摘要:While preparing the final article, a large portion of the text in the Results section titled ‘‘Integrina11b1Protein Levels Regulate the Spreading of MSFs on Soft Matrices’’ was erroneously deleted from the proof text and thus missing from the published article. The deleted text impacted nearly the entire second paragraph of this section. The missing text has since been reinstated, and Cell Press production sincerely apologizes for any confusion it may have caused.
