Laser ablation
- The enteric nervous system in zebrafish larvae can regenerate via migration into the ablated area and proliferation of neural crest-derived cells
Summary: Study of neurite and neural crest-derived cell behavior during regeneration of the zebrafish enteric nervous system provides a basis for its research in vivo at single-cell resolution in vertebrates.
- Automated cell tracking identifies mechanically oriented cell divisions during Drosophila axis elongation
Summary: Using body axis elongation in Drosophila embryos as a model, novel image analysis and machine learning methods identify cell divisions oriented by mechanical cues to reduce strain.
- Phyllotaxis involves auxin drainage through leaf primordia
Highlighted article: Leaf positioning follows a stereotyped pattern controlled by auxin distribution. Auxin drainage via the incipient midvein of leaf primordia contributes to this patterning.
