Study: Mass General successfully restores corneas with patients’ own stem cells | Regen Report

# What exactly was done? 

Researchers at Mass General Brigham’s Mass Eye and Ear did what’s called a cultivated autologous limbal epithelial cell (CALEC) transplantation. 

**English?** The team obtained stem cells from the unaffected eye, expanded them in a laboratory, and transplanted them to the affected eye to regenerate the cornea.

This is the common theme with autologous stem cell therapy. Your body has emergency stashes of stem cells, but sometimes the cells either don’t do their job, can’t reach the area, or don’t exist in the first place, such is the case with USCD. So, doctors will find those cells elsewhere and put them where they need to be.
