TLDR
Xenogeneic decellularized scaffold was prepared with pig peritoneum by a series of biochemical treatments to retain normal three-dimensional tissue scaffold and remove cells and antigenic components from the tissue and can be further tested for skin tissue engineering.Abstract:
Skin damage is one of the common clinical skin diseases, and the main cure is the use of skin graft, especially for large area of skin injury or deep-skin damage. However, skin graft demand is far greater than that currently available. In this study, xenogeneic decellularized scaffold was prepared with pig peritoneum by a series of biochemical treatments to retain normal three-dimensional tissue scaffold and remove cells and antigenic components from the tissue. Scaffold was combined with hyaluronic acid (HA) plus two different concentrations of basic fibroblast growth factor (bFGF) and tested for its use for the repair of skin wounds. HA enhanced bFGF to adsorb to the decellularized scaffolds and slowed the release of bFGF from the scaffolds in vitro. A total of 20 rabbits were sacrificed on day 3, 6, 11, or 14 postsurgery. The wound healing rate and the thickness of dermis layer of each wound were determined for analyzing the wound repair. Statistical analysis was performed by the two-tailed Student's t...read more

TL;DR: Significant phenotypic and genotypic differences are demonstrated between primary human tumor-derived TSCs and their matched glioma cell lines, suggesting that TSC's may be a more reliable model than many commonly utilized cancer cell lines for understanding the biology of primary human tumors.

TL;DR: Although the desirable final result of coordinated healing would be the formation of tissue with a similar structure and comparable functions as with intact skin, regeneration is uncommon and results in a structurally and functionally satisfactory but not identical outcome.
