Celleutstikk, a term originating from Norwegian, translates literally to "cell sticking" or "cell protrusion." It describes the phenomenon where a cell extends a portion of its plasma membrane to form a temporary projection. These protrusions can take various forms, including filopodia, lamellipodia, and pseudopodia, each with distinct structural and functional roles.
Filopodia are thin, finger-like extensions that are highly dynamic and rich in actin filaments. They are often
The formation and retraction of these cellular protrusions are tightly regulated processes involving a complex interplay
