The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

Researchers from Osaka University found that plasma cells expressing high levels of the protein integrin β7 and the ...

There is a trial of strength at the cellular level. Cells are in constant competition with each other and so eliminate ...

COVID-19, scientists are watching another virus warily: H5N1. It’s been circulating widely in the U.S. — and now, wild birds ...

Cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health of tissues and organs.

Vaccine effectiveness relies on creating a strong antibody response that can be reactivated to fight future infections. Now ...

Cells can also send out packages called exosomes, lipid vesicles that bubble off from the cell membrane. But for about 20 ...

Vaccine effectiveness relies on creating a strong antibody response that can be reactivated to fight future infections. Now, ...

CD8 + T cells accumulate in atherosclerotic plaques. LMU researchers identify a crucial signaling pathway—with therapeutic potential. For a long time, macrophages and foam cells were considered ...
