Skin-like tissue developed from human embryonic ...(racterization of these cell populations ...)

Date:7/21/2009

racterization of these cell populations, the researchers incorporated them into an engineered, three-dimensional tissue system where they were grown at an air-liquid interface to mimic their growth environment in the oral cavity. Within two weeks, tissues developed that were similar in structure to those constructed using mature cells derived from newborn skin, which are the current gold standard for tissue fabrication.

"These engineered tissues are remarkably similar to their human counterparts and can be used to address major concerns facing the field of stem cell biology that are related to their clinical use. We can now use these engineered tissues as 'tissue surrogates' to begin to predict how stable and safe hESC-derived cells will be after therapeutic transplantation. Our goal is to produce functional tissues to treat oral and skin conditions, like the early stages of cancer and inflammatory disease, as well as to accelerate the healing of recalcitrant wounds," said Garlick.
