    Glycan Epitopes on 201B7 Human-Induced Pluripotent Stem Cells Using R-10G and R-17F Marker Antibodies

    Investigators developed two hiPSC/hESC-specific glycan-recognizing mouse antibodies, R-10G and R-17F, using the Tic hiPSC line as an antigen. R-10G recognized a low-sulfate keratan sulfate, and R-17F recognized lacto-N-fucopentaose-1.

    Overlapping Roles of JIP3 and JIP4 in Promoting Axonal Transport of Lysosomes in Human iPSC-Derived Neurons

    Investigators established a hiPSC-derived neuron model for the investigation of axonal lysosome transport and maturation and showed that loss of JIP3 resulted in the accumulation of axonal lysosomes and the Alzheimer’s disease-related amyloid precursor protein-derived Aβ42 peptide.
