be excessive to call a plastic surgeon to consult on a foot wound, but it may be appropriate to consult podiatry or...

Using Microparticles to Measure Oxygen in Tissues
The field of tissue engineering is rapidly progressing, in large part thanks to hydrogel scaffolds that provide a comfortable home for new cells. A major issue that researchers bump against is tracking how well oxygen reaches freshly grown cells within such scaffolds, which can indicate how well the new cells are generally functioning.
Now, researchers at Rice University have developed special microparticles, that are soft and non-toxic to living cells, that glow in relation to how oxygenated their environment is. These microparticles are particularly well suited to measuring oxygen within three-dimensional structures, ...

Notice: Allergan Withdraws Textured Breast Implants
Allergan has announced today that it has voluntarily withdrawn BIOCELL Textured Breast Implants and Tissue Expanders from the worldwide market.Effective immediately, healthcare providers will no longer implant new BIOCELL ® textured breast implants and tissue expanders and unused products should be returned to Allergan. The withdrawal followed a request of the US FDA, which was based on new available data.Allergen emphasized that there is still no recommendation to remove or replace textured breast implants from patients without symptoms.I have implanted only a handful of this type of implant over the past 20 years. ...

Smart Bandage Pulls Skin Together to Speed Healing
Wounds on the skin are usually treated with bandages that protect the area and keep it moist, but which don’t actively help to promote healing. Researchers at Harvard and McGill universities have now created a mechanotherapy bandage that actually works to close the wound, keeps it protected from microbes, and speeds up healing much faster that existing products. The researchers have dubbed their approach as “active adhesive dressings” (AADs), and they believe that soon these may be coming to a pharmacy near you.
The new bandages are possible thanks to heat-responsive hydrogels that are strong and, ...

Dermal fillers: The good, the bad and the dangerous
The four major structural components of our face are skin, fat, muscle, and bone. As we age, volume loss in these structures contributes to many of the visible signs of aging. Dermal fillers may help.
Over time, age-related bone loss in the face can lead to retraction of the jawline, descent of the nose, and loss of high cheekbones. The facial muscles also decrease in volume and elasticity, and deflation and movement of facial fat further accentuates the signs of aging. Finally, the skin stretches and loses elasticity — compounded by the loss of scaffolding provided by fat, muscle, and bone, this leads to wrinkles, saggi...

Printing Skin, Bones for Surgeries on Way to Mars
Traveling to Mars, our closest planet and which may one day serve as another base for humanity, is very far away. Any practical mission there and back will take years. The health of the astronauts undertaking such a journey will be paramount, so researchers are working on ways to be able to create customized tissues in space. This ability would give astronauts a way to restore damaged or diseased tissues, an ability that would also certainly be nice to have down here on Earth.
At the University Hospital of Dresden Technical University, researchers working with OHB Systems AG and Blue Horizon, two firms involved in topic...

Floating Flexible Sensor to Monitor Engineered Tissues and Cell Cultures
Tissue engineering is a vibrant research field poised to revolutionize how we heal organs and tissues following damage from injury and disease. One of the difficulties that scientists working with cultured cells discover is the inability to closely monitor a number of characteristics of their cellular cultures. One reason is that water and electronics don’t mix, so technologies that would be useful in monitoring cells can be hard to implement.
Now, engineers at Purdue University have developed a way to let electronic sensors make intimate contact with a cell culture while separating the functional electric compone...

Protein-Loaded Antimicrobial Hydrogel to Treat, Prevent Bone Infections
Bone infections are quite common following orthopedic surgery or as a result of injury or disease. They can be incredibly difficult to treat, and heavy duty antibiotic regimens coupled with debridement surgery is the current approach. Even after all that, inflammation is a frequent side effect. Now, researchers at Georgia Tech have created a hydrogel material that can be used to treat bone infections and even prevent them from happening following surgery.
Their hydrogel contains lysostaphin, an antimicrobial enzyme that kills bacteria but that doesn’t increase inflammation. Previously, lysostaphin was not very...

3D-Printing Utilized to Grow New Human Hair
Researchers from the Columbia University Irving Medical Center have developed a tissue engineering and 3D printing method to grow new hair follicles and stop hair loss. Their work, recently published in Nature Communications, demonstrates that they were able to grow human hair follicles in a dish and on mice for the first time. These hair follicles could be used to address hair thinning and pattern baldness that affects millions of Americans.
This innovation arises, in part, due to recent advances in 3D printing that enabled the researchers to create a unique patterning device. The printed device has long extensions th...
