Common questions

What is a peptide hydrogel?

A peptide hydrogel is a soft, water-rich material made from short protein fragments that self-assemble into a gel structure. It can mimic the natural environment around cells in the body.

Why mimic the extracellular matrix?

Cells in the body are surrounded by a complex matrix that guides their behavior. By mimicking this matrix with engineered peptide hydrogels, researchers can control cell growth, movement, and function for tissue engineering.
