- Biology, assessment and maintenance of skeletal health - MED6510
Module Co-ordinator – Enrico Dall'Ara
The aim of the module is to make the students familiar with the structure and cellular composition of bone and with the process of bone formation and resorption. This will constitute the basis on which the students will build more specialised and cutting edge knowledge on control of bone homeostasis or loss of it with age. The students will then use this knowledge to be able to propose the correct experimental procedures to assess skeletal health in humans and experimental models and to critically evaluate interventions to prevent or delay skeletal ageing.
The module will primarily involve private study with the material provided online. In addition students will be expected to perform their own search for information and identify key research papers to gain experience of analysing experimental work, data presentation and discussion and interpretation of results.
At the end of the module the student will have:
• Developed a systematic understanding and in depth knowledge in the following 5 areas:
• Bone structure and mechanical properties of bone
• Processes of endochondral and intramembranous bone formation
• Bone remodelling and the effects of age and disease
• Experimental models and methods of assessment of skeletal health
• Pharmacological and lifestyle intervention to skeletal health in the ageing population
• Have a conceptual understanding of the above 5 areas that enables them to critically
• Evaluate current research and methodologies and develop critiques of them.
The module will be delivered online and self-directed learning with independent study time. It also includes video lectures, screencasts, links with published papers and reports, MCQ style formative assessments, reflective journals, live lectures and live discussions of case studies.

The Research Project in Sheffield
Module code: MED6511
In the second semester (approx. February - August), you will undertake a 120 credit research project. You will be asked to choose from a selection of pre-existing projects (for examples of projects that have been on offer in previous years, see download box on the right), or you are welcome to propose your own to suit your future career plans (subject to Training Committee approval).
You will be supervised by CIMA researchers based across all 3 of the CIMA sites, giving you a truly collaborative and multi-disciplinary supervisory team. You will also partake in up to 3 weeks of placements at any of the other CIMA sites to give you the chance to liaise with your supervisors and fellow students at other institutions, to use their facilities and laboratories, or perhaps to learn a new technique.
As part of the research project module, you will undertake up to 3 weeks of exchange visits to either (or both) of the two CIMA sites (Liverpool and Newcastle), so that you can access facilities and resources relevant for your project.
Exchange visits are an integral part of the MRes because although individually each University has excellent facilities for basic science research, pre-clinical and clinical research, as a student of CIMA, you will have shared access to high-end technology and expertise, access to model systems that cover the musculoskeletal system as a whole and clinical expertise and resources not available in any single institute.
To ensure you develop an optimal range of complementary skills and are prepared to make an informed choice about future career directions, during the research project, you will prepare a training needs analysis and a personal development plan with the help of your supervisors and tutor. This will contain approximately 200 hours worth of activities among those offered by the University of Sheffield and within CIMA. You will be required to keep a log of all your activities using the e-portfolio.
Assessment for the module includes the following components:
- 7500 word project dissertation - worth 70%
- Oral presentation - worth 10%
- E-portfolio and lab book - worth 20%
It will give you practical experience in:
- Planning research
- Critically evaluating data from your work and others
- Laboratory experimentation and record keeping
- Training in writing a substantial scientific document

Previous research projects
Here are a few examples of research projects already completed at Sheffield as part of the MRes in Musculoskeletal Ageing. Remember, we encourage students to propose their own projects if they have any ideas of their own that would particularly fit with their future career plans and we will be happy to discuss this with students once they start the course.
- Combining mechanical loading and anabolic therapy in postmenopausal women – a pilot study
The effects of mechanical loading of the skeleton are age-dependent in both animal and human models (Skerry 1997; Skerry 2008). Improvements in bone geometry and strength can be induced by loading in childhood, whereas loading in older adults seems to predominantly preserve bone mass and structure with modest, if any, improvements in site-specific geometry and mass(Hamilton, Swan et al. 2010). Several anabolic therapies, e.g. teriparatide, improve bone mass and structure (Boonen, Marin et al. 2008; Glover, Eastell et al. 2009) and have shown synergy with loading in animal models (Li, Duncan et al. 2003; Sugiyama, Saxon et al. 2008). PTH can also influence blood flow, but little is known about the effect of combined therapy on muscle. Furthermore, it is not clear if results from animal models are transferable to humans. A potential interplay between loading (whole body vibration, WBV) and low dose anabolic therapy (teriparatide) could therefore lead to enhanced but cheaper combination therapies.
Aims and objectives:
This project aims to establish the impact of a 48 week intervention with low dose teriparatide on bone and muscle tissues in loaded and unloaded lower legs within the same subject. Power calculations suggest that a total of 20 subjects will be sufficient.
