Human Adipose-Derived Stem Cells for the Treatment of Chemically Burned Rat Cornea: Preliminary Results
2013
AbstractPurpose: Adipose-derived stem cells (ADSC) are multipotent, safe, non-immunogenic and can differentiate into functional keratocytes in situ. The topical use of ADSC derived from human processed lipoaspirate was investigated for treating injured rat cornea.Methods: A total of 19 rats were used. Six animals initially underwent corneal lesion experiments with 0.5 N NaOH (right eye) and 0.2 N (left). The 0.2 NaOH protocol was then used in 13 rats. All 26 eyes of 13 rats eyes received topical azythromycin bid for 3 d and divided into five treatment groups (n = 5 eyes/group), which included: control, stem cells, serum, stem + serum and adipose (raw human lipoaspirate). The four treatment groups received topical treatment three times daily for 3 d. Stem cells were isolated and harvested from human lipoaspirate. Topical eye drops were prepared daily with 1 × 105 cells/treatment. Fluorescein positive defect area and light microscope assessment was performed at 20, 28, 45, 50 and 74 h. Animals were sacrific...
