骨组织工程的一个目标是开发基于人类细胞的体外三维骨模型来研究骨生理和病理。由于患者细胞的异质性,理想情况下,需要从单个细胞来源获得患者自身的细胞。这篇综述试图确定适当的细胞来源发展这样的模型。骨髓和外周血被认为是提取成骨细胞/骨细胞和破骨细胞祖细胞的合适来源。最近对这些细胞来源的研究表明,分离的祖细胞之间没有显著差异。然而,培养基成分等多种参数会影响细胞的增殖和分化潜能,这可能使外周血源性干细胞优于骨髓源性干细胞。外周血可以被认为是成骨细胞/骨细胞和破骨细胞祖细胞的合适来源,对患者的侵袭性较小。然而,需要更多的研究集中于从同一供者外周血样本中提取和分化两种细胞。
One aim in bone tissue engineering is to develop human cell-based, 3D in vitro bone models to study bone physiology and pathology. Due to the heterogeneity of cells among patients, patient’s own cells are needed to be obtained, ideally, from one single cell source. This review attempts to identify the appropriate cell sources for development of such models. Bone marrow and peripheral blood are considered as suitable sources for extraction of osteoblast/osteocyte and osteoclast progenitor cells. Recent studies on these cell sources have shown no significant differences between isolated progenitor cells. However, various parameters such as medium composition affect the cell’s proliferation and differentiation potential which could make the peripheral blood-derived stem cells superior to the ones from bone marrow. Peripheral blood can be considered a suitable source for osteoblast/osteocyte and osteoclast progenitor cells, being less invasive for the patient. However, more investigations are needed focusing on extraction and differentiation of both cell types from the same donor sample of peripheral blood.
