2、轉(zhuǎn)移瘤形成的每一個步驟。BethanPsaila與DavidLyden針對這一土壤變化過程提出轉(zhuǎn)移前微環(huán)境(pre-metastaticniche)及轉(zhuǎn)移微環(huán)境(metastaticniche)假說,指出土壤的變化是轉(zhuǎn)移瘤形成的保障。該假說提出后迅速引起腫瘤研究界轟動。研究這一系列細胞分子生物學(xué)的改變,有助于闡明腫瘤轉(zhuǎn)移這一復(fù)雜的過程,為轉(zhuǎn)移干預(yù)帶來新的思路。關(guān)鍵詞:肺轉(zhuǎn)移瘤;轉(zhuǎn)移前微環(huán)境;轉(zhuǎn)移微環(huán)境中圖分類號:R734.2文獻標識碼:A文章編號:1007-4848(2011)06-0555-06Pre-metastaticNichea
