Methods: Rat MSC was isolated and purified in vitro,labelled by Hoechst33342, stereotaxis imbed into CA4 of rat hippocampus.

近来研究发现，MSC可以分化为神经元样细胞、胶质样细胞等［1］，植入体内后对脑和脊髓的损伤性疾病有治疗作用［2］，为MSC替代治疗神经系统疾病提供了实验基础。

Its pathology change is tiny stone often accompanies the kitchen sex that has prostate, chronic inflammation changes, stone is big person prostate canal and gland bubble dilate, there is size to differ all round, appearance the bursa antrum of each different, clinking skin cell covers its wall, between gland bubble soak of cell of form having garden and fiber are changed, stone can be located in gland to run mouth office, yi Ke is in gland body deep, the person that affect for a long time.

其病理变化是微小的结石常伴有前列腺的灶性，慢性炎症变，结石大者前列腺管和腺泡扩张，周围有大小不等，形状各异的囊腔，其内壁无上皮细胞覆盖，在腺泡间有园形细胞浸润及纤维化，结石可位于腺管开口处，亦可在腺体深部，长期感染者。

The progress of studies on Stylosanthes in the aspects of stylo anthracnose caused by the fungus Collectotrichum gloeosporioides and its genetic diversity and epidemiology, breeding, cytogenetics, cytobiology, tissue culture, protoplasm fusion, gene clone, genetic transformation, classification and molecular makers was reviewed in this paper.

We found significant differences in the patterns of cytokines elicited by accination (where IFN- was by far a subdominant response) s natural infection; in addition, there was fairly significant intersubject ariation.

我们发现疫苗接种诱发的细胞因子(其中，IFN-是最强的亚优势应答)和自然感染诱发的细胞因子的模式有显著性差异；此外，还有相当显著的因子间的变异。

Aim: In order to investigate the distribution and clonality of TCR Vet subfamily T cells in cord blood.

目的：了解正常脐血中T细胞受体Vα亚家族T细胞的分布和克隆性情况。

Methods Hela cells of human cervical cancer were cultured with mitomycin C in gradually increased dosage in order to obtain a drug-resistant Hela/MMC cell subline. The biological properties of Hela and Hela/MMC cells were compared and the mechanism of drug-resistance of Hela/MMC cells studied.

以人宫颈癌Hela细胞为亲本，采用丝裂霉素连续性药物作用，间隙性增加药量，逐步提高药物浓度的方法，分离出MMC耐药亚系，并比较两种细胞生物学特性差异。

A human osteosarcoma cell subpopulation with spontaneous highly pulmonary metastasis is established in nude mice.

结论该细胞亚群是一株新建立的人骨肉瘤细胞高转移性亚系。

Objective: To investigate the suppressive and regulatory function of CD4+CD25+ regulatory T cells in adoptive immunity of the patients with colon cancer.

目的 探讨CD4+CD25+调节性T细胞在直肠癌过继免疫治疗中对免疫杀伤细胞的负性调节作用。

The result showed that the plant of Maicao No. 9 was tall, with good fecundity, fully filled grain and vigorous growth. The chromosome number of the root cells was 2n=56, through the observation of pollen mother cells meiosis, there were a certain amount of univalents, ring bivalents and bar bivalents in PMCM. Different numbers of lagging chromosomes, chromosome bridges and micronucleus were found in anaphaseⅠ, anaphaseⅡ and tetraspore.

结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。

Cells on a biomaterial surface usually respond to three main categories of physicochemical cues: chemically, topographically, and mechanically. In this study, mechanical property of a particularly-prepared chitosan film was modified to improve its cell affinity.

而细胞受生物基材表面的物理化学讯号影响，主要可分为三类：化学、形貌和机械性质，本研究以修饰特别制备的几丁聚醣膜表面性质来改善细胞亲和性。
