Only just noticed this one, although it was published in Stem Cells online last month.
Another beautiful demonstration of the healing power of our own stem cells – here, patients with limbal stem cell deficiency (LSCD) had some residual limbal stem cells sampled, multiplied in a culture (that excluded any animal products) and reimplanted in sufficient numbers to help regenerate the patient's own damaged cornea. All patients gained better vision and reduced discomfort.
