It sounds like a concrete experiment. Concerning the part of proving the activation/stimulus of senescent cells reprogramming, we could use cell cycle analysis using flow cytometry to see if cells entered the cell cycle. This, followed by transcriptomic data could be a more convincing proof of activation.
