The guidance strategy of a cell varies with the chemotactic gradient: in steep gradients, cells produce pseudopodia directly up the gradient, but in weak gradients, pseudopodia are produced at ...

these experiments demonstrate that RAB25 interacts directly with the β1 subunit of α5β1 to maintain a pool of actively cycling α5β1 integrin at the tips of extending pseudopodia. This results ...

Instead of merely extending pseudopodia, as microglia typically do when they eat things, their cell bodies snuggled up to the cells and their processes wrapped the neurons in a bear hug (image above).
