Abstract

Background

Amnion-derived multipotent progenitor (AMP) cells, unlike most stem cells, have been demonstrated to be nontumorigenic and nonimmunogenic. Amnion-derived cellular cytokine solution (ACCS), a secreted product of AMP cells, is a cocktail of cytokines existing at physiological levels and has been used to accelerate epithelialization of experimental partial-thickness burns.

Methods

Using modifications of Zawacki’s guinea pig partial-thickness scald burn model, a total of 65 animals were treated with ACCS, ACCS + AMP cells, unconditioned medium (UCM) + AMP cells, or either UCM alone or saline as controls. Dosage times ranged from every other day to once a week. Percent epithelialization was serially determined from acetate wound tracings. Histology was performed on wound biopsies.

Results

ACCS, UCM + AMP cells, and ACCS + AMP cells improved epithelialization compared with the two control groups (P < 0.05). When ACCS was delivered more frequently, statistically significant more rapid epithelialization occurred (P < 0.05). By day 7, all groups treated with ACCS had reached at least 90% epithelialization, whereas control groups were only 20–40% epithelialized (P < 0.05). Histology showed excellent regeneration of the epidermis with rete ridge formation. Hair growth occurred in ACCS-treated animals but not in the control group.

Conclusions

Amnion-derived cellular cytokine solution accelerates the healing of experimental partial-thickness burns. Based on these findings, a multicenter clinical trial is underway.
