The impact of inflammatory response on the biological characteristics of GMSCs has been the subject of studies, with conflicting findings. In order to more fully understand the effects of the localized inflammatory environment, the current study assessed the intensity and differentiating capacity of GMSCs derived from healthy periodontal tissues (H-GMSC) and GMSC derived from inflamed periodontal tissues (I-GMSC) tissues. Cells from every well were taken out and counted using a hemocytometer every three days for a total of 12 days. The findings of the cell proliferation assay, which involved quantifying the cells with the help of a hemocytometer at 0th day, 3rd day, 6th day, and 9th day, are shown. On day nine of culture, there was a considerable (P = 0.02) variation in the rate of multiplication between GMSCs from healthy gingival tissues and GMSCs from gingival tissues having inflammation. Additionally, I-GMSCs had a higher cell concentration on day twelve than that of H-GMSCs. However, there was no significant variance in PDT values comparing GMSCs from healthy gingival tissues and GMSCs from gingival tissues having inflammation (P > 0.05). The mean PDT findings of 66.7 h and 53.4 h have been documented for Healthy-GMSCs and Inflamed-GMSCs, respectively. In addition, compared to GMSCs from healthy gingival tissues, GMSCs from inflammatory tissues had decreased osteogenesis and increased adipogenic potential. To evaluate the efficacy of GMSCs derived from patients suffering periodontitis utilising human models for cell-based treatments, additional study is necessary.
炎症反应对牙龈间充质干细胞生物学特性的影响一直是研究的主题,但结果相互矛盾。为了更全面地了解局部炎症环境的影响,本研究评估了源自健康牙周组织的牙龈间充质干细胞(H-GMSC)和源自炎症牙周组织的牙龈间充质干细胞(I-GMSC)的增殖强度和分化能力。每隔三天从每个孔中取出细胞,使用血细胞计数器进行计数,共持续12天。展示了细胞增殖试验的结果,该试验涉及在第0天、第3天、第6天和第9天借助血细胞计数器对细胞进行定量。在培养的第9天,来自健康牙龈组织的牙龈间充质干细胞与来自有炎症牙龈组织的牙龈间充质干细胞之间的增殖率存在显著差异(P = 0.02)。此外,I-GMSC在第12天的细胞浓度高于H-GMSC。然而,比较来自健康牙龈组织的牙龈间充质干细胞和来自有炎症牙龈组织的牙龈间充质干细胞的群体倍增时间值时,没有显著差异(P > 0.05)。健康牙龈间充质干细胞和炎症牙龈间充质干细胞的平均群体倍增时间结果分别记录为66.7小时和53.4小时。此外,与来自健康牙龈组织的牙龈间充质干细胞相比,来自炎症组织的牙龈间充质干细胞成骨能力下降,成脂潜能增加。为了利用人体模型评估牙周炎患者来源的牙龈间充质干细胞用于基于细胞的治疗的疗效,还需要进一步研究。
