Skin From Hair

skin grafting%20%28300%20x%20225%29 Skin From HairGerman researchers have developed a method to artificially grow skin cells in a lab that are derived from a patient’s own stem cells found within hair roots. This work has a potential for all kinds of clinical and biomedical applications, such as plastic and reconstructive surgery, and development of specialized implants.

“We pluck a few hairs off the back of the patient’s head and extract adult stem cells from their roots, which we then proliferate in a cell culture for about two weeks. Then we reduce the nutrient solution until it no longer covers the upper sides of the cells, exposing them to the surrounding air. The increased pressure exerted by the oxygen on the surfaces of the cells causes them to differentiate into skin cells,” explains Emmendörffer. In this way, the researchers can grow numerous small pieces of skin, produced individually for each patient, which add up to a surface area of 10 to 100 square centimeters when pieced together. To ensure that they comply with the safety regulations at all times, the researchers are using new cleanrooms at the IZI, a state-of-the-art facility for producing different kinds of cell therapeutics. “We continuously measure the number of particles in the cleanrooms. If there are too many particles in the air, an alarm goes off,” says Schmiedeknecht. The researchers expect to grow skin grafts for 10 to 20 patients a month in 2008, depending on how many doctors prescribe this therapy.

Low-frequency Ultrasound for Chronic Wounds

Low-frequency Ultrasound for Chronic Wounds

Researchers at the Fraunhofer Institute for Machine Tools and Forming Technology IWU in Dresden (Fraunhofer-Institut für Werkzeugmaschinen und Umformtechnik IWU) developed a variable frequency ultrasound system that might have potential in the treatment of chronic wounds:

Unlike the ultrasound used in prenatal examinations, which operates at frequencies of several hundred kilohertz, the frequencies used here are measured in tens of kilohertz. Devices operating at fixed frequencies are already available. But what effect does the treatment have on the patient’s circulation? The only empirical data that exists at present is based on patient surveys.

FusionOptic™ Technology from Leica

FusionOptic™ Technology from Leica

We’ve seen quite a few devices that are designed to improve all sorts of neurologic functions. However, we’ve never seen a medical gadget that is designed to utilize normal human neurology for improvement of its own function. And that is what FusionOptic™ Technology from Leica is supposedly doing: increasing the resolution of stereomicroscopes, models M205 C and M165 C, by delivering two different images to each eye.
From the press release about Leica M205 C, a model just introduced at the Medica 2007 in Düsseldorf (shown above; M165 C model is shown below).

FulFil Adjustable Face Implant Goes Strong for Two Years

FulFil Adjustable Face Implant Goes Strong for Two Years

Evera Medical, a Foster City, CA manufacturer of the facial saline-adjustable implant FulFil, is reporting that more than 670 of the devices have been implanted in the last two years with “no serious adverse events.” The company markets its implants under two names, with FulFil™ being an international product, which was issued the European CE Mark in April for “augmentation of facial soft tissue, including lip augmentation,” and in the US the device is called VeraFil™, and it was cleared by the FDA for “augmentation and reconstruction in and around the orbit of the eye,” according to Evera Medical.
We have not seen this device before, so here’s a quick look at the company’s technology:

Breast Implants Linked to Suicide

Research is showing that women who have had breast implant surgery are more likely to attempt suicide later in life From the Washington Times:

“Dr. Lipworth [an epidemiologist at Vanderbilt University Medical Center] analyzed the medical histories and death certificate data on 3,527 women who had cosmetic breast implant surgery between 1965 and 1993, following them for almost two decades after their surgeries. She found the suicide rate was triple that of women without implants. The risk was greatest – seven times higher – for women who got implants after turning 45.”

Breastgadget: Pointing the Way to Natural Breasts

Breastgadget: Pointing the Way to Natural Breasts

There’s no doubt that breast implants serve a legitimate purpose, such as in cases of reconstruction. And yet, we’ve noticed the attention paid to breast augmentation technology far outstrips this limited role. You might say the desire for larger breasts in general has been occupying an ample portion of our male and female population’s interest for the past century or so.

Sifting through all these huge tracts of research may feel overwhelming — but don’t let your spirits sag. Our Breastgadget column keeps you up to date on important events in the breast industry.

Laboratory-manufactured Human Skin Shows Promise in Trial

Laboratory-manufactured Human Skin Shows Promise in Trial

Intercytex Group plc, a Cambridge, UK company, is reporting positive results from a recently completed Phase I trial of its allogeneic skin graft replacement, called ICX-SKN. For the common peasant, allogeneic means from an unrelated donor.

In the trial (which is published today in the July issue of Regenerative Medicine, available now for online viewing at www.futuremedicine.com), a full-thickness skin sample was excised from the upper arm of six volunteers and replaced with Intercytex’ skin graft replacement product, ICX-SKN. After 28 days both visual and histological analysis showed that in all volunteers the ICX-SKN grafts were rapidly vascularised and overgrown with the hosts’ own cells, resulting in a fully integrated skin graft that had closed and healed the wound site.

Save The Implants!! Detecting Silicone Breast Implant Leakage

Canadian researchers are afraid the FDA’s stringent rules about MRI screening of silicone implants will negatively affect breast size. That is why they have devoted themselves to finding a cheap, easy blood test to detect leaky implants.
