【正文】 nsplant Used to Treat Children with Cartilage Defect Nature Medicine 5, 309313, March 1999 Bone marrowderived stem cells have been used clinically to treat children with osteogenesis imperfecta, a condition that leads to multiple fractures, severe bony deformities, and considerably shortened stature. Three months after treatment, the three children showed changes indicating new dense bone formation. The report by researchers at St. Jude Children’ s Hospital in Memphis indicates the promising possibility for treatment of this as well as similar stem cell disorders. 61 第六十一頁(yè)，共七十四頁(yè)。 Neural Stem Cells Able to Repair Damage Throughout Brain Sciences USA 96, 70297034, June 8, 1999 In studies with mice, neural stem cells have been shown to globally replace damaged brain tissue. The study, performed by researchers at Harvard Medical School, involved transplanting neural stem cells from born mice into the brains of “ shiverer〞 mice, a model for Parkinson’ s and similar central nervous system diseases. The neural stem cells were able to migrate throughout the brain to repair damaged tissue. Treated mice showed a decrease in tremors. 62 第六十二頁(yè)，共七十四頁(yè)。 Corneal Stem Cells Help Restore Sight New England Journal of Medicine 340, 16971703, June 3, 1999 Corneal stem cells have been used by doctors in Japan to restore useful vision to patients who were legally blind. Transplants of adult corneal stem cells were used for conditions in which normal cornea transplants were unsuitable. One year after treatment, over half of patients had marked improvements in vision. 63 第六十三頁(yè)，共七十四頁(yè)。 64 第六十四頁(yè)，共七十四頁(yè)。 六、干細(xì)胞與組織工程 組織工程是指應(yīng)用工程學(xué)和生命科學(xué)的原理和方法來(lái)研究正?；虿±頎顩r下哺乳動(dòng)物組織的結(jié)構(gòu)、功能和生長(zhǎng)的機(jī)制，研究開發(fā)能夠修復(fù)、維持或改善損傷組織的人工生物替代物的一門學(xué)科。 65 第六十五頁(yè)，共七十四頁(yè)。 組織工程化皮膚 組織工程化骨骼 組織工程化血管 組織工程化管狀器官 組織工程化腺體器官 66 第六十六頁(yè)，共七十四頁(yè)。 67 第六十七頁(yè)，共七十四頁(yè)。 68 第六十八頁(yè)，共七十四頁(yè)。 69 第六十九頁(yè)，共七十四頁(yè)。 70 第七十頁(yè)，共七十四頁(yè)。 七、干細(xì)胞應(yīng)用的法律、 倫理道德問(wèn)題 71 第七十一頁(yè)，共七十四頁(yè)。 [WASHINGTON] The US National Institutes of Health (NIH) could provide funding for research on human embryonic stem cells as early as the spring if new guidelines, published by the NIH last week after widespread public consultation, are formally approved.
