Mimicking mother nature to grow an artificial gland
Using a technique called two-photon microscopy, researchers tracked the movements of embryonic salivary gland cells in real time. The process, budding, occurs many times to drive a gland’s growth into a mature organ that contains thousands of saliva-secreting, globe-like structures.
