Chromatin gradually rearranges during epidermal stem cell differentiation, while transcription of a differentiation-associated gene is extremely dynamic.
UV irradiation, a major cause of skin damage, leads to selective loss of fibroblasts from the upper dermis via a deregulated inflammatory response, and infiltrating T cells can promote fibroblast survival in UV irradiated skin.
Genetic lineage tracing approach combined with live imaging visualized the functional stem cell activity of Doublecortin-like kinase 1+ cells within pancreatic cancer in vivo.

Lifetime imaging of endogenous metabolic coenzymes is sensitive to dynamic changes in macrophage activation in a live animal, providing a label-free imaging approach to study immunometabolism in vivo with single-cell, spatial, and temporal resolution.
An improved culture method for explanted adult Drosophila organs allows the live-imaging of damage response, cell differentiation, and tracing of progenitor cell lineages through multiple rounds of division.

Building on previous work (Grotjohann et al., 2012), low-light super-resolution microscopy has been performed on living transgenic Drosophila larvae and tissues.

Axonal arborisation growth is regulated by dynamic, focal localisations of Neurexin and Neuroligin that provide stability for filopodia, enabling a 'stick and grow'-based mechanism, wholly independent of synapse formation.

ADeS, a novel deep learning approach for apoptosis detection, achieves 98% accuracy in vitro and in vivo while providing unprecedented insights into the spatial–temporal foundation of cell death.

Ig domain family members DIP-alpha and Dpr10 are required in a subset of Drosophila leg motor neurons and muscles, respectively, to establish their fine terminal branching pattern and synapses.
A new platform for imaging live Drosophila adults yields vivid movies of the midgut over prolonged time scales, opening the door to the real-time study of organ renewal dynamics in a near-native context.
