该视频描述了生成体外 3D 器官型皮肤重建以研究黑色素瘤进展的详细方案。这种皮肤模型模拟了体内器官的结构和多细胞复杂性。
所有涉及人类参与者的程序均已按照机构、国家和国际人类福利指南执行,并已由当地机构审查委员会审查。
1. 从表皮中分离原代角质形成细胞
2. 从真皮中分离原代成纤维细胞
3. 器官型全皮肤重建的真皮隔室的产生
4. 器官型全皮肤重建的表皮隔室的产生
5. 器官型全皮肤重建的气液培养

图 1:3D 器官型皮肤的培养在培养基中和气液界面处重建。在第 0 天,原代角质形成细胞接种在真皮区室的顶部,该室由嵌入 I 型胶原基质中的原代成纤维细胞组成。3D 皮肤重建在用 EGM 浸没培养 7 天,从插入壁上分离,并开始收缩。在第 8 天,将插入片段转移到 6 孔中并在气液界面培养以允许表皮分层。
