Viscoelastic descriptors over time measured in the bioreactor: (A) instantaneous, ${\mathrm{E}}_{\mathrm{inst}}={\mathrm{E}}_0$ and (B) equilibrium modulus, $({\mathrm{E}}_{\mathrm{eq}}=\frac{{\mathrm{E}}_0{\mathrm{E}}_1}{{\mathrm{E}}_0+{\mathrm{E}}_1})$, and (C) retardation time, $\mathsf{\tau }={\mathsf{\eta }}_1/{\mathrm{E}}_1$ (* = p < 0.05).
