Abstract:
Aims To design and fabricate the 3 D cell cultural microfluidic chip for tumor cell culturing, with which to research the compatible conditions for gelatin forming and dissolving with calcium alginate as the scaffolds. To culture SMMC-7721 cells in the chip and to detect the surviving rate. Methods The microfluid-ic chip was fabricated with the software Corel Draw, the technology of soft lithography, molding, and plas-ma bonding. The applicability was tested and cells were cultured on it, on which the cell status was ob-served, their surviving rate was calculated with the help of the software IPP. Results The chip we fabri-cate was calculated is suitable for cell 3D culturing, the tumor cells showed a favorable proliferation ability in 72 h on chip, the surviving rate was ( 96. 1 ± 4. 5)%. The cells were solid and TCS appeared. Con-clusion The microfluidic chip manufactured appeared for tumor cell 3D culture, is suitable for the growth of SMMC-7721 and the cells are indubitable. They show some different status in proliferative and agminated compared with traditional 2D cell culture. With the chip and the condition found, there will be a better way to study the characteristics of tumor cells and is beneficial to the screen of anti-tumor drugs.
