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.
The identification of key determinants of LSC “stemness” and LSC differentiation that is reversible through an epigenetic mechanism may have considerable implications in understanding leukemia and designing effective therapies.
The requirement for WNT signaling in mesendoderm differentiation is temporally separate from that of ACTIVIN signaling and acts to switch the output of ACTIVIN/SMAD2 from pluripotency maintenance to mesendoderm patterning.
Heterogeneous epidermal stem cells define a niche for tactile sensation via providing a unique ECM and tissue architecture for nerves, revealing their new functions in coordinated sensory organ formation.

A bioengineering approach identifies tissue morphology as an effective variable for controlling the inception of neural organoid morphogenesis via induction of a biomimetic, singular neural rosette tissue cytoarchitecture.
Sequential live imaging of abnormal skull bone fusion in zebrafish reveals a deeply conserved role of two transcription factors, Twist1 and Tcf12, in regulating stem cell activity during growth of the skull.
Modulation of muscle stem cell redox state in culture both improves their amplification while maintaining a similar grafting potential as freshly isolated stem cells.
Dynamic control of intrinsic pluripotent multicellular self-organization to yield robust symmetry breaking patterns that recapitulate morphogenic processes associated with developmental events.
Ablation of the Cdkn1c cell cycle inhibitor leads to defective muscle stem cell dynamics and myogenic potential, while progressive cytoplasmic to nuclear cellular localization of the Cdkn1c protein regulates growth arrest.

High levels of nuclear YAP are sufficient to drive squamous cell carincoma formation and frequently also drive progression to spindle cell carcinoma by promoting epithelial-to-mesenchymal transition after tissue damage.
