摘要

A method for cryopreservation of adherent cells attached to a substrate and a method for identifying one or more extracellular matrix (ECM) components and/or matricellular proteins that improves viability and retention of the cryopreserved cells on the substrate. The method for cryopreservation includes treating a substrate with at least one ECM component and/or adding at least one matricellular protein to the substrate or cell culture media, plating the cells on the treated substrate, and cryopreserving the cells. One or more ECM components and/or matricellular proteins that improves cell viability and retention can be identified by evaluating the cells that have been thawed from the cryopreservation temperature to determine cell viability and retention.
