PartⅢExperimental study of autologous BM-MNCs by intramyocardial transplantation into ischemic myocardium of AMI in swines Objective: To evaluate the effectiveness and safety of BM-MNCs by intramyocardial transplantation. Methods: 11 swines were divided into two groups: BM-MNCs group (n=6) and control group (n=5), total 2×10~8 cells.

实验动物分为心肌内移植MNCs组(n=6)及心肌内盐水对照组(n=5)，心肌内移植细胞数2×10~8；移植后4周观察移植细胞归巢情况、小血管密度、心功能及冠脉侧枝血管形成情况及可能发生的副作用。

Cell adhesion and extra cellular matrix in follicles also play an important intraovarian role.

卵泡闭锁的实质就是卵泡中发生了细胞凋亡，其中卵泡颗粒细胞凋亡是导致卵泡闭锁的直接诱因。

FGFR4 expression was faint in renal vesicle and primitive tubules of S-shaped body, irrecognizable in urteric bud and podocyte of C-stage, negative in mesenchyme and condensing mesenchyme.

胚胎肾发生带内FGFR4表达微弱，肾囊泡和S型小体的上支和中间支，即原始肾小管上皮细胞部位有微弱表达，间充质、压缩间充质未见表达，输尿管芽及其末端壶腹和C-期足细胞表达不明显。

After salpingitis tubal atresia adhesion, mucosal cells in the secretion of fluid accumulation within the lumen, or isthmic tubal inflammation and adhesions umbrella side, blocking the formation of fallopian tube, when the lumen is absorbed within the suppurative cells , after eventually become liquid water.

在输卵管炎后，因输卵管粘连闭锁，粘膜细胞的分泌液积存于管腔内；或因输卵管炎症发生峡部及伞端粘连，阻塞后形成输卵管积脓，当管腔内的脓细胞被吸收后，最终成为水样液体。

Ultrastructural observation found more karyopyknosis, abundant cellular organells and increased microvillus within cultured cells.

同时，IP6作用后细胞结构发生改变，出现核固缩、细胞器丰富、微绒毛增多等分化趋势。

A 30 min exposure to peroxynitrite (10〓μmol/L) followed by incubation in fresh medium induced apoptosis in cultured cerebellar granule cells, which was confirmed by DNA laddering, chromatin condensation, nuclei fragmentation, and the formation of apoptotic bodies.

原代小脑颗粒细胞经10μmol/L过氧化亚硝基处理30min，并继续培养一定时间后逐渐发生细胞凋亡，主要表现为DNA链断裂、染色质凝缩、核破裂、形成凋亡小体。

But in day 14th and day 28th groups, the ratio of macrophagus positive area in lung interstitium was bigger than that of control group（ P 〈0.05 ）, with collagen fibers depositing in the lung interstitium gradually.

结论博莱霉素鼠肺毛细血管内皮细胞间紧密连接持续开放，与巨噬细胞在组织间浸润密切相关，并可能是博莱霉素致肺纤维化发生的重要因素。

Merismatic cells mainly derived from the inside of RBM, and belonged to ingenesis. With the ceaseless growth of small cell group, the outer layer cells apop tosis gradually. Finally the buds broke through RBM and became young plants.

芽的分化发生方式属内起源，随着小细胞团的不断生长，外层细胞逐渐凋亡，最终使分化的芽突出再生团块再生成苗。

By spraying polyamines synthesis inhibitors, D-Arg, MGBG (Methylglyoxal bis-guanylhydrazone) and CHA at various concentrations to panicles and flag leaves of indica rice Jinlingxiangnuo (a higher polyamine rice variety) at heading, flowering and grain filling stages, changes in contents and components of PAs in rice grains after harvest were investigated.

多胺(polyamines， PAs)是生物体代谢过程中产生的具有生物活性的低分子量脂肪族含氮碱，是调控生物体生长发育的重要活性物质[1]。PAs在生长发育、细胞增殖、肿瘤发生、编程性细胞死亡(programmed cell death， PCD)、免疫反应及食物过敏症等方面具有重要调节作用[2~6]。

Our results suggest that FGF-2 should be tested for its ability to maintain the reactivity of the nucleus pulposus cells to other morphogenic factors that may be used for cell-based transplantation therapy.

我们的研究说明应该对FGF2保持髓核细胞对其它形态发生因子的反应性从而可能使其应用于细胞移植疗法进行研究。
