● 根據(jù)腫瘤的生長(zhǎng)速度,觀察時(shí)間為2-10周。當(dāng)使用VitroGel和AB-ECM兩種細(xì)胞外基質(zhì)時(shí),六種實(shí)體瘤衍生的細(xì)胞系均能形成實(shí)體瘤,腫瘤類型和形態(tài)相似。
● 所有六種細(xì)胞類型應(yīng)用兩種細(xì)胞外基質(zhì),達(dá)到預(yù)定腫瘤體積大小所需的時(shí)間相同。
● 在大多數(shù)情況下,使用VitroGel系統(tǒng)移植的腫瘤顯示出較小的標(biāo)準(zhǔn)偏差,意味著VitroGel系統(tǒng)得到的實(shí)驗(yàn)結(jié)果可重復(fù),批次間一致。
● 以上結(jié)果說(shuō)明水凝膠VitroGel系統(tǒng)可以作為AB-ECM的無(wú)異源替代品的效率,是一款具有前景的替代品。

結(jié)論
VitroGel系統(tǒng)不僅可以作為AB-ECM的替代品,還可以為科研人員控制系統(tǒng)組分提供便捷,控制這種水凝膠系統(tǒng)關(guān)鍵的生物物理或生物特性,比如機(jī)械強(qiáng)度、功能配體和微環(huán)境的可降解度等。因此,選擇VitroGel系統(tǒng)開展體內(nèi)研究也是一種創(chuàng)新的選擇。
