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.
Long-term live imaging reveals the dynamic cell behaviors and progenitor cells that underpin the regeneration of adult limbs in the crustacean Parhyale hawaiensis.
Development of a live single-molecule imaging approach to visualize XBP1 mRNAs, which are recruited for translation on the ER and efficiently spliced in the absence of large IRE1α foci.

In vivo single-molecule imaging demonstrates that Smc5/6 chromatin association depends on ATP hydrolysis and dsDNA binding, requires Nse6 and is modulated by Brc1 after DNA damage.
The physical distance between genes in individual cells is the major factor driving co-transcriptional bursts, showing a significant degree of correlation for distances below 400 nm.

Genome editing, advanced live-cell microscopy, and computational modeling were combined to measure WNT/CTNNB1 signaling parameters at the single molecule level, revealing critical regulatory nodes in this important signal transduction pathway.
Chromatin gradually rearranges during epidermal stem cell differentiation, while transcription of a differentiation-associated gene is extremely dynamic.

High-quality fluorescence live-cell and single molecule imaging via computer-controlled, user-assembled microscope that fits in incubator, can in large parts be 3D printed and employs open source software and electronics.
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.
Physical contact between two Myxococcus xanthus cells is sufficient to fuse their outer membrane transiently and exchange outer membrane proteins and lipids at high efficiency.
