Supplementary Fig. 3. Immunofluorescence staining of iPSC pluripotent stem cell protein markers. The iPSCs derived from wild-type (WT) control and NCL patient fibroblasts were stained for the pluripotency markers of SOX2, SSEA4, TRA-1-60, Nanog and Oct4. The images were taken with 20X objective lens.

Supplementary Fig. 4. Protein marker expression in NSCs derived from WT control and NCL patient iPSCs. Representative images showed positivity for NSC marker proteins of Nestin, Sox1, Sox2 and PAX6. These NCL NSCs showed no morphological differences compared to WT control NSC cells. The images were taken with 20X objective lens.

Supplementary Fig. 5. Enlarged lysosomes and lipid accumulation in NCL patient fibroblasts. Increased LysoTracker dye staining (A) indicates enlarged lysosomes and a strong Nile Red staining (B) indicates lipid accumulation. Enlarged lysosomes and lipid accumulation were observed in parental fibroblasts (FIB) of NCL patients compared to wild type (WT) control. Representative images of LysoTracker dye and Nile Red staining were shown with 20X objective lens. Quantification of the lysoTracker staining(C) and Nile Red staining (D) revealed significantly enlarged lysosomes and lipid accumulation in NCL patient fibroblasts. Data are displayed as mean ± SD. ** P < 0.01 vs. WT control.

Supplementary Fig. 6. Filipin staining in NCL fibroblasts and NSCs. Representative images of Fillipin staining (A) showed no free cholesterol accumulation in patient NCL fibroblast and NSCs. A quantification of cholesterol accumulation in fibroblasts and NSCs was found no statistically significant (B). NPC1 patient fibroblasts and NSCs were used to serve as the positive control for Filipin staining. Data are displayed as mean ± SD. ** P < 0.01 vs. WT control.

Supplementary Fig. 7. Cytotoxicity of δ-tocopherol (DT) and HPBCD on NCL patient NSCs. Cytotoxicity of DT (A) and HPBCD (B) was measured by an ATP content assay. DT lower than 20 uM concentration has no cytotoxic effect on all four NSCs cell lines. HPBCD showed no significant cytotoxic effect up to 1 mM concentration after a 3-day treatment period in those cells except for one of the NCL patient cell line, TPP1E4/IVS5, which decreased the cell viability by 64.2%

Supplementary Fig. 8. Lysosomal pH indicated by a pHrodoTM PH sensor dye in NCL patient NSCs. Representative images of pHrodoTM dextran staining (A) after 3-day treatment of DT and HPBCD. A quantification of pHrodoTM dextran fluorescence signal showed no significant lysosomal pH changes except for 40 μM of DT treatment, which showed small decrease of fluorescence intensity (B), possibly caused by the cytotoxic effect of high concentration of DT as indicated by the cell cytotoxicity assay. Data are displayed as mean ± SD. *** P < 0.001, compared to the untreated control.
