Abstract

Purpose : This study aimed to assess the efficacy of culture media derived from adipose tissue-derived stem cells (CM-ADSCs) for corneal epithelial wound healing compared to platelet-rich plasma (PRP).

Methods : The concentrations of epidermal growth factor (EGF), transforming growth factor (TGF) β-1, and fibronectin of PRP and CM-ADSCs were measured by enzyme-linked immunosorbent assay (ELISA). The efficacies of CM-ADSCs, PRP, and phosphate-buffered saline (PBS) were compared using an in vitro human corneal epithelial wound healing assay. The in vitro human corneal epithelial wounds were 70-μm wide for each well (96-well plate) containing cultured human corneal epithelial cells (HCECs). Following wounding, culture media were replaced with PBS, PRP, and CM-ADSCs, and diluted in corneal epithelial cell basal medium. Wound images were taken every 3h, and the area of the wound was calculated using the ImageJ software.

Results : EGF levels were significantly higher in CM-ADSCs compared to PRP (4253.2 ± 73.7 pg/mL vs. 74.4 ± 2.6 pg/mL, N = 3, P < 0.001). TGF-β1 and fibronectin levels were significantly higher in PRP compared to CM-ADSCs (TGF-β1; 67.8 ± 1.3 ng/mL vs. 3.8 ± 0.1 ng/mL, fibronectin: 285.0 ± 5.4 μg/mL vs. 15.3 ± 0.6 μg/mL, N = 3, P < 0.001, respectively). In the in vitro human corneal epithelial wound healing assay, the CM-ADSCs group significantly promoted wound healing compared to the PBS group and the PRP group (N = 6, P < 0.001, P = 0.020, respectively). In addition, the PRP group significantly promoted wound healing compared to the PBS group (N = 6, P < 0.001). The mean wound closure time was significantly shortened in the CM-ADSCs group (21.0 ± 3.3 hours) compared to the PBS group (55.0 ± 3.1 hours, P < 0.001) and PRP group (26.5 ± 3.5 hours, P <0.001). Wound closure time was also significantly reduced in the PRP group compared to the PBS group (P = 0.003).

Conclusions : CM-ADSCs promoted human corneal epithelial wound healing compared to PRP, suggesting that CM-ADSCs may meet an unmet medical need in the treatment of refractory corneal epithelial disorders.
