Description
本研究旨在探討牙髓幹細胞外泌體 (DPSC-exo) 對於預防治療放化療引起的口腔黏膜炎和口乾症的潛力與分子機制。實驗已初步證實DPSC-exo富含 microRNA let-7f,能有效減輕放射誘導的人類正常口腔角質細胞氧化損傷、細胞焦亡及促發炎因子釋放。從機制上來說,let-7f 可能藉由靶向 NLRP3 3'UTR,而抑制其表達,進而阻止細胞焦亡。本計畫將透過建立國人牙髓幹細胞與其外泌體庫、受試者口腔黏膜細胞與唾腺類器官培養系統以及放化療誘導的口腔黏膜炎併發口乾症臨床前動物模型,以全面評估DPSC-exo治療潛力。研究成果將闡明DPSC-exo用於口腔黏膜修復與唾腺再生的關鍵作用,提供開發基於齒源幹細胞外泌體的臨床治療策略,提升頭頸癌患者術後生活品質,亦有助於促進無細胞再生醫療產品研發與應用。
