This video explains the stages of mitosis, contrasts them with meiosis and the creation of haploid gametes, and concludes by ...

Cell polarity, the asymmetric organization of cellular components, is evolutionarily conserved from unicellular and multicellular organisms and is crucial for many biological processes. Polarity is ...

Tissues are organized through the assembly of diverse cell types into multicellular structures that exhibit hierarchical spatial organization. We present HRCHY-CytoCommunity, a graph neural network ...

The human body and its organs are composed of a wide variety of cell types. Although all cells contain the same genes, they function very differently—partly because protein interactions differ between ...

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of ...

A new tissue expansion method enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. For biologists, ...
