Standard Guide for Quantitating Cell Viability Within Biomaterial Scaffolds
|Publication Date:||1 August 2008|
This guide is a resource of cell viability test methods that can be used to assess the number and distribution of viable and non-viable cells within porous and non-porous, hard or soft biomaterial scaffolds, such as those used in tissue engineered medical products (TEMPs).
In addition to providing a compendium of available techniques, this guide describes materials specific interactions with the cell assays that can interfere with accurate cell viability analysis, and includes guidance on how to avoid, and/or account for, scaffold material/cell viability assay interactions.
These methods can be used for 3-D scaffolds containing cells that have been cultured in vitro or for scaffold/cell constructs that are retrieved after implantation in living organisms.
This guide does not propose acceptance criteria based on the application of cell viability test methods.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This 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 and health practices and determine the applicability of regulatory limitations prior to use.
