Figure S1. Treatment with LPS and clodronate does not result in significant cell death. (a–d) OHSCs were live-stained with propidium iodide 7 days after LPS treatment (at 21 days in vitro). There was no significant cell death in control (a), LPS (b), clodronate treated (c) or LPS + clodronate (d) treated OHSCs. As a positive control, OHSCs treated with 100% ethanol for 5 min showed extensive propidium iodide labelling indicating mass cell death (e). (JPG 244 kb)
