    Cerebral Organoids Derived from Patients with Alzheimer’s Disease with PSEN1/2 Mutations Have Defective Tissue Patterning and Altered Development

    Scientists demonstrated that cerebral organoids derived from three Alzheimer’s disease (AD)-iPSC lines with PSEN1(A246E) or PSEN2(N141I) mutations developed the AD-specific markers in vitro, yet they also uncovered tissue patterning defects and altered development.

    Abstract

    Using Picoliter Droplet Deposition to Track Clonal Competition in Adherent and Organoid Cancer Cell Cultures

    Investigators demonstrated a novel experimental approach, based on multi-color, fluorescent tagging of cell nuclei, in combination with picoliter droplet deposition, to study the clonal dynamics in two- and three-dimensional cell cultures.
