Cell size is weakly correlated to cell stiffness and cell transverse displacement.

Pearson coefficients are used to measure the strength of correlation. Except for K562 CD, which showed medium level of correlations, the other data showed weak correlations. The transverse displacement, cell diameter, and Young's modulus are represented as mean ± standard deviation. Sample size for K562 transverse displacement versus cell diameter is for each cell population. Sample size for K562 Young's modulus versus cell diameter is for each cell population. Sample size for HeyA8 and Jurkat Young's modulus versus cell diameter is and respectively.
