Abstract
Assessment of cell cytotoxicity following transfection of cells with microRNA (miRNA) is an essential step in the evaluation of basic miRNA functional effects within cells in both 2D and 3D microenvironments. The lactate dehydrogenase (LDH) assay is a colorimetric assay that provides a basic, dependable method for determining cellular cytotoxicity through assessment of the level of plasma membrane damage in a cell population. Here, we describe the overexpression of miRNA in breast cancer cells when cultured in 3D collagen-based biomaterial scaffolds, achieved by Lipofectamine transfection, with subsequent examination of cell cytotoxicity using the LDH assay.
