Meanings of ecm rigidity in English

For select AR, mitochondria were also smaller as ECM rigidity increased.

On some substrates, a-actinin volume increased with cell AR but was not affected by ECM rigidity.

Collectively, these results suggest that mitochondrial architecture in cardiac myocytes is strongly influenced by cell shape and moderately influenced by ECM rigidity.

In this study, we tested the hypothesis that cell aspect ratio (AR) and ECM rigidity regulate the architecture of the mitochondrial network in cardiac myocytes.
