Photothermal therapy effects on GNS-ASCs and SKBR3 breast cancer cell co-cultures (scale bars = 100μm). SKBR3 cells were co-cultured with either GNS-ASCs, or ASCs alone (control) for 24 hours and then exposed to a 3.7mW laser for 3 minutes using the MPM. As compared to the unlabeled ASCs, those cells co-cultured with GNS-ASCs demonstrated a clear area of cellular death following treatment. Both samples were stained with fluorescein diacetate and propidium iodide. All images are 1.86 × 1.24 mm2.
