Distinct Contact Guidance Mechanisms in Single Endothelial Cells and in Monolayers

Supplementary Figure 10 from Claire Leclech et al. (2023) “Distinct Contact Guidance Mechanisms in Single Endothelial Cells and in Monolayers”: Characterization of the secreted basement membrane. (C) Surface topography and stiffness (Young’s modulus) obtained by atomic force microscopy of the secreted ECM or bare PDMS after 72 h of culture on flat surfaces coated with fibronectin (FN) or poly-L-lysine (PLL). Dots represent individual measures on n=2 independent experiments. Error bars represent standard deviations. Please follow the link to the full article to find the full supplementary figure 10 and its description. Atomic Force Microscopy measurements were performed using an AFM probe with circular symmetric rounded AFM tip with typical radius of curvature around 30 nm (0.03–0.09 N m−1) (uniqprobe qp-BIOAC-CI, from NANOSENSORS).

In many tissues, cell shape and orientation are controlled by a combination of internal and external biophysical cues. * Cell shape is closely controlled in… Read More »Distinct Contact Guidance Mechanisms in Single Endothelial Cells and in Monolayers
