A Single-Cell Breakthrough

March 18, 2015 10:35 am | by Marla Vacek Broadfoot, Ph.D. | News | Comments

The human gut is a remarkable thing. Every week the intestines regenerate a new lining, sloughing off the equivalent surface area of a studio apartment and refurbishing it with new cells. This year researchers figured out a way to isolate and grow thousands of these elusive cells in the laboratory at one time.
