细胞培养法检测材料生物相容性是一种快速、简便、重复性好又价廉的方法，在材料生物相容性评价中起着越来越重要的作用。由于新材料不断涌现、材料植入体内的部位及使用目的日趋繁杂、材料毒性作用的强弱以及与机体反应的复杂性等因素决定了细胞毒性试验中实验方法及实验细胞的多样性。根据生物材料本身的理化特性、植入体内的部位及使用目的选择适当的实验方法和实验细胞至关重要。以往对材料生物相容性的评价往往着眼于细胞的形态与数量的变化，近几年来研究材料对细胞生长、附着、增殖及代谢方面影响的报道日趋增多，并提出了以有活力的细胞数和细胞生长作为材料生物相容性评价标准的观点。通过结合免疫 、化学、放射及影像学等多学科的技术发展，使人们进一步深入了解细胞结构和功能的变化关系，进而阐明材料对细胞的作用机制，是今后细胞培养法评价材料生物相容性的发展方向。
　　
　　　　Abstract It is quick convient good-repeating and cheap that examining the biotic materials compatibility through cell-culturing method,and it is more and more important in evaluating the compatibility of biotic material.The new material appeating continously complicating of the part and aim material be planted in the intensity of materials toxic effect the reactions complication of material and biotic body,all of these decide the variety of experiment method and cells in cell toxicity experiment.It is very important that choices the right experiment method and cells according to the materials character the part and aim the material be planted in .The evaluation of biotic materials compatibility stressed on the changing of cells form and quantity before.Inrecent years,more and more reports appear about material influeances the growth.adhesion proliferation and metabolizing of cell.and presents the point that the evaluation standard of biotic materials compatibility should be set according to the active cells quantity and their growth.Combining many subjects technological development,such as immunology, chemistry,radiation and shadowgraphy,thoroughly inquires the changeing relation of cells structure and funtion,furtherly clarifes the materials effect on cell,It is the developing direction in the future that evaluates the biotic materials compatibility in cedd-culturing method.

　　生物材料的临床应用已有较长的历史，广泛应用于牙科、眼科、整形外科及心血管外科领域。目前美每年有2-3百万人工脏器或假肢植入人体中。生物材料不仅要具有临床使用时所需要的理化性能，还必须具有良好的生物相容性，以保证使用安全。如何快速准确地评价材料的生物相容性，对于研制新材料和缩短研究周期起着重要的作用
