RESULTS: NK cells represent a unique subset of lymphocytes that have no restriction by MHC antigens and have the ability to lyses certain tumor cells without the requirement for prior immune sensitization of the host. In addition, NK cells can also produce cytokines and regulate the function of other immune cells. So, it is emerging to apply NK cells as therapeutic agents against a broad range of malignancies. In this respect, the anti-tumor activity of NK cells is the key factor of NK-cell-based immunotherapy.

结果：NK细胞是一种独特的淋巴细胞，对靶细胞的识别无MHC限制性，无需预先致敏即可直接杀伤肿瘤细胞，也可分泌细胞因子调节其他免疫细胞的功能，是机体天然免疫的主要承担者，也是获得性免疫的核心调节细胞，故NK细胞在抗肿瘤免疫中的地位越来越受到重视，随之增强NK细胞肿瘤杀伤活性的研究也逐步深入。

Some of transplanted cells expressed titin and the assembled titin could be detected in the cells adjacent to host myocardium. Cx43 could be observed between these cells. But the size and structure of transplanted cells were different from normal contractile myocardium.3. Most of the grafted cells were isolated by fibrous tissue. Part of these cells differentiated into fibrocytes. The structure of host myocardium was slightly disturbed.

MSCs植入正常心肌组织后能存活至12周，部分移植细胞表达titin，且与宿主心肌细胞相邻的细胞表达titin组装程度更高，随时间延长表达逐渐明显，其后进入平台期，但细胞体积及胞浆发育均不及正常心肌细胞；在移植细胞与宿主细胞之间可检测到Cx43的表达。

Total RNAs from KAx-3 cells and AK127 cells(developed for 14h) were isolated. After the reverse transcription and PCR reaction, two distinct differential fragments were acquired., fragment A was from KAx-3 cells and fragment C was from AK127 cells. After retriving and reamplifying the differentially expressed fragments, white-blue plaqueselection, the fragments were purified. Northern blot proved that fragment A was from KAx-3 cells and fragment C was from AK127 cells. The results of sequencing and researching for NCBI database have been showed: part sequence of fragment A shows 91% similarity to the gene encoding DhkA, 92% similarity to the gene encoding DhkF, 91% similarity to the gene encoding STATc, 97% similarity to the homoeobox gene encoding protein. These genes play important part in controlling cell differentiation and cell proportion in Dictyostelium discoideum.

本研究通过提取盘基网柄菌发育14小时的野生型KAx-3细胞和突变型AK127细胞的总RNA，运用mRNA差异显示法分离出了两条明显的差异表达片段，其中片段A来自野生型KAX-3细胞，片段C来自突变型Ak127细胞；并通过凝胶回收差异片段、对差异片段进行再次PCR、蓝白斑筛选克隆、提取质粒、酶切电泳纯化差异片段；接着进行Northern杂交的结果表明，片段A只与野生型KAx-3细胞的总RNA有杂交信号，片段C只与突变型AK127细胞的总RNA有杂交信号，这就排除了差异片段假阳性的可能；最后通过测序，搜索NCBI BLAST数据库发现：片段A的小部分序列与编码组氨酸激酶DhkA基因中一段序列的相似性高达91%，与编码组氨酸激酶DhkF基因中的一段序列相似性高达92%，与编码STATc蛋白基因的一段序列相似性达91%，以及与编码同源框蛋白的基因中的一段序列相似性达97%，这些基因在盘基网柄菌细胞分化和细胞比例调控过程中起着相当重要的作用，这些数据进一步说明了突变细胞不能完成发育的原因。

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy（32/120; 26.7%）. The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders（22/120; 18.3%）. Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found（12/120; 10%）. Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters（8.3%）. Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters（4.2%）had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.

Combined with the previous studies on artificial taste and cell-based biosensor in our laboratory, we provides a novel taste cell chip based on LAPS since taste receptor cells are excitable similar to neurons.

味觉受体细胞具有神经细胞特性，也属于可兴奋性细胞，将其培养在LAPS芯片表面，味觉细胞电位的改变即可通过检测LAPS的光生电流得以测量。

Indeed, it seems that each taste bud contains taste cells responsive to each of the different taste categories!

事实上，几乎可以说每个味蕾对於不同的味道都能起反应！

Taste cells are cultured on the LAPS chip for several days and then the change of extracellular signals can be detected by measuring the change of LAPS photocurrent. Compared with MEA and FET array, LAPS chip is easier to fabricate and allows us to track taste cells cultured randomly and locate it to desirable site taking advantage of light-addressability of LAPS.

与MEA和FET阵列芯片相比，LAPS芯片不仅制各工艺简单，而且其光源可移动寻址，方便对芯片表面随机培养的细胞进行跟踪定位，克服了MEA和FET阵列芯片固定检测位点几何特性的限制。

Our results demonstrate: The structures of the organs are normal, and the shapes of cells are clearly visible. There are lots of positive brown granules in Chief cells and Parietal cells in abomasum as well as the mucosa epithelial cells and gland cells of duodenum. Three bands with a molecular mass close to 120KDa、110KD and 98KDa were identified by Western Blot. The Ob-R levels of 120KDa in abomasum were significantly higher than that of in small intestine. The levels of 110KDa were similar in the two organs. The expression of 98KDa Ob-R was weak.
