Appendix 1—figure 5. Chronic exposure of JUUL for 3 months does not induce fibrosis in the liver, heart, and kidney.

Appendix 1—figure 5.

Collagen deposition was quantified by image analysis (using ImageJ) of lung histological slides stained with Masson’s trichrome. Representative pictures are shown for liver tissue in (A) Air control, (B) JUUL Mango, (C) JUUL Mint and (D) Quantification of collagen percentage in liver tissue. Representative pictures for heart tissue are shown in (E) Air control, (F) JUUL Mango, (G) JUUL Mint and (H) Quantification of collagen percentage in heart tissue. Representative pictures for heart tissue are shown in (I) Air control, (J) JUUL Mango, (K) JUUL Mint and (L) Quantification of collagen percentage in kidney tissue. Data for quantification is presented as individual data points ± SEM with n = 4–6 mice per group.
