The typical pathological characteristics of SPTs may result from gradual degenerative changes induced anoxemia in some SPT's areas. The heterogeneity of SPTs on different antibody markers showed that the SPTs may be originated from pancreatic embryonic stem cells, and result from immature differentiation of the pluripotential stem cells during pancreatic genesis.

SPT典型病理特征是由于肿瘤组织不同区域相对缺血、缺氧所造成的退行性变的结果，SPT表达多种组织来源的抗原，反映其可能来源于胰腺干细胞及与其发育密切相关的胚胎神经嵴的神经前体细胞，且在发育过程中发生分化不成熟的结果。

The effects of FPL andits three ingredients on growth of ovary,on micro-and ultra-structure andAlkaline phosphatase activity of endometrium,on structure andkeratinization rate of exfoliated cells in vaginal epithelium in mice,onmicrocirculation in rat and on uterine kinesis in rabbit were respectivelyobserved by the techniques of light and electron microscopes,histochemistry,microcirculation and organ cinetography.The results have confirmed themechanism of FPL for the sterility caused by ovary standstill and persistentcorpus luteum to be as follows:(1) a weak estrogen-like role which canprompt development of ovary,proliferation and secretion of endometrium andvaginal epithelium and cornification of exfoliated cells in vaginal epithelium;(2)enhancing AKP's activity of endometrium;(3)improving microcirculation;(4) exciting uterus.

分别采用光学显微镜和电子显微镜技术、组织化学技术、微循环技术和器官运动描记等现代医学实验技术，观察了促孕液对小白鼠的卵巢发育、子宫内膜的显微和超微结构和碱性磷酸酶活性、阴道上皮结构和脱落细胞的角化率、对大白鼠的微循环和对家兔的子宫运动的影响，结果证实了促孕液治疗卵巢静止、持久黄体的机理：(1)微弱的雌激素样作用，能刺激卵泡发育，促进子宫内膜和阴道上皮增生、分泌和阴道上皮脱落细胞角化；(2)提高子宫内膜碱性磷酸酶的活性；(3)改善微循环；(4)促进子宫运动。

This investigation was to establish a simplified culture system to isolate and passage brain tumor stem cells from human medulloblastoma, observe their proliferation and differentiation, and determine the expression of normal neural stem cell antigens, CD133 and Nestin, in BTSCs. METHODS: Eleven specimens of medulloblastoma were acutely dissociated and triturated into single cells without trypsin digestion.

本研究旨在利用简化的无血清培养基和悬浮培养方法，从人髓母细胞瘤中分离培养脑肿瘤干细胞，观察其在体外的增殖、分化，鉴定其特异性标志物CD133和Nestin的表达，验证肿瘤组织切片中CD133阳性细胞的存在，为脑肿瘤干细胞的进一步研究打下基础。

When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

当氧存在于苹果组织的细胞中时，叶绿体（含有叶绿素和进行光合作用的地方）中的多酚氧化酶，会迅速地将天然存在于苹果组织中的酚类化合物氧化为邻醌。

There was no apparent structure of vasicular bundle sheath in the leaves. Thick cuticle layer was found on both abaxial and adaxial surfaces.

荔枝叶片叶肉组织内细胞的排列，除了在5天叶龄的幼叶排列非常紧密之外，其余叶龄的叶肉组织都会发现有空隙的存在。

子房半下位两性花子房的纵切面，为下方与托杯组织愈合的子房部分，外方细胞较大的为托杯的组织，内方为子房，两者间形成较明显的界线。

BACKGROUND: Research on seed cells is the most important aspect in the filed of tissue-engineering research, and because of their various ad vantages, bone marrow mesenchymal stem cells have been taken as the ideal bone tissue-engineering seed cells.

背景：种子细胞的研究是组织工程众多研究领域中最重要的基础环节，骨髓基质干细胞以其诸多优点，成为理想的骨组织工程的种子细胞。

A generally viscous, yellowish-white fluid formed in infected tissue, consisting of white blood cells, cellular debris, and necrotic tissue.

脓，脓液通常是粘性的，黄白色的，由受感染的肌体组织形成的液体，由白血球，细胞碎片和坏死的组织

Patients developed head cervical lymph node swelling. The lymph node biopsy revealed a background of reactive lymphadenopathy and necrosis in some cases and apoptosis, nuclear debris in all cases, loss of lymph node structure, proliferation of lymphocytes and various types histiocytes with phagocytosis, no infiltration of neutrophils. Three histological types: proliferative, necrotizing and xanthomatous were classified.

形态特征为在活跃的反应性增生淋巴结病变的背景下，出现不同程度的凝固性坏死，淋巴细胞凋亡及核碎片几乎见于所有病例，伴有多种形态的组织细胞增生，吞噬现象明显，无中性杜白细胞浸润，组织学上可分为3型：增生型，坏死型及黄色瘤样型。

Results The expression of DAF was significantly increased in human cervical cancer tissue, and the suppression of DAF expression considerably decreased the migration and proliferation of ME180 cells.

结果 DAF的表达在宫颈癌组织中明显高于其配对的癌旁正常组织，抑制DAF基因的表达能明显降低ME180细胞的增殖、迁移能力。
