Standard Practice for Use of a Centrifugation Method to Quantify/Study Cell-Material Adhesive Interactions
1.1This practice covers a centrifugation cell adhesion assay that can be used to detect changes in adhesive characteristics of cells with passage or treatments. This approach measures the force required to detach cells from a substrate. Adhesion, among many variables, may vary due to changes in the phenotype of the cells.
1.2This practice does not cover methods to verify the uniformity of coating of surfaces, nor does it cover methods for characterizing surfaces.
1.3The cells may include adult, progenitor, or stem cells from any species. The types of cells may include chondrocytes, fibroblasts, osteoblast, islet cells, or other relevant adherent cell types.
1.4This practice does not cover methods for isolating or harvesting of cells. This practice does not cover methods to quantitate changes in gene expression, or changes in biomarker type or concentration, as identified by immunostaining. Nor does this practice cover quantitative image analysis techniques.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
