Ice crystals form along cells' seamlike structures

Detailed view of ice forming in cells could lead to better tissue preservation

Slow-motion video showing how cells freeze may help scientists preserve tissue without damaging it.

Ice is more likely to form in tissue cells that are frozen together than in cells chilled individually. By watching cells freeze under a cryomicroscope, researchers were able to determine that ice crystals spread along seamlike structures that weave together neighboring cell membranes in tissue. The seams normally seal cells to keep ice out. But at low temperatures, ice crystals can poke through...
