This report presents microscopic observation on morphological and immuno- cytochemical characteristics of the trophoblast cells of the human decidua at the implantation site in the first trimester pregnancy .The infiltration of a unique type of large cells different from cytotrophoblast (CT) and syncytotrophoblast (ST) was found in the decidua at the implantation site. These unique cells are termed inter- mediate trophoblast (IT). They are typically mononucleate, but may be binucleate or multinucleate. The mononucleate cells vary in shape from round, polyhedral spindle shaped. Their cytoplasm is typically abundant and eosinophilic or amphophilic. The nuclei may vary in size and shape. These cells usually distribute around the spiral arterioles, differse blood vessel wall, penetrate into the lumen, and even replace the blood vessel wall totally. Immunocytochemically, both these cells and ST are stained positive for HCG and HPL. However, the HCG-stained Cell population of IT.is much lower than that of ST,while the of HPL stained cell population of IT is significantly higher than that of ST.On the other hand,neither HCG nor HPL are positive in CT. The results of SP-1 ?-HCG usually go with those of HCG.in CT, ST and IT.The PAPP-A gives non specific staining result. It is believed that IT,with its distinct morphological and immunocytochemical feats,is regarded as a transitional form in the shift from CT to ST.

Objective To detect the expression of stem-cell related factors Nanog and CD44 in spheroid body-form?ing cells of gastric cancer cell line MKN-45. Methods The gastric cancer cell line MKN-45 was used to culture spheroid bodies in non-adherent condition in a serum-free medium supplemented with epidermal growth factor (EGF) and basic fibro?blast growth factor (bFGF). Using Western blot analysis, immunofluorescence staining and quantitative real time polymerase chain reaction(qRT-PCR), the expression levels of stem cell-related genes Nanog and CD44 were studied. Results In this study, we observed that MKN45 cells formed spheroid bodies in non-adherent condition in a serum-free medium, and the levels of Nanog and CD44 mRNA expression in spheroid body-forming cells were 2.34 ± 0.22 and 1.18 ± 0.04,respectively, which were higher than those in parental cells (1.00±0.00 and 1.00±0.05). The levels of Nanog and CD44 protein expression in spheroid body-forming cells were 0.18±0.02 and 0.24±0.04, respectively, which were significantly higher than those in pa?rental cells (0.07±0.02 and 0.18±0.01, P<0.05). Nanog protein was positively stained within the perinuclear and cytoplasm of the spheroid body-forming cells, and CD44 was positively stained mainly in the membrane. Dual staining of Nanog/CD44 indicated that the embryonal protein Nanog was co-localized with CD44 in the spheroid body-forming cells. Conclusion Spheroid body-forming cells developed from human gastric cancer cell line MKN-45 in serum-free medium supplemented with EGF and bFGF show characteristics of cancer stem cell (CSC). The cells co-expressed of CD44 and Nanog maybe a phe?notype of gastric CSCs.

AIM: The present study was to investigate the time course of ?-adrenoceptor desensitization and changes in the calcium transient in rat ventricular myocytes following chronic hypoxia. METHODS: With the spectrofluorometric method, the intracellular calcium( i) transient and its response to ?-adrenoceptor stimulation were determined in the single right ventricular myocytes, loaded with Fura-2.RESULTS: After 2-3 weeks of chronic hypoxia, the amplitudes of electrically induced i transient and caffeine-induced i transient started to decrease and the duration of i transient prolonged. The enhanced electrically induced i transient evoked by isoprotrenol was also decreased. After 3 or 4 weeks of chronic hypoxia, these changes aggravated gradually. After 8 weeks of chronic hypoxia, the changes of all these parameters were convalescent, meanwhile there was no significant difference compared with that of 4 weeks group. CONCLUSIONS: After 2-4 weeks of chronic hypoxia, the ?-adrenoceptor desensitization occurs, the underlying mechanism is related to the decreased function of L-type of calcium channel, ryanodine receptor-operated calcium channel and calcium ATPase, which is responsible for the decreased cardiac functionl. At 8 weeks of hypoxia, the heart is in adaptation and compensatory process.
