Researchers at the University of Utah have developed a hydrogel that promotes healing by allowing cells to form a matrix. This hydrogel is being used in organ printing, where it helps create 3D grids of living cells that mimic blood vessels or damaged organs. The National Science Foundation sees great promise in this research.

What is the primary function of the hydrogel developed by researchers?

• To provide nutrients to the skin

• To act as a substitute for antibiotics

• To allow cells to form a matrix for healing

• To create a protective layer on the skin

In the context of organ printing, what role does hydrogel play?

• It is used to sterilize medical equipment

• It enhances the growth of existing organs

• It acts as a scaffold for living cells

• It replaces damaged organs directly

How are the living cells arranged in the organ printing process?

• In three-dimensional grids

• In a circular formation

• In random clusters

• In a linear pattern

What is the expected outcome for the cells after being placed in the hydrogel grids?

• They multiply uncontrollably

• They remain inactive

• They form new shapes for implantation

• They dissolve into the gel

Which organization sees great promise in the hydrogel research project?

• National Institutes of Health

• World Health Organization

• American Medical Association

• National Science Foundation
