Figure 4. Phagocytosis rate versus the interfacial free energy of adhesion.

Figure 4

(A) S. epidermidis 3399, (B) S. epidermidis 7391, (C) S. epidermidis 1457, (D) S. aureus ATCC 12600GFP, (E) S. aureus 7323, and (F) S. aureus LAC. Note that phagocytosis rates increase when the interfacial free energy of adhesion becomes more favorable (more negative), but phagocytosis is not ruled out by unfavorable surface thermodynamic conditions (shaded regions). Dashed lines indicate the best-fit to a linear function through the data.
