Histogen theory A theory, proposed by Hanstein, in which the apical meristem is considered to consist of three main zones, the dermatogen, periblem, and plerome, which differentiate into the epidermis, cortex, and stele respectively.

组织原学说：是由 Hanstein 提出的理论，认为顶端分生组织是由三个主要区域组成，表皮原、皮层原和中柱原，随后它们各自分化为表皮，皮层和中柱。

In roots, however, the concept is still applied, and in some angiosperm roots a fourth histogen zone is recognized, the calpytrogen, which gives rise to the root cap.

然而在根中，它还是适用的。在一些被子植物的根中，还发现了第四种组织原，即 calpytrogen ，与根冠发生有关。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Methods Specimens of neurofibroma tissue, keloid and normal skin were collected. The distribution and expression of CTGF was measured by immunohistochemistry. The mRNA expression of CTGF, TGF-β1,ColⅠ and ColⅢ was detected by reverse transcription- polymerase chain reaction. Expression of CTGF protein was measured by western blotting.

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.

The promeristem is consisted of three groups of initial cells, which have typical cytological characteristics of meristem cells. The primary meristem is composed of calyptrogens, primordial epidermises, periblems and pleromes. Both the calyptrogens and the primordial epidermises initiate from the same layer of initial cells.
