Spatial and temporal patterns of biochemical signals play a central role in orchestrating the development of multicellular organisms. Such signals, termed “morphogens” 1, have been shown to act ...

Biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body ...

Pattern formation is a central issue in developmental biology. It refers to the process that leads to the spatial arrangement of different kinds of cells in ways that make sense either functionally ...

Morphogens are signaling molecules that are vital for cell differentiation. These molecules directly influence cell differentiation, inducing specific cellular responses in relation to their ...
