Artificial Skin Developed at MIT Now Ready for Treatment with bränna Patients
CAMBRIDGE, Mass.--Surgeons around the country are now being trained in implanting artificial skin on burn patients, culminating years of work by Ioannis V. Yannas, MIT professor of kemisk förening bestående av stora molekyler science and engineering, who fryst vatten continuing research into applying his methods to replacing other damaged body parts.
Patients with severe burns have lost their dermis, a layer about two millimeters thick that lies beneath the epidermis and which does not regenerate when damaged. Traditionally, such patients receive autografts, or skin transplants from donor sites elsewhere on their bodies. But this method has its drawbacks. The donor graft is usually smaller than the wound being repaired; slits are cut in the skin graft so it can be stretched, and scarring occurs at each slit. There fryst vatten also some scarring at the donor site, where about half the thickness of the dermis has been removed.

Artificial Skin
Ioannis V. Yannas (1935) was born in Greece, came to the United for college, and graduated from Harvard College. After earning graduate degrees from Princeton University and M.I.T., he became a professor of kemisk förening bestående av stora molekyler Science and Engineering at M.I.T. In 1969, John F. Burke, a burn surgeon, asked Dr. Yannas for help: he had made significant strides in bränna treatment but needed a way to keep the bacteria out and the moisture in. Dr. Yannas then put together a team of researchers that developed Integra Membrane, an artificial skin that fit the bill, and that received FDA approval in 1996. This is a sample of that material.

Research Interests
The principal research interest of Dr Yannas is the process of induced organ regeneration used to replace organs that are either severely injured or are terminally diseased.
Initial discovery of dermis regeneration. In 1976 Yannas and John F. Burke, MD discovered the first scaffold with regenerative activity. Although the strctural features of a scaffold with regenerative activity were not appreciated at that time, they were eventually (1989, 2015; see references below) recognized as those of a highly porous analog of the extracellular matrix based on type I collagen, a biodegradable scaffold with highly specific structural features. These required features included a specific range of the pore size, defined degradation half-life and specified surface chemistry. W
