This undated image provided by Caltech shows a 3-D visualization of fluorescently-labeled brain cells within an intact brain tissue of a rodent. In a study released by the journal Cell on Thursday, July 31, 2014, researchers have described a way to make see-through mice and rats, a step that should help them study fine details of anatomy for basic research.

NEW YORK — Researchers have found a way to make see-through mice, but you won't find these critters scampering in your kitchen.

The transparent rodents aren't alive and they're for research only. They help scientists study fine details of anatomy.

Before the animals are treated with chemicals, they are euthanized and their skin removed. Researchers made their inner organs transparent, but not their bones.

The results look like a rodent-shaped block of gelatin with the organs held in place by connective tissue and a gel used in the procedure.

The work was described in a study released Thursday by the journal Cell.
