Figure Lengend Snippet: Processing of amyloid precursor protein (APP) and glypican‐1 (GPC1) in late endosomes (top) and phosphorylation of cytosolic tau (bottom). β‐NTF and β‐CTF, N‐terminal and C‐terminal APP fragments, respectively; Aβ, amyloid beta peptides; HS‐anMan, heparan sulfate with reducing terminal anhydromannose (blue pentagon); SNO, nitrosothiol; SH, thiol; N =N, molecular nitrogen generated from SNO in the redox reaction; Asc, ascorbate; GPI, glycosyl‐phophatidyl‐inositol; Red squares in tau, microtubule‐binding region; P , phosphate groups. GPC1 is the major, if not exclusive, source of HS‐anMan in human neural progenitor cells and neural stem cells (Cheng et al. , ).
Article Snippet: For dissociation and re‐plating, Accutase (Fisher Scientific Cat. # 11599686) was used as described in detail previously (Cheng et al. ). iPSC‐derived human neuronal progenitor cells (NPC, ATCC, Cat. # ACS‐5003) were plated in CellMatrix gel‐coated plates (Growth kit ACS‐3003 for NPC expansion).
