Lineage tracing of Lgr5+ HFSCs and their progeny in papilloma and SCC development. Lgr5-Pten-/--mTmG mice (n=8) and Lgr5-mTmG mice (n=7) received treatment of DMBA/TPA. Lgr5-Pten-/--mTmG mice developed HF and epidermal hyperplasia, which contained increased amount of mT-/mG+ cells derived from Lgr5+ HFSCs. With progression of the disease, mT-/mG+ cells were found in papillomata and in SCC in Lgr5-Pten-/--mTmG mice, but not in Lgr5-mTmG mice. SCC, squamous cell carcinoma. Scale bars, 100 μm.
