有必要开发经济、有效和广泛可用的治疗方法来提高皮肤伤口的愈合速度。创面愈合的最佳结果是恢复创面前的健康质量。在这项研究中,我们利用自组装肽RADA16的功能化纳米纤维来研究细胞对生物刺激的反应。我们证明,在RADA16碱基肽中添加不同的功能基序可以影响角质形成细胞和真皮成纤维细胞的增殖和迁移速度。相对于未修改的RADA16;胶原I基序显著促进细胞迁移,减少增殖。
There is a need to develop economical, efficient and widely available therapeutic approaches to enhance the rate of skin wound healing. The optimal outcome of wound healing is restoration to the pre-wound quality of health. In this study we investigate the cellular response to biological stimuli using functionalized nanofibers from the self-assembling peptide, RADA16. We demonstrate that adding different functional motifs to the RADA16 base peptide can influence the rate of proliferation and migration of keratinocytes and dermal fibroblasts. Relative to unmodified RADA16; the Collagen I motif significantly promotes cell migration, and reduces proliferation.
