The development of the calli and single few-celled aggregates was observed through paraffin sections.The results revealed 5 pathways of embryogenic calli origination including origination from both ends of hypocotyls,origination in inner,differentiation from non-embryonic cells,origination from outer cells of calli,and origination in the surrounding of gland.

以陆地棉品种Coker 201下胚轴为外植体诱导愈伤组织，并以介于30-50目筛之间的胚性愈伤细胞团为材料进行单个细胞团培养，采用石蜡切片法观察棉花愈伤组织诱导和分化过程及体细胞胚发生和发育过程。

Immunohistochemistry were positive for CD34 in some region where the fibroblast actively proliferated, whereas fibrocytes in mature fibrous tissue were negatively stained.

CD34免疫组织化学染色显示一些增生活跃的纤维母细胞明显表达CD34，成熟的纤维组织内的纤维细胞CD34则为阴性。

Product of Homeobox gene is identified as a class of transcription regulator, whose functions include not only controlling cellular development and differentiation, but also regulating other gene expression in the adult.

同源框基因表达产物作为一类重要的转录调节因子，不仅在组织发育和细胞分化方面起重要的作用，而且在成年的组织和细胞中也参与其它基因的表达调控。

Methods Fifteen healthy, female SD rats were employed in the experiment. Sensitized systematically with keyhole limpet hemocyanin, the animals were inoculated with the same antigen through cochlea basal turn into the labyrinth. Adminstrated 5-bromo-2′-deoxyuridine intraperitoneally, the rats were sacrificed and the temporal bones were harvested at 3, 7,14 day after labyrinth vaccination respectively. The frozen sections of the decalcified samples were dealt with H-E staining and immunohistohemical methods to investigate the cellular infiltration, BrdUrd and IgG positive cells in the ES.

选用SD大鼠15只，以钥孔虫戚血蓝蛋白（keyhole limpet hemocyanin，KLH）全身免疫后，经耳蜗底回钻孔以相同抗原进行内耳免疫，然后分别在内耳免疫后3、7和14 d腹腔注射溴脱氧尿嘧啶核苷（bromodeoxyuridine，BrdUrd）后处死动物，取颞骨经组织学处理制作冰冻切片，用免疫组织化学技术观察内淋巴囊的细胞浸润、增殖和IgG细胞的分布状况。

The results showed that the number of TILs was varied greatly from case to case in untreated NPCs, the infiltrating lymphocytes within carcinoma was mainly T cell, no B cell.

结果表明，各种淋巴类细胞在癌组织中的分布差异很大，在组织中浸润的细胞主要是T淋巴细胞。
