An atlas of cortical arealization identifies dynamic molecular signatures

The human brain is subdivided into distinct anatomical structures, including the neocortex, which in turn encompasses dozens of distinct specialized cortical areas. Early morphogenetic gradients are known to establish early brain regions and cortical areas, but how early patterns result in finer and more discrete spatial differences remains poorly understood. Here we use single-cell RNA […]

Quantification of gene expression changes in mouse disease models using a high-throughput spatial omics platform

Batch effects due to technical variability are a major problem in single cell transcriptomics. Spatial methods are no exception – their low throughput requires high numbers of technical replicates, reducing the statistical power needed to quantify differential gene expression across experimental conditions. To overcome this problem, we took advantage of the large imaging area of […]

Multibeam Interferometric Illumination as the Primary Source of Resolution in Optical Microscopy

In conventional light microscopy, the physics of lenses impose relations between resolution and other optical parameters of the system. For example, the numerical aperture of a lens cannot be increased to improve resolution without either increasing the size of the lens or decreasing the working distance. The technique presented here, Synthetic Aperture Optics (SAO), removes […]

DIGIT is a Conserved Long Noncoding RNA that Regulates GSC Expression to Control Definitive Endoderm Differentiation of Embryonic Stem Cells

Long noncoding RNAs (lncRNAs) exhibit diverse functions, including regulation of development. Here the authors combined genome-wide mapping of SMAD3 occupancy with expression analysis to identify lncRNAs induced by activin signaling during endoderm differentiation of human embryonic stem cells (hESCs). They found that DIGIT is divergent to Goosecoid (GSC) and expressed during endoderm differentiation. Using single […]

lncRNA DIGIT and BRD3 Protein Form Phase-separated Condensates to Regulate Endoderm Differentiation

Cooperation between DNA, RNA and protein regulates gene expression and controls differentiation through interactions connecting regions of nucleic acids and protein domains and through the assembly of biomolecular condensates. In this study, the authors used StellarVision, a Synthetic Aperture Optics-based imaging system, to measure interactions between DIGIT, a long non-oding RNA, and BRD3, a protein […]

Mutations in the Promoter of the Telomerase Gene TERT Contribute to Tumorigenesis by a Two-step Mechanism

Mutations in the promoter region of the gene coding for the reverse transcriptase component of telomerase (TERT) are found at high frequency in various human tumor types. These TERT promoter mutations (TPMs) have been detected both in early- and late-stage tumors, consistent with the possibility that they play a role early in tumorigenesis. SAO-based imaging […]

Validating scRNAseq Data from Human Fetal Brain Using Automated, Highly Multiplexed in situ mRNA Detection with Single-cell and Single-transcript Resolution

Single-cell RNA sequencing (scRNA-seq) has fundamentally expanded our understanding of tissue composition and heterogeneity. While this methodology enables unbiased and comprehensive identification of distinct cell types based on their transcriptomic profiles, it does not provide positional context in the tissue architecture, which is critical for understanding the interactions between cells and their native tissue microenvironment.
