Effect of matrix stiffness on osteoblast functionalization [PDF]

Cell Proliferation, 2017
AbstractObjectivesStiffness of bone tissue differs response to its physiological or pathological status, such as osteoporosis or osteosclerosis. Consequently, the function of cells residing in bone tissue including osteoblasts (OBs), osteoclasts and osteocytes will be affected.

Interplay among cell migration, shaping, and traction force on a matrix with cell-scale stiffness heterogeneity

Biophysics and Physicobiology, 2022
In living tissues where cells migrate, the spatial distribution of mechanical properties, especially matrix stiffness, is generally heterogeneous, with cell scales ranging from 10 to 1000 μm.
