Many factors may be involve in the course. To investigate the regulation activity of mesenchymal cells to differentiation of epithelial cells from hair follicle and to study its differentiation property, mesenchymal cells gel was made by nubby dermal papilla cells, free dermal papilla cells, skin fibroblasts. Skin keratinocytes and epithelial cells from hair follicle were inoculated on the gel surface and cultured in air-liquid interface. Three-dimensional model of DPC using to induce epithelial cells differentiation is built in vitro.

为了进一步研究毛囊细胞间的相互作用，探讨毛囊间质细胞对毛囊上皮细胞分化的调节作用，研究毛囊上皮细胞的分化特性，我们利用团块状的毛乳头细胞，游离分散的毛乳头细胞或皮肤成纤维细胞制成间质细胞胶原凝胶，表面接种皮肤角质形成细胞或毛囊上皮细胞，进行气-液界面培养，在体外建立了毛乳头细胞诱导毛囊上皮细胞分化的立体模型。

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.

结果青钱柳叶表皮有许多小乳突，腺毛，盾状鳞片和非腺毛表皮毛；气孔器不规则型，仅分布于下表面；靠近表皮的叶肉组织中有规律地分布含簇晶的细胞；主脉中维管组织环状，封闭，具有一个副维管束；二级脉在叶缘内分支，相互连接形成脉环，三级脉及顶型，脉间区内充满分支的自由结束的小细脉。

Ovary superior; carpels 2, connate, stalked, 1-loculed, glabrous or piliferous, placentation parietal; ovules 2 to numerous, anatropous; style 1, hairy; stigma capitate, shallowly lobed.

子房上位。心皮2，合生，柄，1，具毛的无毛或，侧膜胎座；胚珠2到多数，倒生；花柱1，有毛；柱头头状，浅裂。

Plants with 1(or 2) lines of hairs on stems or basal margin of leaves and nodes, not pilose or stellate hairy.

植株具1(或2)线状毛在茎或叶和节的基部边缘上的，并非具柔毛的或星状毛。

Stems sparsely pilose and pubescent, or densely rigidly hairy in lower part.

浓密刚硬的茎疏生柔毛和短柔毛，或有毛的在下部。

In China, Pimpinella can be divided into two groups: those species with hairy, puberulent, or distinctly roughened fruits and obsolete calyx teeth; and those with smooth, glabrous fruits and obsolete or conspicuous calyx teeth.

在中国，Pimpinella 可以被分成两组：有毛，被微柔毛的，或果明显粗糙和萼齿废退的；以及那些具平滑，无毛果和废退的或明显的萼齿的。

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。

Branchlets glabrous or puberulent; leaf blades 15–20 × 5–7 mm; follicles glabrous.

小枝无毛或者被微柔毛；叶片 15-20 * 5-7 毫米；蓇葖果无毛。
