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.
羊膜来源的多能祖细胞似乎可用作伤口愈合的佐剂。羊膜来源的多能祖细胞分泌细胞因子和生长因子的独特组合,称为羊膜来源的细胞细胞因子溶液(ACCS)。在皮肤中,间充质细胞和上皮细胞之间的细胞因子通讯网络严格控制角质形成细胞和成纤维细胞的迁移、增殖和分化,这些是伤口愈合的关键决定因素。为了评估ACCS对角质形成细胞和成纤维细胞迁移行为的影响,使用博伊登小室定量测定细胞迁移。成纤维细胞或角质形成细胞通过膜的趋化迁移活性决定了ACCS的影响。与对照组相比,在ACCS存在的情况下,成纤维细胞和角质形成细胞的迁移在统计学上有显著增加(P < 0.05)。这些对正常伤口愈合至关重要的细胞类型,可能会受到影响而加速在伤口中的迁移,从而加速伤口修复/愈合。
