3D細(xì)胞培養(yǎng)是一種在三維空間內(nèi)培養(yǎng)細(xì)胞的技術(shù)，與傳統(tǒng)的2D細(xì)胞培養(yǎng)不同。在3D細(xì)胞培養(yǎng)中，細(xì)胞可以自然地形成復(fù)雜的三維結(jié)構(gòu)，如球體、管狀結(jié)構(gòu)和多層結(jié)構(gòu)等，這種結(jié)構(gòu)更接近于生物體內(nèi)的真實(shí)環(huán)境。3D細(xì)胞培養(yǎng)技術(shù)已經(jīng)被廣泛應(yīng)用于癌癥研究、組織工程、藥物篩選等領(lǐng)域。它可以提供更準(zhǔn)確的生物學(xué)信息，例如細(xì)胞-細(xì)胞相互作用、細(xì)胞-基質(zhì)相互作用以及化學(xué)梯度的影響。此外，3D細(xì)胞培養(yǎng)還可以更好地模擬生物體內(nèi)的微環(huán)境，從而更好地預(yù)測藥物反應(yīng)和疾病發(fā)展。 ??
