Conclusion It is suggested from the present study that the salivary gland tumors may originate from basal cells of intercalary ducts and this cell may closely relate with neural ectoderm. 结论涎腺肿瘤可能起源于涎腺闰管的基底细胞,该基底细胞可能与神经外胚层关系密切。
Tooth development is the result of the interactions between ectoderm epithelium and mesenchyme from neural crest, and tooth root development is regulated by the interactions between HERS and its surrounding ectoderm mesenchyme. 牙齿发育是外胚上皮和神经嵴来源的间充质相互作用的结果,而牙根是在HERS和周围外胚间充质的相互作用下形成的。
