This graphic illustrates paracrine adhesion signaling on small extracellular vesicles, which secretes a protein called galectin-3, which promotes endocytosis so the vesicle can be absorbed into the ...

The numerous cells that make up mammalian tissues are surrounded by an intricate network of proteins known as the extracellular matrix (ECM). Together, these proteins provide cells with a structural ...

As a human embryo grows, a set of molecules directs cells as they multiply and take on specific identities and spatial positions within the embryo. In one crucial step known as gastrulation, these ...
