目的　檢測腫瘤細胞上清液對成纖維細胞的激活情況及激活后血管內皮生長因子-A（VEGF-A）表達的變化規律。
方法　MTT法檢測普通培養液、含轉化生長因子-β1（TGF-β1）的普通培養液以及腫瘤細胞上清液組成的條件培養液對成纖維細胞生長情況的影響，用RT-PCR、Western blot及免疫組織化學法檢測不同培養條件下成纖維細胞的α-平滑肌肌動蛋白（α-SMA）與VEGF-A的表達。
結果　腫瘤細胞上清液對成纖維細胞的生長有一定的促進作用。含TGF-β1的普通培養液比普通培養液更有利于成纖維細胞轉化為肌成纖維細胞，并且能維持肌成纖維細胞的表型，但是二者均不表達VEGF-A；條件培養液能促進成纖維細胞穩定表達α-SMA和VEGF-A，二者在培養后第1天均開始表達，第3天表達量達到峰值，第3天以后表達穩定。
結論　腫瘤細胞上清液能夠有效、穩定地激活成纖維細胞為肌成纖維細胞，成纖維細胞的激活程度影響VEGF-A的表達，二者均具有最佳的激活時間點，并且最佳時間點相一致，最佳激活點的成纖維細胞有望成為一種可用于移植的促進血管重建的細胞。
