The epidermis dominant the changes. Mesenchymal is subordination.β-catenin expression begin from placode epidermis stage and go up increasingly as well as peak value maintain to hair follicle. The range of mesenchymal change is less. SHH expression transform is dramatically to stimulate the placode-germ-peg-hair follicle.

结果表明，在睫毛毛囊的形态发生中表皮－间充质相互作用以表皮为主导间充质随着表皮而变化，β-catenin从基板表皮开始表达，逐渐增强，从毛芽至形成毛囊维持高水平，间充质变化幅度较小；Shh则在睫毛形态发生中变化剧烈，刺激基板－毛芽－毛钉－毛囊。

Catenin was detected in suprabasal, epidermal basal layer, placode, hair bud in early phase(E68～93),and expressed strongly in epidermal basal layer, placode, and hair bud, in suprabasal expressed less strongly; in metaphase(E94～184),β-catenin was detected in epidermis, hair peg, and in suprabasal, epidermal basal layer, hair follicle bulge, inner root sheath, outer root sheath, follicular infundibulum expressed less strongly; in late phase(E184～225),β-catenin expressed weakly in epidermal basal layers, while expressed strongly in epidermal keratinocytes.

结果显示：β-catenin在胎牛蹄边缘毛囊形态发生早期(68～93天)表达于表皮、基底层、基板和毛芽中，其中基底层、基板、毛芽中呈强阳性，表皮中呈中阳性；在毛囊形态发生中期(94～184天)表达于基底层、表皮和毛钉中，其中基底层、表皮、隆突区、内外根鞘和漏斗部呈中阳性；在毛囊形态发生晚期(184～225天)只在表皮及基底层有表达，其中基底层呈弱阳性，表皮呈强阳性。

MethodsNeural tubes isolated from the region between midotic placode and third somite of mouse embryo at ED 8.5d were cultured in DMEM/F12 serum-free medium containing basic fibroblast growth factor and epidermal growth factor. The cell cycle of CNCCs was analyzed with flow cytometry, the proliferation capability was determined by MTT method, AP-2α expression was detected by immunocytochemistry as a biological marker of cardiac neural crest cells. The features of migration, multi-directional differentiation were observed as well.

材料与方法成年2月龄C57／BL6小鼠交配，取ED8.5d小鼠胚胎枕中部至第3体节神经管，应用包含碱性纤维生长因子和表皮细胞生长因子的无血清培养基培养，利用MTT法检测细胞增殖能力，利用流式细胞仪检测细胞周期，采用转录激活因子2α(AP-2α，Activator protein-2α)作为其生物学标记物，观察其增殖状况、细胞周期、迁移、分化等生物学特性。

鱼类通过一些细小的感受器-神经丘(neuromast)[16]感受水流变化,这些神经丘排列成线列于鱼体侧皮下,从100多个表皮细胞(被称为体侧线原基细胞,英文:Primodium)分化而成,从耳后基板(Placode)排列直至尾部.
