Potent trophic activity of spermidine supramolecular complexes in in vitro models

Figure 3 Evaluation of Ki-67 antigen expression in reconstituted human vaginal epithelium. Ki-67 immunoreactivity was evaluated in reconstituted human vaginal epithelium exposed for 24 h to saline (A) or to spermidine-hyaluronate 50 (B). A typical result out of three independent experiments is shown (× 20 magnification).
