世纪后半叶的分子生物学革命影响了生物医学研究的各个领域。因此,在牙科研究中,这场革命的工具现在可以用来确定启动牙齿萌出的分子信号是什么。什么样的分子发出信号使一个半硬的物体(牙齿)从它的骨隐窝中逃脱,这不仅是一个有趣的分子和发育生物学问题,而且也是一个具有临床意义的问题。了解什么样的分子需要启动正常的牙齿萌出将是巨大的好处,在设计一个分子的方法来刺激萌出阻生牙齿。同样重要的是,将获得这些分子在骨吸收中的作用的知识,因为骨吸收是萌出所必需的(例如,参见Sundquist和Marks,1994; Marks等人,1995年)。在建立牙齿萌出的分子基础之前,必须首先知道萌出所需的细胞和组织,即,信号分子需要作用于什么组织?信号发生在哪个发育时期?由于Marks和Cahill的开创性实验,人们确定,在有限萌出的牙齿中,萌出所需的组织是牙囊,一种在萌出之前围绕牙齿的松散结缔组织囊。他们的研究表明,手术切除卵泡可防止萌出(Cahill和Marks,1980),而保留完整的卵泡但用惰性物体代替牙齿可导致惰性物体萌出(Marks和Cahill,1984)。在细胞水平,单核细胞(单核细胞)流入牙囊,在出生后14周开始在狗第三前磨牙中,并且这种流入在16周达到峰值,这是牙囊发育的开始。
T he molecular biology revolution of the latter part of this century has affected all areas of biomedical research. Thus, in dental research, the tools of this revolution can now be used to establish what the molecular signals are that initiate tooth eruption. Answering the question of what molecule(s) signal a semi-hard object, the tooth, to escape from its bony crypt is not only an intriguing molecular and developmental biology question but also a question of clinical significance. Knowing what molecules are required to initiate normal tooth eruption would be of enormous benefit in devising a molecular approach to stimulating eruption of impacted teeth. Equally significant, knowledge of the role of these molecules in bone resorption will be acquired because bone resorption is required for eruption (e.g., see Sundquist and Marks, 1994; Marks et al., 1995). Before one can establish the molecular basis of tooth eruption, one must first know what cells and tissues are required for eruption-i.e., upon what tissue(s) are the signaling molecule(s) required to act? In what chronological period of development does the signaling occur? Thanks to the pioneering experiments of Marks and Cahill, it was established that, in teeth of limited eruption, a tissue required for eruption is the dental follicle, a loose connective tissue sac that surrounds the tooth prior to eruption. Their studies showed that surgical removal of the follicle prevents eruption (Cahill and Marks, 1980), whereas leaving the follicle intact but substituting an inert object for the tooth results in eruption of the inert object (Marks and Cahill, 1984). At the cellular level, there is an influx of mononuclear cells (monocytes) into the dental follicle, beginning at 14 weeks post-natally in the dog 3rd premolar, and this influx peaks at 16 weeks, which is the onset of
