Using a functional proliferation reporter we identified quiescent tumor propagating cancer cells (TPCs) in intact squamous cell carcinomas, and found that TGFβ signaling controls their reversible entry into a growth arrested state, which protects TPCs from chemotherapy. TPCs with compromised TGFβ/Smad signaling can't enter quiescence and subsequently die from chemotherapy.
利用一种功能性增殖报告基因,我们在完整的鳞状细胞癌中鉴定出静止的肿瘤增殖癌细胞(TPCs),并发现转化生长因子β(TGFβ)信号传导控制它们可逆地进入生长停滞状态,从而保护TPCs免受化疗影响。TGFβ/ Smad信号传导受损的TPCs无法进入静止状态,随后死于化疗。
