Bristle worms, known for their self-assembling bristles, utilize specialized cells called chaetoblasts that function like microscopic 3D printers, depositing chitin layer by layer to form intricate structures. This natural process provides valuable insights into cellular regeneration and holds promise for developing advanced biomedical materials.

The chaetoblasts' microvilli, acting as biological nozzles, precisely control chitin deposition, enabling the formation of complex bristle designs. Understanding this mechanism could revolutionize the creation of biodegradable surgical materials and inspire innovations in regenerative medicine.

Remarkably, bristle worms can regenerate most of their bodies, a feat that continues to intrigue scientists exploring the parallels between these marine organisms and human regenerative processes.
