Tissue Train ®培養(yǎng)系統(tǒng)應(yīng)用背景

體外培養(yǎng)在與真實組織在結(jié)構(gòu)上和功能上相似的人工組織需要以下幾個基本條件：

（1）細胞

（2）支架矩陣組織

（3）培養(yǎng)基和生長因子和（4）機械刺激。這些條件彼此相互影響，并且相互之間共同來促進形成能夠承受生物機械力的，且結(jié)構(gòu)比較穩(wěn)定的組織。而在人工組成形成的過程中，這些細胞按照發(fā)育途徑形成具有一定幾何形狀的細胞外基質(zhì)結(jié)構(gòu)。其中一些信號轉(zhuǎn)導(dǎo)途徑參與了細胞外基質(zhì)組合物的形成。這些途徑中，有些是由細胞基質(zhì)的機械變形調(diào)節(jié)，并通過膜結(jié)合蛋白，如整合素，粘著斑復(fù)合體，細胞粘附分子和離子通道傳遞到細胞內(nèi)。這些途徑中細胞還可以響應(yīng)配體，如細胞基質(zhì)形變所釋放的細胞因子，激素或生長因子等。

為了維持肌肉骨骼組織的完整性和強度，組織內(nèi)細胞需要保持一定水平的的內(nèi)在應(yīng)力。如果缺乏這種內(nèi)在的應(yīng)力，組織會缺少強度導(dǎo)致細胞結(jié)構(gòu)的破壞或者組織的斷裂。目前一般認為如果在固定四肢，臥床休息或在內(nèi)在應(yīng)力水平的降低的情況下，將導(dǎo)致骨中礦物質(zhì)流失，骨組織萎縮，骨骼弱化，以及合成代謝活性的降低和分解代謝活性的增加。
