OBJECTIVE: To further understand the mechanic properties of the Intestinal Epithelial cells (IEC).
METHODS: The viscoelastic properties of the IEC-6 were determined by micropipette aspiration.
RESULTS: The elastic coefficient K1 was 436.21 +/- 89.64 dyn/cm2 and K2 was 298.37 +/- 75.16 dyn/cm2. The visous coefficient micro was 15.94 +/- 4.93 dyn/(sec x cm2).
CONCLUSION: The elastic component reflects the degree of initial deformation of the IEC and makes a notable impact on the deformation of the IEC. The viscous component reflects the time dependency of the deformation of the IEC and influences the velocity of the IEC deformation.
