Scientists Discover How Heart Muscle Cells Remodel Actin Filaments

Biophysicists unraveled a mystery of how muscles form at the molecular level and how they maintain their function.

Basement Membrane Remodeling Drives Melanocyte Dedifferentiation in Vitiligo Skin Lesions

Vitiligo is an autoimmune disease in which the body's immune system attacks and destroys melanocytes, the cells that produce the skin pigment melanin. Once the melanocytes are gone, the skin turns white, leading to the characteristic skin patches of the disease.

Microtubule-Stabilizing Protein Camsap3 Proves Essential for Female Fertility

Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles.

Rapid Wound Healing in Jellyfish Offers Insights Into How Human Skin Repairs

Jocelyn Malamy first witnessed jellyfish cells "walk" toward each other to close a wound at the Marine Biological Laboratory a decade ago.

Self-Propelled Actin Structures Drive Shape Changes in Human Cells

Every time a white blood cell engulfs a bacterium, a neuron extends a projection to connect with a neighboring cell, or when a cancer cell forcefully squeezes through tissue to spread, the cell must change its shape to accommodate the movement.

Extracellular Acidosis Disrupts Internal Transport Systems of Living Cells

A new scientific study led by the Universidad Carlos III de Madrid (UC3M) describes the mechano-chemical mechanism by which the acidity of the cellular environment destabilizes microtubules, the "avenues" that organize internal cellular traffic.

Essential Keratin Guides Embryonic Cell Movement in Developing Zebrafish

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together as a coherent tissue while modulating the driving forces behind their movement during early development. But what happens when keratin is missing?

New 3D Human Liver Model Mimics Chronic Disease For 30 Days

Researchers developed a 3D liver model that functions for a month, replicating inflammation and fibrosis, crucial for studying liver diseases and therapies.

Scientists Reveal How Cells Translate Force Into Chemical Signals

Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery.

Physics Explains How Neural Tube Closure Occurs in Embryos

In about one out of every 1,000 pregnancies, the neural tube, a key nervous system structure, fails to close properly.

Discovery Challenges the Theory That Proteins Move Mainly by Diffusion

Scientists at Oregon Health & Science University have uncovered a previously unknown system of internal "trade winds" that help cells rapidly move essential proteins to the front of the cell, reshaping how researchers understand cell migration, cancer spread and wound healing.
