Abstract:
BACKGROUND:The use of three-dimensional cel culture techniques can better simulate the cel ular microenvironment, providing new tools for tissue engineering research.
OBJECTIVE:To analyze the biomaterial selection and application characteristics in three-dimensional cel culture as wel as applications in tumor tissue engineering.
METHODS:We searched Wanfang database and PubMed database 1998-2015 years for relevant literature using keywords of“three-dimensional cultures;scaffold;cel growth;cel differentiation;tumor tissue engineering”in Chinese and English, respectively.
RESULTS AND CONCLUSION:The selection and application of three-dimensional scaffold materials is one of the keys. So far, scaffold materials, such as col agen gels, gelatin sponge, agarose, chitosan, demineralized bone matrix, cannot provide the extracel ular matrix similar to the micro-environment in which seed cel growth and proliferation are not affected, and the ability to secrete type II col agen and glycosaminoglycan is decreased, although they can provide three-dimensional space for seed cel s. Biomimetic scaffold characterized as little trauma and strong plasticity gradual y shows its unique advantages. Three-dimensional culture conditions raise pro-angiogenic growth factor secretion from tumor cel s, and this feature is positively correlated with the occurrence of in vivo tumor angiogenesis.
