    Summary
    This summary is machine-generated.

    Calcium ions are key regulators of cell shape changes during tissue development and evolution. Understanding intracellular calcium balance is crucial for controlling morphogenetic movements in embryogenesis and evolution.

    Area of Science:

    • Developmental Biology
    • Cell Biology
    • Evolutionary Biology

    Background:

    • Morphogenesis, the generation of tissue form, is vital for both embryogenesis and evolutionary divergence.
    • Cell shape changes, driven by microfilaments and microtubules, underlie morphogenetic movements.
    • Intracellular calcium levels regulate microfilament contraction in non-embryonic systems.

    Purpose of the Study:

    • To investigate the role of intracellular calcium in controlling morphogenetic movements.
    • To explore calcium's involvement in embryogenesis and evolutionary changes in form.

    Main Methods:

    • Perturbing cellular calcium balance.
    • Directly measuring intracellular calcium ion concentration.

    Main Results:

    Related Experiment Videos

    • Evidence suggests calcium is involved in key morphogenetic events like gastrulation and neurulation.
    • Calcium also plays a role in related processes such as wound healing.

    Conclusions:

    • Intracellular calcium ion balance is a critical control mechanism in morphogenesis.
    • Fundamental questions regarding morphogenesis in embryogenesis and evolution can now be addressed through calcium signaling research.
