Wound healing is a dynamic process, involving the recruitment of growth factors, cytokines, chemokines and cellular populations. Recently, the Cord Blood Platelet Gel (CBPG) has been applied successfully in wound closure and tissue regeneration. Moreover, its proper combination with stem cell populations such as Mesenchymal Stromal Cells (MSCs) may positively improve the wound healing process. Based on the above data, this study aimed to the evaluation of wound healing capacity of MSCs combined with CBPG under in vitro conditions.
Initially, CBPG was developed from Cord Blood Units (CBUs). The determination of wound healing ability of MSCs was performed using the scratch wound assay. In addition, the morphological features, immunophenotypical characteristics and differentiation capacity of MSCs were evaluated.
Scratch wound assay results showed, that CBPG could positively stimulate the MSCs migration. Moreover, MSCs cultured in presence of CBPG were characterized by elongated shape and improved stemness properties as it was indicated by flow cytometric analysis and differentiation process.
These results clearly showed the beneficial effect of CBPG in combination with MSCs in wound healing. The proper combination of CBPG with stem cells strategy may enhance the healing process in patients with skin erosions.
伤口愈合是一个动态的过程,涉及生长因子、细胞因子、趋化因子和细胞群体的募集。最近,脐血血小板凝胶(CBPG)已成功应用于伤口闭合和组织再生。此外,其与间充质基质细胞(MSCs)等干细胞群体的适当组合可能会积极改善伤口愈合过程。基于上述数据,本研究旨在评估 CBPG 与 MSC 联合在体外条件下的伤口愈合能力。
首先,从脐血单位(CBUs)中开发 CBPG。通过划痕实验来确定 MSC 的伤口愈合能力。此外,还评估了 MSC 的形态特征、免疫表型特征和分化能力。
划痕实验结果表明,CBPG 可以积极刺激 MSC 的迁移。此外,在 CBPG 存在下培养的 MSC 表现出伸长的形状,并通过流式细胞术分析和分化过程表明其具有改善的干性特性。
这些结果清楚地表明了 CBPG 与 MSC 联合在伤口愈合中的有益作用。CBPG 与干细胞策略的适当组合可能会增强皮肤糜烂患者的愈合过程。
