abstract

Freezing is a common technique for preservation of isolated cells, and extending its applications to the preservation of tissues would have important implications for the storage and distribution of tissue engineered products. Unlike isolated cells in suspension, cells in tissue interact with each other, and this interaction is known to affect the outcome of tissue cryopreservation. As a consequence, our knowledge of the cryobiology of isolated cells cannot simply be extrapolated to tissues, and new models, which consider the interaction between cells, need to be developed. The model that we propose is based on previous quantitative analysis of intercellular ice propagation in a micropatterned two-cell system. We used Monte Carlo simulations to extrapolate the results from cell pairs to two-dimensional and three-dimensional tissues. Effects of tissue geometry, cellular connectivity, and degree of intercellular interaction were investigated.
