Functional and Biomimetic Materials for Engineering of the Three-Dimensional Cell Microenvironment

Chemical Reviews, Journal Year: 2017, Volume and Issue: 117(20), P. 12764 - 12850

The cell microenvironment has emerged as a key determinant of behavior and function in development, physiology, pathophysiology. extracellular matrix (ECM) within the serves not only structural foundation for cells but also source three-dimensional (3D) biochemical biophysical cues that trigger regulate behaviors. Increasing evidence suggests 3D character is required development many critical responses observed vivo, fueling surge functional biomimetic materials engineering microenvironment.

Collective cell durotaxis emerges from long-range intercellular force transmission

Science, Journal Year: 2016, Volume and Issue: 353(6304), P. 1157 - 1161

Published: Sept. 8, 2016

The ability of cells to follow gradients extracellular matrix stiffness-durotaxis-has been implicated in development, fibrosis, and cancer. Here, we found multicellular clusters that exhibited durotaxis even if isolated constituent did not. This emergent mode directed collective cell migration applied a variety epithelial types, required the action myosin motors, originated from supracellular transmission contractile physical forces. To explain observed phenomenology, developed generalized clutch model which local stick-slip dynamics cell-matrix adhesions was integrated tissue level through cell-cell junctions. Collective is far more efficient than single-cell durotaxis; it thus emerges as robust mechanism direct during wound healing, cancer invasion.

The extracellular matrix and transforming growth factor-β1: Tale of a strained relationship

Matrix Biology, Journal Year: 2015, Volume and Issue: 47, P. 54 - 65

Published: May 8, 2015

Physiological tissue repair aims at restoring the mechano-protective properties of extracellular matrix. Consequently, redundant regulatory mechanisms are in place ensuring that remodeling terminates once matrix homeostasis is re-established. If these fail, stromal cells become continuously activated, accumulate excessive amounts stiff matrix, and fibrosis develops. In this mini-review, I develop hypothesis mechanical state pro-fibrotic transforming growth factor (TGF)-β1 cooperate to regulate activities cells. TGF-β1 stored as part a large latent complex can be activated by cell contractile force transmitted integrins. Matrix straining stiffening lower threshold for activation increasing resistance pulling. Different elements mechanism pharmacologically targeted interrupt positive feedback loop fibrosis, including specific integrins protein interactions.
