Rainbow Ribbons of Collagen, Jennifer Davis and Alexandra Berr

Collagen is a protein that provides shape and support to organs, providing a scaffold for living cells to grow and thrive. It is also the most abundant protein in the human body.

This image shows collagen fibers in a lung tumor from a mouse. When arranged in a specific way, the fibers glow when illuminated with infrared laser light. This image is color-coded by depth to reveal the fibers’ three-dimensional structure. This work helps investigate how processes like cancer and aging affect collagen.
