23 Jul Tissue engineered breast transplant and constructing method thereof
Abstract
The invention belongs to the technical field of construction of artificial organs by a tissue engineering method in biomedical engineering and relates to a tissue engineered breast transplant and a constructing method thereof. The tissue engineered breast transplant of the invention takes injectable material I type collagen gel as a carrier bracket and takes adipose-derived stem cells as seed cells; the seed cells are attached to the carrier bracket to form an adipose-derived stem cell/I type collagen gel compound; the final concentration of collagen is 2 mg/ml; and the cell density is 2*10<7>/ml. The tissue engineered breast transplant of the invention consists of injectable material-loaded autologous adipose-derived stem cells and is simple and convenient to prepare. Experiments prove that a new adipose tissue can be produced and the tissue engineered breast transplant is finally converted into autologous fat without an immunological rejection problem, so a new solution is provided for the filling and reconstruction of a breast.
