求翻译：TDCC是将具有三维结构不同材料的载体与各种不同种类的细胞在体外共同培养 ,使得细胞能够分化产生一定的三维组织特异性结构 ,构成三维细胞载体复合物,如现在常用的基质胶 (matrigel),是一种从小鼠肿瘤组织中提取的物质。在室温下，它形成类似于体内的细胞外基底膜的胶状结构，把内皮细胞培Matrigel胶内，内皮细胞表现出新生血管的特征。Matrigel胶方法的局限性是并不能很好模仿体内肿瘤和血管内皮的微环境，细胞分离及提取困难，而且细胞因子的弥散受到一定的影响。是什么意思？

TDCC is a three-dimensional structure of the carrier with a variety of different materials, different types of cells co-cultured in vitro, making the cells can differentiate into a certain three-dimensional tissue-specific structure, form complex three-dimensional cell carrier, such as the now commo

TDCC will have a three-dimensional structure is different from the carrier materials with different types of cells in the body, causing cells to divide, to develop a three-dimensional Organization of the heterosexual structure, constitute a three-dimensional cell carrier compound, such as it is now

TDCC is to have a three dimensional structure of different material carriers together with the various different types of cells in vitro culture, allowing cells to have some three dimensional differentiation of tissue-specific structure, constitute a three-dimensional cell complex of carrier, such a

TDCC is trained outside the body together of the carriers that will have different materials of three-dimensional structure and the cells of different types, enable cell to differentiate and produce certain three-dimension and organize the specific structure, form carrier complex of three-dimensiona
