See how the cells accommodate milk production in mouse mammary tissue.

Adipocytes lose their lipids and reprogram themselves into stem cells during lactation, then turn back into fat cells after pups wean.

To improve the resolution of biological samples at the cellular level, researchers inflate tissues with “swellable polymers” so that they’re easier to see under the microscope.
