Profiling the Neoplasm Microenvironment of Silica Nanomaterial-Derived Scaffolds of Single, 2-, and 3-Composite Systems.

The challenges with scaffold profiling of cell-based assay includes accelerated cancer cell proliferation, induced scaffold toxicity, and identifying irrelevant cancer cell-based assays in batch assessments. This study investigates profiling carcinoma of breast cancer cells of MCF-7 model systems using silica nanoparticles scaffold sourced from synthetic materials and plant extracts. Herein, the engineered tissue scaffolds were used to create temporary structures for cancer cell attachments, differentiation, and subsequently to assess the metabolic activity of the cancer cell colonies. The cell viability of the cancer cells was assessed using the tetrazolium compound (MTS reagent), which was reduced to colored formazan, to indicate metabolically active cancer cells in a proliferating assay. We aimed to develop cancer cell-based scaffolds that not only mimic the neoplastic activity, but that also allowed synergistic interaction with cisplatin for in vitro assay screening.
