Microscopic Anatomy of Skeletal Muscles

22.8K
Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction.
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...

Electron Microscope Tomography and Single-particle Reconstruction

2.9K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.9K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

What are Cells?

198.8K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

What is Cell Signaling?02:03

What is Cell Signaling?

130.3K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Area of Science:

  • Developmental Biology
  • Genomics
  • Cell Biology

Background:

  • Understanding adult mammalian cell differentiation is crucial for regenerative medicine and disease research.
  • Existing methods often lack the resolution to capture dynamic cell identity changes in real time.

Purpose of the Study:

  • To elucidate adult mammalian cell trajectories in real time using novel imaging and sequencing techniques.
  • To investigate the process of intestinal enteroendocrine differentiation and identify novel lineage features.
  • To uncover the roles of specific transcriptional regulators in cell fate determination using organoid models.

Main Methods:

  • Integration of single-cell transcriptomics with dynamic two-color fluorescence imaging.
  • Real-time monitoring of cell differentiation in adult mammalian systems.
  • Utilisation of organoid cultures to study cell identity and gene regulation.

Main Results:

  • Detailed mapping of cell trajectories during adult mammalian intestinal enteroendocrine differentiation.
  • Identification of previously unrecognized lineage features and dynamic shifts in cell identity.
  • Functional validation of identified transcriptional regulators in organoid experiments.

Conclusions:

  • The combined approach provides unprecedented real-time insights into cell fate determination.
  • New understanding of enteroendocrine cell development and regulation.
  • Organoid systems are powerful tools for dissecting gene function in differentiation processes.
