Several cell lines derived from periodontal membrane, dental pulp, inner enamel epithelium and bone marrow of BALB/cA mouse were established. When the enamel epithelial cells were cultured in the growth medium supplemented with the products of human dental pulp cells, the enamel epithelial cells produced ameloblastin. The pellets of ameroblastin producing cells and dental pulp cells were inserted into the collagen gel adjoining each other. Then these constructions were enveloped with human periodontal membrane. Lastly, they were enveloped with collagen sponge and cultured GM supplemented with the ETFs by circumfusion apparatus.We established 27 tissue stem cell lines derived from human bone marrow. Three of them made teratoma when they were transplanted into the subcutis of nude mouse. The stem cells were cultured by hanging drop method with ETFs, the embryoid bodies were developed. The embryoid bodies were brought up with ETFs to the embryo-like structures by circumfusion apparatus. However, there is nothing of the tooth germ structures yet.

建立了BALB/cA小鼠牙周膜、牙髓、内釉上皮和骨髓细胞系。当釉上皮细胞在添加人牙髓细胞产物的生长培养基中培养时，釉上皮细胞产生成釉蛋白。将产非成纤维细胞和牙髓细胞的颗粒插入彼此邻接的胶原凝胶中。然后用人牙周膜包裹这些结构。最后，用胶原海绵包被，在体外循环仪上培养含ETFs的GM，建立了27株人骨髓组织干细胞系。其中3株移植于裸鼠皮下形成畸胎瘤。用ETFs悬滴法培养干细胞，获得拟胚体。用ETFs将胚状体通过灌流装置培养成胚状结构。然而，目前还没有关于牙胚结构的研究。
