Fig. 2From: Piperine improves the sensitivity of osteosarcoma cells to doxorubicin by inducing apoptosis and inhibiting the PI3K/AKT/GSK-3β pathwayEffect of PIP combined with DOX on scratch healing in osteosarcoma cells. Cells were scratched using a 100 μL tip and then treated with PBS, PIP, DOX, and PIP + DOX. Scratch healing was observed at 0, 12 and 24 h after scratching.
