Shape descriptors of adhesion area.

<p>Comparison of projected area per adhered cell, elongation, and circularity of 1AS cells on supported membranes functionalized with poly-HA and oligo-HA at <<i>d</i>> ∼ 5.5 nm and <i>t</i>  =  2 h. Standard deviation is given for mean values of nine cells for each condition.</p>
