　　第一部分經(jīng)BMP9誘導(dǎo)后C3H10T1/2細(xì)胞JNK和ERK5的激活情況目的：檢測(cè)經(jīng)高滴度攜帶GFP和BMP9基因的重組腺病毒轉(zhuǎn)染C3H10T1/2細(xì)胞后JNK和ERK5的激活情況。方法：培養(yǎng)HEK293細(xì)胞，并用其對(duì)AdBMP9和AdGFP進(jìn)行擴(kuò)增，提高AdBMP9和AdGFP的滴度。高滴度AdBMP9和AdGFP轉(zhuǎn)染C3H10T1/2細(xì)胞24h后，熒光顯微鏡觀察GFP的表達(dá)情況并用流式細(xì)胞儀檢測(cè)轉(zhuǎn)染效率，免疫熒光技術(shù)定位p-JNK和p-ERK5在細(xì)胞內(nèi)的表達(dá)部位，利用CCK-8檢測(cè)特異性抑制劑對(duì)細(xì)胞生長(zhǎng)情況的影響，Western blot檢測(cè)加入JNK或ERK5信號(hào)通路特異性抑制劑SP600125或BIX02189并轉(zhuǎn)染后JNK和ERK5的激活情況。結(jié)果：1.流式細(xì)胞儀檢測(cè)高滴度AdBMP9和AdGFP轉(zhuǎn)染C3H10T1/2細(xì)胞24h后的轉(zhuǎn)染效率均可達(dá)50%左右。2.倒置顯微鏡下觀察AdBMP9轉(zhuǎn)染后細(xì)胞的形態(tài)隨培養(yǎng)時(shí)間的延長(zhǎng)由多邊形逐漸向長(zhǎng)梭形轉(zhuǎn)變，且細(xì)胞間鏈接更加緊密。3.免疫熒光技術(shù)結(jié)果顯示各組細(xì)胞的胞質(zhì)、胞核均可見p-JNK及p-ERK5的表達(dá)，但經(jīng)AdBMP9誘導(dǎo)后p-J...
