1. 使用pmaxGFP質粒進行進行預實驗，優(yōu)化HUVEC細胞核轉條件；

2. 檢測核轉條件對HUVEC細胞的Tube formation是否有影響；

3. 轉染siRNA，確定對細胞活力影響最小的最佳濃度，確定檢測蛋白表達降低的最佳時間點；

4. 評價siRNA對HUVEC細胞Tube Formation的影響。

 

圖1. HUVEC細胞轉染GFP質粒，轉染效率約為82%，對細胞形態(tài)無明顯影響：

圖2. HUVEC細胞進行核轉后，對Tube formation無明顯影響：

圖3. Anti-VEGFR2 siRNA轉染后的細胞對VEGF無反應，證明siRNA發(fā)揮作用。
