查询词典 placode

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.

Feather growth begins with a thickening of the epidermis called the placode, which elongates into a tube— the feather germ.

首先，表皮上的基板开始增厚，并拉长成一根管子，称为羽芽（上方〈毛的成长过程〉。

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。
