Figure 3. Fiber-cell interactions with increasing short fiber dosage.
Fiber-cell interactions quantified by flow cytometry reveal a dose-dependent increase in all interactions for short fibers. The relative percentage of cells with internalized interactions compared to total interactions was relatively unchanged for all fiber doses, with 36.4%, 35.7%, and 34.9% for short fiber doses 5, 10, and 20 respectively. A total of 10,000 cells were counted including cells with no associated fibers.
