文题释义:
LED红光:
是由发光二极管发出的光,波长为600-700 nm,属于不相干单色光源。LED光是一种寿命长、转化效能高的光,具有不良反应小、节省费用等优点,能影响细胞的生长及分化、增加细胞因子的分泌。此外LED光还具有治疗部分临床疾病的作用,如促进伤口愈合。
细胞增殖:是细胞生命活动的重要特征之一,机体创伤愈合、组织再生、病理组织修复都依赖细胞的增殖。细胞增殖的检测方法主要包括3H-TdR、MTT、CCK-8、WST-1等。实验采用MTT检测LED红光对两种干细胞增殖的影响。这种检测方法较为简便、灵敏,方法较为可靠。

 

摘要
背景:
光生物调节是一种新型治疗方案,LED红光能否影响牙源干细胞增殖,是探索颌面部再生治疗新方案的关键。
目的:比较不同光照能量LED红光对人牙周膜干细胞与人根尖乳头干细胞增殖的影响。  
方法:分离培养、流式鉴定获取人牙周膜干细胞和人根尖乳头干细胞。MTT法检测不同光照能量0,1,3,5 J/cm2对两种牙源性干细胞增殖的影响。
结果与结论:①非光照下根尖乳头干细胞增殖速度较牙周膜干细胞更快,1,3,5 J/cm2 LED红光均能促进两种牙源性干细胞增殖;②LED红光能促进牙周膜干细胞缓慢增殖期和对数生长期(1-7 d)增殖,其中5 J/cm2对早期影响最明显,后期1 J/cm2增殖作用最强;③LED红光对根尖乳头干细胞对数生长后期(5-7 d)影响较明显,3 J/cm2 LED红光的增殖作用于第7天达到峰值;④根据人牙周膜干细胞和人根尖乳头干细胞对LED红光的时效依赖及量效依赖性,选定特定的光照能量及时间,可快速有效地促进细胞增殖。

Abstract:

BACKGROUND: Photobiomodulation is a new treatment option. Whether red light-emitting diodes can affect the proliferation and regeneration of dental stem cells is the key to exploring new treatments for maxillofacial regeneration.
OBJECTIVE: To compare the effects of red light-emitting diodes with different light energies on the proliferation of human periodontal ligament stem cells and apical papillary stem cells.
METHODS: Periodontal ligament stem cells and apical papillary stem cells were isolated and cultured by flow cytometry. Proliferation of these cells was detected using MTT assay after exposure to red light-emitting diodes at different light energies (0, 1, 3, and 5 J/cm2). 
RESULTS AND CONCLUSION: Apical papillary stem cells proliferated faster than periodontal ligament stem cells under non-lighting environment. Red light emitting diodes at 1, 3, and 5 J/cm2 promoted the proliferation of two kinds of odontogenic stem cells. The red light-emitting diode promoted the proliferation of periodontal ligament stem cells at proliferative and logarithmic growth phase (1-7 days). And 5 J/cm2 red light emitting diode had the most obvious effect in early stage, and 1 J/cm2 had the strongest effect in the late stage. The red light-emitting diode had a significant effect on the logarithmic growth (5-7 days) of apical papilla stem cells, and under 3 J/cm2 red light-emitting diode the proliferation peaked on the 7th day. Therefore, the red light-emitting diode can promote the proliferation of human periodontal ligament stem cells and apical papillary stem cells in dose- and time-dependent manner. Exposure to red light-emitting diode at proper energy and time can promote cell proliferation quickly and effectively.

Key words: apical papillary stem cells, periodontal ligament stem cells, odontogenic stem cells, red light-emitting diode, cell proliferation, light energy, photobiomodulation
