J Periodontol:脂肪组织来源干细胞用于牙周再生的前景

2020-06-28 MedSci原创 MedSci原创

目前,已经有多种方法用于治疗牙周组织再生,例如引导组织再生,骨移植和生长因子的应用。然而,这些方法的效果存在局限性。随着生物技术和细胞生物学的发展,再生疗法和干细胞的应用为牙周再生提供了广泛的支持。

目前,已经有多种方法用于治疗牙周组织再生,例如引导组织再生,骨移植和生长因子的应用。然而,这些方法的效果存在局限性。随着生物技术和细胞生物学的发展,再生疗法和干细胞的应用为牙周再生提供了广泛的支持。

干细胞是多能的原始细胞,具有分化为多种组织类型的能力。它们的再生潜力必须满足一定的标准才能产生可预测的结果。干细胞必须具备一定的量并通过微创手术获取。它们必须以可重复的方式沿多个细胞谱系途径分化。此外,还需要将干细胞安全有效地移植到宿主中,遵循现行生产操作规程指南。

脂肪组织来源干细胞是牙周再生的潜力细胞来源。这是由于脂肪组织供体的可用性和数量大,部位并发症极少,患者略有不适。皮下脂肪组织为成体干细胞提供了理想的来源,可以通过简单的手术操作获取。包括多种细胞,如前脂肪细胞,成熟脂肪细胞,血管平滑肌细胞,内皮细胞,成纤维细胞和驻留单核细胞/巨噬细胞。

脂肪组织来源干细胞成为牙周再生的重点关注领域。目前,已经对这种相对新型的成体干细胞进行了广泛的研究。将脂肪组织来源干细胞整合到各种临床技术中,发现了它们在动物研究中的有效性,且设计了商用的不同类型的载体,旨在恢复脂肪来源的基质血管成分。

由于一些国家的研究规范不严格,有整形外科医生检测了脂肪组织来源干细胞在伤口护理,瘢痕重塑和缺血控制方面的临床应用。其良好的预后进一步鼓励了临床应用的研究。基于脂肪组织来源干细胞的细胞疗法可以作为一种新疗法,用于处理简单的伤口,以实现完全愈合而不会形成瘢痕。

在牙周缺损的重建和再生范围内,多项动物研究显示,将脂肪组织来源干细胞与富含血小板的血浆结合使用,可通过增强牙周缺损中的骨形成。另外,目前的证据表明,单独使用脂肪组织来源干细胞或与富含血小板的血浆联合使用可提供促进牙周再生的有价值的方法。

由于临床人体研究受到道德和法律法规的限制,需要加强并确保安全的科学研究。在人类中,脂肪组织来源干细胞再生疗法有广阔的前景。
