骨髓間充質(zhì)干細(xì)胞條件培養(yǎng)基通過抑制Notch1信號(hào)通路促進(jìn)神經(jīng)干細(xì)胞的有效分化
發(fā)布時(shí)間:2021-09-22 22:15
背景:脊髓損傷(SCI)可導(dǎo)致嚴(yán)重的運(yùn)動(dòng)、感覺障礙,對(duì)患者的生活產(chǎn)生巨大影響。近些年,針對(duì)創(chuàng)傷的不同階段,細(xì)胞治療的方法都對(duì)脊髓損傷后的組織的再生具有很大的潛力。神經(jīng)干細(xì)胞(NSCs)是一種具有固有分化能力的多能干細(xì)胞,尤其與促進(jìn)和重建受損的神經(jīng)元脊髓束有關(guān),神經(jīng)干細(xì)胞通過提供神經(jīng)營養(yǎng)支持和恢復(fù)突觸連接,在脊髓損傷移植后具有再生作用。損傷脊髓的微環(huán)境不利于移植細(xì)胞的生長和分化,受病理損傷產(chǎn)生的一系列抑制因子的限制。外源性神經(jīng)干細(xì)胞移植治療不能達(dá)到最佳效果,部分原因是神經(jīng)元分化和神經(jīng)元網(wǎng)絡(luò)重建有限。之前的研究發(fā)現(xiàn)當(dāng)NSCs與BMSCs共培養(yǎng)時(shí),神經(jīng)球細(xì)胞產(chǎn)生更多的神經(jīng)元和少突膠質(zhì)細(xì)胞。星形膠質(zhì)細(xì)胞增生是膠質(zhì)瘢痕形成的關(guān)鍵因素,Notch信號(hào)通路協(xié)調(diào)大量的細(xì)胞運(yùn)作,包括細(xì)胞增殖、代謝和分化,調(diào)控細(xì)胞在發(fā)育和成年期的生存,同時(shí)對(duì)神經(jīng)系統(tǒng)發(fā)育的有重要的影響和作用,包括神經(jīng)元分化和神經(jīng)膠質(zhì)的決定。目的:本研究旨在討論在骨髓間充質(zhì)干細(xì)胞條件培養(yǎng)基(BMSC-CM)對(duì)神經(jīng)干細(xì)胞(NSCs)分化的影響及該過程中Notch1信號(hào)通路在其中的作用。方法:對(duì)NSCs及BMSCs進(jìn)行體外培養(yǎng),在不同分化培養(yǎng)液...
