Cryopreservation of engineered tissue equivalents (TE) has achieved limited success. Successful preservation of a functional TE or tissue could provide prolonged transplantation time windows or off-the-shelf availability of engineered tissues. A quantitative understanding of the freezing-induced cell-fluid-matrix mechanical interaction is critical towards successful preservation of functional tissue. Using quantum dot-mediated cell image deformetry, Teo et al have experimentally mapped the instantaneous deformation of a TE during freezing process and showed its resulting volume change after thawing due to fluid loss . To further our understanding of the freezing-induced fluid-matrix interaction, we have developed a biphasic model that simulates the transient of thermal load, its resulting TE elastic deformation, the corresponding pressure redistribution within, and the fluid movement in the TE.
