    Kinetics of blood cell differentiation during hematopoiesis revealed by quantitative long-term live imaging

    Kevin Yueh Lin Ho, Rosalyn Leigh Carr ... Guy Tanentzapf
    A long-term multi-organ co-culture system coupled with quantitative imaging to visualize blood cell cycle progression, analyze polarized blood cell mitosis, and track blood cell differentiation kinetics during Drosophila hematopoiesis in homeostatic condition and following infection.

    Asymmetric neurogenic commitment of retinal progenitors involves Notch through the endocytic pathway

    Elisa Nerli, Mauricio Rocha-Martins, Caren Norden
    A quantitative live imaging approach unveils that earliest neurogenic progenitors in the vertebrate retina arise from asymmetric divisions and that this asymmetry involves Notch signalling through the endocytic pathway.
