Grizzly bears' strategy could help prevent muscle atrophy in humans

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal "Scientific Reports", a team led by Michael Gotthardt reports on how they manage to do this.

Study provides better understanding of mechanisms that limit cilia number in cells

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes.

A HSC surface marker plays key role in ontogeny of hematopoiesis

A group of researchers at Osaka University revealed that ESAM (Endothelial cell-selective adhesion molecule), a surface marker for hematopoietic stem cells (HSCs) and vascular endothelial cells (ECs), played an important role in the ontogeny of hematopoiesis in mice, particularly in the development of adult-type erythropoiesis.

Scientists identify molecular mechanisms that protect cells against mechanical stress

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the molecular mechanisms that allow our cells to adapt to, protect themselves against, and survive mechanical stress.

Study reveals new role for a triple-negative breast cancer target

Unlike almost every other organ, the mammary gland does not develop until after birth. And it's unusually dynamic, shape-shifting during menstrual cycles, puberty, pregnancy, and lactation.

Researchers discover new way to supercharge protein production

Medicines such as insulin for diabetes and clotting factors for hemophilia are hard to synthesize in the lab. Such drugs are based on therapeutic proteins, so scientists have engineered bacteria into tiny protein-making factories.

Brazilian researchers create hepatic organoids by 3D bioprinting

Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids ("mini-livers") that perform all of the liver's typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others.
