Umbilical Cord Mesenchymal Stem Cells Injection for Ocular Corneal Burn

Placebo-Controlled,Randomized,Double-blind Trial of Umbilical Cord Mesenchymal Stem Cells Injection for Ocular Corneal Burn

Ocular chemical burn is one of the causes of vision loss in China, and there are no satisfactory treatment. Human umbilical cord mesenchymal stem cells(UC-MSCs) have the biological characteristics of self-renewal, immune regulation, multidirectional differentiation and tissue repair. Our preliminary research showed that in corneal alkali injury rabbits, the UC-MSCs can accelerated the cornea repair, inhibited angiogenesis. The aim of this study is to access the efficacy and safety of UC-MSCs in the treatment of corneal burn in human.

Inclusion Criteria:

• must be ocular burns including chemically burned or the thermally burned;
