‘Therapy using tissue-specific stem cells’ begins with haematopoietic stem cell transplantation (HSCT), which is considered the most important type of stem cell therapy. HSCT covers the transplantation of bone marrow and other types of transplant where the blood-forming stem cells of the graft come from non-marrow sources. It is used mostly for the treatment of leukaemias and lymphomas. Some genetic diseases of the blood have also been successfully treated using allogeneic HSCT. There are also other examples of cell therapy using tissue-specific stem cells, such as epidermal cells for the treatment of burns and limbal (corneal) stem cells for treatment of eye injuries.
“使用组织特异性干细胞的治疗”始于造血干细胞移植(HSCT),这被认为是最重要的干细胞治疗类型。造血干细胞移植包括骨髓移植和其他类型的移植,其中移植物的造血干细胞来自非骨髓来源。它主要用于治疗白血病和淋巴瘤。使用同种异体造血干细胞移植也成功地治疗了一些血液遗传疾病。还有其他使用组织特异性干细胞进行细胞治疗的例子,例如用于治疗烧伤的表皮细胞和用于治疗眼部损伤的角膜(角膜)干细胞。

7. Expectations: realistic and unrealistic 7. 期望:现实和不现实

‘Expectations: realistic and unrealistic’ contemplates the goal of biomedical sciences to regenerate missing structures and to cure heart failure, diabetes, cancer, and neurodegeneration. The hype and controversy of human embryonic stem (ES) cells led the proponents of stem cell research to promise very rapid development of very radical cures. In reality progress will be slow. There are a number of lessons that we can learn from the development of haematopoietic stem cell transplantation (HSCT), which is one of the major applications of stem cell therapy in clinical practice.
“期望:现实与不现实”考虑了生物医学科学的目标,即再生缺失的结构,治愈心力衰竭、糖尿病、癌症和神经变性。人类胚胎干细胞(ES)的炒作和争议导致干细胞研究的支持者承诺非常迅速地发展非常彻底的治疗方法。实际上,进展将是缓慢的。造血干细胞移植(HSCT)是干细胞治疗在临床实践中的主要应用之一,我们可以从造血干细胞移植的发展中吸取许多教训。

4. Therapy using pluripotent stem cells 4. 多能干细胞治疗

‘Therapy using pluripotent stem cells’ examines some of the diseases that have been the first to be treated by cell therapy using pluripotent stem cells as the source material. Proposed cell therapies involve making the required differentiated cells in vitro and then implanting them into the appropriate site in the patient. The biggest success story so far is the treatment of the retina for a condition called age-related macular degeneration (ARMD). Diabetes is one of the top targets for cell therapy based on pluripotent stem cells, building on an existing form of cell therapy called islet transplantation.
“使用多能干细胞的治疗”探讨了一些首次使用多能干细胞作为来源材料的细胞疗法治疗的疾病。拟议的细胞疗法包括在体外制造所需的分化细胞,然后将它们植入患者的适当部位。迄今为止,最大的成功案例是治疗视网膜上的老年性黄斑变性(ARMD)。糖尿病是基于多能干细胞的细胞疗法的首要目标之一,这种疗法建立在一种叫做胰岛移植的现有细胞疗法的基础上。

‘Tissue-specific stem cells’ explores tissue-specific stem cells, which are stem cells found in the postnatal body that are responsible for tissue renewal or for repair following damage. Tissue-specific stem cells share with pluripotent stem cells the same ability to persist indefinitely as a population, to reproduce themselves, and to generate differentiated progeny cells. However, tissue-specific stem cells share few molecular characteristics with embryonic stem (ES) cells or induced pluripotent stem cells (iPS cells), such as expression of specific transcription factors or cell surface molecules. Only renewal tissues have stem cells in the sense of a special population of cells that reproduce themselves and continue to generate differentiated progeny.
“组织特异性干细胞”探索组织特异性干细胞,这是在出生后体内发现的负责组织更新或损伤后修复的干细胞。组织特异性干细胞与多能干细胞具有相同的能力,可以作为一个群体无限期地持续存在,自我繁殖,并产生分化的后代细胞。然而,组织特异性干细胞与胚胎干细胞(ES)细胞或诱导多能干细胞(iPS细胞)在表达特定转录因子或细胞表面分子等分子特征上几乎没有共同之处。只有更新组织才有干细胞,因为干细胞是一种特殊的细胞群,可以自我繁殖并继续产生分化的后代。
