mesenchyme造句
1. Influence of mesenchyme Data concerning cellular or molecular stimuli that influence postnatal stem cell function invitro, are scant. 2. Invivo, however, it is likely that only posterior mesenchyme is exposed. 3. Conclusions Neuromuscular tissue of pylorus originates from mesenchyme. 4. Second pharyngeal arch mesenchyme is thus competent to form teeth if provided with the correct signals. 5. Mesenchyme -- embryonic c . t . with multipotential cells . The stellate cells are beginning to form fibers. 6. Thus, it seems embryonic mesenchyme can be replaced with adult stem cells to generate new teeth. 7. Alternatively, indirect effects involving the regulation of epithelial cell function by mesenchyme are also possible. 8. When stem cells from adult bone marrow took the place of oral mesenchyme , for example, the transplanted constructs produced structurally correct teeth. 9. There were lots of tryptase -positive mast cells in the mesenchyme of the human carcinoma tissue of esophagus. 10. Similar sequential and reciprocal interactions between the epithelium and mesenchyme regulate the early steps of development in all ectodermal organs. 11. As the epithelium penetrates farther, it wraps itself around the condensing mesenchyme , eventually forming a bell-shaped structure, open at its bottom, around 14 weeks. 12. In essence, the method requires an understanding of the basic principles controlling early tooth formation and a source of cells to play the roles of embryonic oral epithelium and mesenchyme . 13. Methods:Using spontaneous hypertensive rats (SHR) of different age in months as experiment models to observe the remodeling of myocardium mesenchyme by collagen in quality and quantity. 14. Some of the same epithelial signals that trigger initiation of odontogenesis also regulate an important category of genes in the jaw mesenchyme . 15. Result:At 8-week embryo, trachea consists of 2-3 layers of stratified columnar cells and mesenchyme around the cells, the reaction of PAS of epithelium was positive. 16. The changes, termed 'pathological airway remodeling', affect the epithelium, the underlying mesenchyme and the reciprocal trophic interactions that occur between these tissues. 17. Results:The types of the cardia diseases included carcinoma (21), esophageal varices (14), mesenchyme tissues neoplasm(11) and esophagus hiatus hernia (8). 18. Some researches have shown that BMP -2 is an important signal molecule in the interaction between the epithelium and mesenchyme during embryonic development. 19. CONCLUSION:Nicotine inhibited the BMP secretion of mouse dental germ and dental papilla mesenchyme cells in vitro . 20. The Sharpe group has found that adult mesenchymal stem cells derived from bone marrow( but also possibly obtainable from fat) can replace embryonic mesenchyme in the tooth formation process. 21. Objective High resolution CT (HRCT) was used to observe the microstructure and lesions of lung mesenchyme. 22. We discovered that CAM EC on day 8,10, and 12 after incubation localized beneath the chorionic ectoderm, but with the age growing, EC gradually migrated toward ectoderm from mesenchyme. 23. About 21 days post conception, the primary villi are invaded centrally by allantoic mesenchyme, derived from the embryoblast, transforming them into secondary villi. 24. The low-density areas on CT scan were consistent with the low-density of cells, abundentless nuclei chromatin and vacuoloid changes and microencapsulation in tumor mesenchyme on histology.
