23 Jul Heterogeneous cell-free hypodermal framework and its prepn
Abstract
The present invention relates to the skin tissue engineering technology in medicine and is heterogeneous cell-free hypodermal cradle and its preparation. It is essential to close wound fast and effectively in treating serious burns, trauma and ulcer. In the present invention, sucking pig skin is used in making hypodermal cradle, and cell-free hypodermal cradle is modified in spatial structure andsurface physical and chemical characteristics. That is, the cell-free hypodermal cradle is treated with trypsin to increase collagenous fibre interval to favor cell amplification in wound and speed vascularization and is soaked in glutaric dialdehyde solution to alter the surface physical and chemical characteristics of hypodermal cradle and to reduce immunologic rejection and occupancy.
