The main advantages of the one-stage technique are the preservation of the dental papillae and the timely formation of a gingival sulcus during the integration of the implant. 单程技术有利之处在于植体融合时期中,保护植体乳头以及促进齿沟之形成。
The effect of TGF-β 1 on proliferation of porcine dental papillae cells ( pDPCs) in vitro TGF-β1对猪牙乳头细胞体外增殖的影响
However, the use of human odontoblasts and/ or ecto-mesenchymal cells from dental papillae for basic research and therapeutic purposes has been restricted partly by their limited proliferative potential that they could divide about ten times before fully exiting the cell cycle and becoming senescent and dead. 然而,人牙乳头组织来源的牙乳头外胚间充质细胞和(或)成牙本质细胞在通常的体外培养条件下经过十余次的传代后,就会停止分裂增殖,发生衰老和死亡。
AIM: To observe the expression of GDNF in tooth germ and dental papillae mesenchymal cells. 目的:观察胶质源性神经营养因子(GDNF)在人牙胚和体外培养的人牙乳头间充质细胞中表达部位及其表达变化。
RESULTS: The porcine dental papillae cells were well cultured in vitro. The DSP, collagen ⅰ, collagen ⅲ were positive expressed. 结果:在上述实验条件下,成功培养了猪牙乳头细胞,免疫组化检测到DSP、Ⅰ型胶原、Ⅲ型胶原呈阳性表达。
Localization of glial cell line-derived neurotrophic factor in human tooth germ and cultured dental papillae mesenchymal cells 胶质源性神经营养因子在人牙胚和体外培养的人牙乳头间充质细胞中表达的实验研究
BMP was expressed in the ameloblast, the intermedium stratum cell and the stellate reticulum cell but not in dental papillae cells or odontoblast. 成釉细胞,中间层细胞和星网状层细胞均有BMP表达,牙乳头细胞或成牙本质细胞不表达BMP。
