Mitosis orchestrates eukaryotic cell division, maintaining genetic fidelity and playing a key role in development, tissue homeostasis, and cancer progression.

Scientists have uncovered a key mechanism in jellyfish embryos that provides new insights into how the body plan of these ...

This internal left-right asymmetry is believed to begin at the very early stage of development -- when a tiny embryo is divided into two parts during a process called gastrulation. This process ...

The diagram below shows the same plant cell, as viewed with the light microscope, and with the transmission electron microscope. Animal and plant cells have certain structures in common.

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...

New research reveals that brain cells use a muscle-like signaling mechanism to relay information over long distances.

The new research reveals a novel mechanism for signal transmission in brain cells and helps answer an open question in neuroscience about how intracellular signals travel over long distances in ...

A new study reveals that tau protein affects memory, while beta-amyloid disrupts emotions in Alzheimer’s disease. Using a novel mouse model, researchers found that both proteins interact to worsen ...

Cell biology is the discipline of biological sciences that studies the structure, physiology, growth, reproduction and death of cells. Research in cell biology uses microscopic and molecular tools ...

Recognition of specific antigen through the B-cell receptor (BCR) stimulates the activation of B cells, which ultimately results in the production of high-affinity antibodies and the provision of ...

Many cells in multicellular organisms are specialised. They have specific roles in the organism of which they are part. Their structure is adapted to their function. They are often grouped ...
