DeepFreeze 3D-biofabrication for Bioengineering and Storage of Stem Cells in Thick and Large-Scale Human Tissue Analogs.

The storage modulus shows an increasing trend with increased frequency, while the Tan (delta), a ratio of loss modulus and storage modulus, increases at a lower frequency and then shows a decreasing trend of frequency, indicating a gel‐like behavior (Figure S2A,B , Supporting Information).
