Fig 1. Euglena extract reduces lipid accumulation in hASCs.

(A) Effect of Euglena extract on cell viability. The confluent hASCs were cultured in D/α (-) medium with water (white circles) or Euglena extract (black circles) for 2 days at 37°C under 5% CO₂ atmosphere before WST-8 assay. (B) Microscopic images of hASCs stained with Oil Red O. (C) and (D) Relative abundance of accumulated Oil Red O in hASCs treated with water (C) or Euglena extract (D) compared with control (no additive, dark grey bar in (C) and (D)). Data represent the mean ± SEM from 3 independent experiments. *P <0.05 (Student’s t-test).
