^aFrom seeded agarose construct (Kelly et al., 2004).

^bDetermined by the present method.

^cAverage cell strain relative to far-field tissue strain from FEA.

^dDifference in relative cell strains using the PCM modulus determined with the present method and a cell modulus of 3.4 kPa (Knight et al., 2002) versus cell (Guilak et al., 1999; Jones et al., 1999) and PCM (Guilak et al., 1999) properties determined using micro-aspiration.
