Amnion-derived cellular cytokine solution (ACCS) promotes migration of keratinocytes and fibroblasts.

Amnion-derived Multipotent Progenitor cells appear to be useful as adjuvants in wound healing. Amnion-derived multipotent progenitor cells secrete a unique combination of cytokines and growth factors, known as amnion-derived cellular cytokine solution (ACCS). In the skin, a cytokine communication network between mesenchymal and epithelial cells tightly controls keratinocyte and fibroblast migration, proliferation and differentiation-key determinants of wound healing. To evaluate the influence of ACCS on the migratory behavior of keratinocytes and fibroblasts, cell migration was assayed quantitatively using a Boyden chamber. Chemotactic migration activity of fibroblasts or keratinocytes through the membrane determined the influence of ACCS. In the presence of ACCS, fibroblasts and keratinocytes demonstrated a statistically significant (P < 0.05) increase in migration when compared with controls. These cell types, critical to normal wound healing, may be influenced to accelerate migration in wounds, thus accelerating wound repair/healing.
