FIG. 1.

In vitro transgene expression levels by adenovirally (Ad-SDF-BMP, Ad-SDF-RFP, and Ad-RFP-BMP) transduced fat tissue grafts were assessed in vitro up to 22 days using SDF-1α and BMP-2 ELISA (n=3 for each time point). Ad-SDF-BMP transduction resulted in temporal expression levels of both SDF-1α and BMP-2 comparable to transduction by the single-target gene vectors Ad-SDF-RFP and Ad-RFP-BMP. Bone morphogenetic protein 2 (BMP-2), stromal cell-derived factor 1 alpha (SDF-1α), red fluorescent protein (RFP), enzyme-linked immunosorbent assay (ELISA).
