项目摘要

The proportion of people around the world aged over 60 years is growing faster than any other age group, as a result of longer life expectancy. This population ageing can be seen as a success story for public health policies and for socioeconomic development, but it places a challenge on medicine and, within the UK, the NHS to maximize the health and functional capacity of older people. Regenerative Medicine is one potential solution for this longer life and healthy lifestyle, providing cell based therapies which can replace damaged or diseased tissues. Growing replacement tissues is bringing exciting novel solutions which now require new manufacturing methods and processes to enable the translation to the clinic. Bioreactors are mechanical devices that provide controlled growth environments for engineered tissues and mimic the physical forces cells and tissues experience in the body. Monitoring the maturation of tissue implants during culture, and prior to implantation into the patient, is important for defining optimum manufacturing criteria and for their clinical success. Key properties that tissue engineered implants must display include strength and durability. To infer material properties from imaging, new non-destructive, three-dimensional imaging techniques are needed, that can be used to provide accurate results efficiently at both the manufacturing site and the clinic. In this proposal, our partners have linked the imaging technique, optical coherence elastography, with a hydrostatic pressure bioreactor to create a novel imaging solution, MechAscan, which allows real-time mechanical characterisation and simultaneous physical stimulation of engineered tissue implants. MechAscan will provide a clear advantage over currently available traditional mechanical testing approaches and elastography techniques, which require direct contact of the mechanical load with the sample and are destructive. Additionally, MechAscan can be used for real-time monitoring of mechanical properties as the construct is grown in culture in a sterile growth environment. Our aim is to develop a novel technology platform allowing real-time and non-destructive monitoring of tissue engineered products in a sterile growth environment to avoid construct to construct variation during manufacturing and allow the translation of regenerative medicine constructs with known properties into the clinic. To facilitate uptake in use of the technology and translation to the clinic, we propose to fully test and validate the MechAscan technology in an interdisciplinary approach combining bioreactor technology, biomaterials science, physics and mathematics.

由于预期寿命延长，全世界60岁以上人口的比例增长速度超过任何其他年龄组。这种人口老龄化可以被视为公共卫生政策和社会经济发展的一个成功案例，但它对医学和英国的NHS提出了挑战，以最大限度地提高老年人的健康和功能能力。再生医学是这种长寿和健康生活方式的一种潜在解决方案，提供基于细胞的治疗方法，可以替代受损或患病的组织。生长替代组织带来了令人兴奋的新解决方案，现在需要新的制造方法和工艺才能将其转化为临床。生物反应器是为工程组织提供受控生长环境并模拟体内细胞和组织经历的物理力的机械装置。在培养期间和植入患者之前监测组织植入物的成熟对于定义最佳制造标准和其临床成功是重要的。组织工程植入物必须显示的关键特性包括强度和耐久性。为了从成像中推断材料特性，需要新的非破坏性三维成像技术，该技术可用于在制造现场和临床上有效地提供准确的结果。在这项提案中，我们的合作伙伴将光学相干弹性成像技术与静水压力生物反应器相结合，以创建一种新型的成像解决方案MechAscan，该解决方案允许对工程组织植入物进行实时机械表征和同步物理刺激。MechAscan将提供一个明显的优势，目前可用的传统机械测试方法和弹性成像技术，需要直接接触的机械负载与样品和破坏性。此外，MechAscan可用于实时监测结构在无菌生长环境中培养时的机械性能。我们的目标是开发一种新的技术平台，允许在无菌生长环境中对组织工程产品进行实时和非破坏性监测，以避免制造过程中的结构变化，并允许将具有已知特性的再生医学结构转化为临床。为了促进该技术的使用和临床应用，我们建议采用跨学科方法，结合生物反应器技术，生物材料科学，物理学和数学，全面测试和验证MechAscan技术。
