LOP05: Sustainable fat grafting – Optimizing fat grafting in an in vivo tissue engineering chamber model

499 the adipose tissue was confirmed histologically. CD-31-positive blood vessels could exclusively be found in the ASC-HUVEC group. The results of the quantitative histomorphometry showed corresponding to the MRI-results a superior average seize of the constructs of the ASC-EPC group after 24 weeks. Conclusions: Combining ASCs with EPCs appears as a promising approach to achieve long-term volume persistence in tissueengineered adipose grafts. Thus, the co-implantation of both cell types might be a therapeutic method for the correction of volume deformities in plastic and reconstructive surgery.
