Biology: Scientists grow human tear glands in the lab that are capable of CRYING just like real eyes


Usually, no one wants things to end in tears unless they are the experts who have successfully grown miniature human tear glands in the lab that cry like real eyes. 
The team from the Netherlands grew the organoids to investigate how certain cells in tear glands allow us to keep our eyes clear and lubricated, as well as get all weepy.
Located in the upper part of the eye socket, tear glands secrete tear fluid, which is made of water, proteins, lipids and electrolytes.
However, tear glands can fail to work properly in people with certain conditions such as Sjogren s syndrome, which also affects the production of saliva. ....

Stem-cell-derived organoids that swell up with tears could shed light on the biology of crying and dry-eye disease, suggests a study publishing March 16 in the journal
Cell Stem Cell. Although regenerative therapies using human tear-gland organoids will not be possible anytime soon, these researchers have demonstrated that the organoids can engraft, integrate, and produce mature tear products upon transplantation into mouse tear glands.
We hope that scientists will use our model to identify new treatment options for patients with tear-gland disorders by either testing new drugs on a patient s organoids or expanding healthy cells and, one day, using them for transplantation, says senior study author Hans Clevers (@HansClevers) of the Hubrecht Institute. ....
