目的:研究轉(zhuǎn)化生長(zhǎng)因子β1(TGF-β1)促進(jìn)Tenon囊成纖維細(xì)胞的增殖作用及核心蛋白多糖(decorin)對(duì)TGF-β1促Tenon囊成纖維細(xì)胞增殖的影響。方法:(1)取青光眼患者的Tenon囊組織,采用組織塊貼壁培養(yǎng)法進(jìn)行原代培養(yǎng)細(xì)胞培養(yǎng),細(xì)胞經(jīng)過(guò)冷凍與復(fù)蘇后,觀察細(xì)胞形態(tài)結(jié)構(gòu)與生物學(xué)特性。(2)用不同濃度(0.01、0.1、1、5、10ng/mL)TGF-β1作用于Tenon囊成纖維細(xì)胞48 h。(3)終濃度為5 ng/mL的TGF-β1 和不同濃度(0.01、0.1、1、2、5μg/mL)的decorin共同作用于Tenon囊成纖維細(xì)胞48h。MTT比色法檢測(cè)Tenon囊成纖維細(xì)胞增殖。結(jié)果:(1)體外成功培養(yǎng)Tenon囊成纖維細(xì)胞,細(xì)胞生長(zhǎng)活躍,形狀穩(wěn)定,細(xì)胞經(jīng)過(guò)冷凍與復(fù)蘇后,仍能保持其原來(lái)的細(xì)胞形態(tài)結(jié)構(gòu)與穩(wěn)定的生物學(xué)特性。(2)1~10ng/mL TGF-β1能促進(jìn)Tenon囊成纖維細(xì)胞的增殖,并與濃度成正比。(3)2~5μg/mL decorin 能抑制TGF-β1促Tenon囊成纖維細(xì)胞增殖作用,其抑制作用與濃度成正比。結(jié)論: TGF-β1可刺激Tenon囊成纖維細(xì)胞增殖,Decorin能抑制TGF-β1促進(jìn)細(xì)胞增殖的作用,其機(jī)理可能通過(guò)與TGF-β1結(jié)合抑制青光眼濾過(guò)手術(shù)后瘢痕形成。
