Neonauclea reticulata (Havil.) Merr Stimulates Skin Regeneration after UVB Exposure via ROS Scavenging and Modulation of the MAPK/MMPs/Collagen Pathway

Figure 4

Viability (%) of human foreskin fibroblasts exposed to Neonauclea reticulata extract. Neonauclea reticulata extract (5–200 μg/mL) did not exhibit cytotoxic effects on the proliferation of cells. In addition, the preparations at high concentration (>100 μg/mL) stimulated cell growth (150%) (***𝑃<0.001).
