Cell Size

Cell Size

Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.
Surface Area
Cells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding the cells limits the...

Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...

Determining the Plane of Cell Division

Determining the Plane of Cell Division

Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.
Animal cells
In animal cells, the cleavage furrow forms along the plane of cell division starting...

Background:

Spatial gene expression patterns are crucial for development, operating at various scales.
Existing spatial transcriptomics tools have limitations in resolution or field of view.
Understanding large-scale spatial gene expression is key to deciphering developmental processes.

Purpose of the Study:

To introduce sci-Space, a novel method for high-resolution spatial transcriptomics over large areas.
To analyze spatial gene expression patterns and cellular heterogeneity in developing mouse embryos.
To enable the construction of spatially resolved single-cell atlases of mammalian development.

Main Methods:

Development and application of the sci-Space technique.
Capturing approximate spatial coordinates and whole transcriptomes of single nuclei.
Analysis of gene expression patterns, cellular subtypes, and migratory behaviors.

Main Results:

sci-Space resolved spatial heterogeneity at larger scales while retaining single-cell resolution.
Thousands of genes showed anatomically patterned expression in developing mouse embryos.
Spatial information aided in annotating cellular subtypes and revealed varying degrees of spatial patterning across cell types.
Correlations were found between developmental pseudotime and neuronal migratory patterns.

Conclusions:

sci-Space overcomes limitations of previous methods, enabling large-scale spatial transcriptomics.
The study provides novel insights into gene expression patterns and cellular dynamics during embryonic development.
This technology is poised to significantly advance the creation of spatially resolved developmental atlases.
