Precision vibratome for high-speed ultrathin biotissue cutting and organ-wide imaging

iScience, 2021
Summary: Cutting tissues into ultrathin slices is highly desired in sectioning-based organ-wide imaging. However, it is difficult to perform tissue cutting at a high speed with excellent quality.

A light-switching pyrene probe to detect phase-separated biomolecules

iScience, 2021
Summary: Biomolecules may undergo liquid–liquid phase separation (LLPS) to spatiotemporally compartmentalize and regulate diverse biological processes. Because the number of tools to directly probe LLPS is limited (ie. FRAP, FRET, fluorescence microscopy,

Multiplexed protein profiling reveals spatial subcellular signaling networks

iScience, 2022
Summary: Protein-protein interaction networks are altered in multi-gene dysregulations in many disorders. Image-based protein multiplexing sheds light on signaling pathways to dissect cell-to-cell heterogeneity, previously masked by the bulk assays ...

SkewC: Identifying cells with skewed gene body coverage in single-cell RNA sequencing data

iScience, 2022
Summary: The analysis and interpretation of single-cell RNA sequencing (scRNA-seq) experiments are compromised by the presence of poor-quality cells. For meaningful analyses, such poor-quality cells should be excluded as they introduce noise in the data.

Specificity and efficiency of tamoxifen-mediated Cre induction is equivalent regardless of age

iScience, 2023
Summary: Temporally controlling Cre recombination through tamoxifen (Tam) induction has many advantages for biomedical research. Most studies report early post-natal/juvenile (12 m.o.).

3D visualization of trans-syncytial nanopores provides a pathway for paracellular diffusion across the human placental syncytiotrophoblast

iScience, 2022
Summary: The placental syncytiotrophoblast, a syncytium without cell-cell junctions, is the primary barrier between the mother and the fetus. Despite no apparent anatomical pathway for paracellular diffusion of solutes across the syncytiotrophoblast ...

A non-invasive method to genotype cephalopod sex by quantitative PCR

iScience
Summary: Coleoid cephalopods (cuttlefish, octopus, and squid) are emerging model organisms in neuroscience, development, and evolutionary biology and are of major economic importance in global fisheries.

Direct capture and sequencing reveal ultra-short single-stranded DNA in biofluids

iScience, 2022
Summary: Cell-free DNA (cfDNA) has become the predominant analyte of liquid biopsy; however, recent studies suggest the presence of subnucleosomal-sized DNA fragments in circulation that are likely single-stranded.