To reach this aim, we will:
Investigate the impact of medium-intensity unilateral mechanical vibration on a) cortical and trabecular bone parameters assessed by Xtreme CT in the distal tibia, b) spine and hip BMD (also QCT to be considered), muscle cross-sectional area (CSA) and c) muscle strength.
In a subgroup, we will explore the impact of teriparatide, with and without WBV, on markers of muscle protein synthesis and degradation, markers of muscle inflammation and evidence of modified Reactive Oxygen Species generation (including antioxidant defence protein and Heat Shock Protein content) and evidence of altered mitochondrial protein expression and activities. Muscle biopsies will also be examined for muscle fibre size.
Hypothesis: There will be no difference in bone and muscle mass or function between the loaded and unloaded lower leg in older women receiving low dose anabolic therapy.
- The effect of age and body weight on vitamin D metabolism
Vitamin D is a major determinant of the musculoskeletal phenotype. Knowledge gaps in the handling, storage, utilization and clearance of vitamin D metabolites have hampered progress in obtaining consistency in vitamin D intervention studies for improving musculoskeletal health outcomes in ageing.
Aims and objectives:
We aim to assess the significance of the observation of low vitamin D in obesity and with ageing by conducting detailed measurements of bone health.
To reach this aim, our proposal will take advantage of existing stored samples and data from current ongoing case-control studies of obese and lean children and adults of a wide age range (Study 1).
- Explore whether serum 25(OH)D is an appropriate biomarker of metabolic effect.
- Investigate how vitamin D and its metabolites are handled in the body.
- Assess how these processes vary according to body composition and life stage.
- Elucidate the mechanisms for the observation of low 25(OH)D in obesity and ageing.
We will consider the following hypotheses to explain this observation:
1. Low 25(OH)D results from low dietary vitamin D intake or low ultraviolet light (sunlight) exposure.
2. Low 25(OH)D results from increased requirement due to changes in pool size. The consequences of low 25(OH)D would be increases in PTH, and decreases in 1,25(OH)2D and calcium absorption, with no difference in metabolic clearance rate.
3. Low 25(OH) results from increased requirement due to increased metabolic clearance.
- An examination using murine models of the epigenetic changes that occur with age in bone marrow mesenchymal stem cells
In the musculoskeletal system mesenchymal stem cells (MSCs) are the common progenitors to cartilage and bone. In contrast, muscle progenitor cells reside in a different cell population, called satellite cells. Both types of stem cell are responsible for the maintenance and repair of the musculoskeletal system. Our group (IB) and others have shown that these cells undergo a process of cellular ageing (1-2), with a loss of proliferative and differentiation capacity that impacts detrimentally on tissue repair. Much like DNA polymorphism, epigenetic changes to chromatin can contribute to the ageing process. Unlike DNA polymorphism, these epigenetic changes are however plastic in nature and reversible. Epigenetic changes have been demonstrated in a number of stem cells, including MSCs aged in culture.
Aims and objectives:
For this studentship we will initially focus on epigenetic changes in MSCs in murine models. We will then compare the changes identified with epigenetic changes in satellite cells by collaborating with Prof. Tom Rando at Stanford University, who is running a parallel study in satellite cells.
To reach this aim, we will:
Validate the NestinGFP+ as bona fide MSCs.
Determine the changes in number and properties of NestinGFP+ MSCs with age.
Optimise the technology to determine epigenetic changes with a small number of cells.
Determine the epigenetic changes in NestinGFP+ MSC with age.
Our overall hypothesis is that there are common epigenetic changes in the musculoskeletal stem cells occurring with age in vivo and that maintenance of the chromatin epigenetic state by pharmacological intervention will lead to sustained retention of stem cell properties and tissue homeostasis.
- Analysis of the upper body movements during gait for the assessment of locomotor ability
Age and certain neurodegenerative diseases reduce an individual’s ability to walk safely and efficiently. Consequently, gait observation and quantification is potentially a powerful tool to identify incipient pathology, contribute towards diagnostic algorithms, and quantify intervention efficiency (lord, 2013). An emerging perspective is that the movement of upper body during gait plays a critical role in successful locomotion and may provide useful information for the elderly/pathologies due to it’s relation to critical aspects of walking, such as maintenance of balance, reduction of tissue mechanical loads, and energy efficiency. Healthy individuals adopt a ‘‘head stabilization in space’’ strategy during walking. This strategy, quantified by a reduction of body segment accelerations going from pelvis to head level, is already in place in pre-pubertal age (Mazzà, 2010), and is compromised in elderly women (Mazzà, 2008). Furthermore the control of the upper body has been found to be impaired as a result of age related neurodegenerative disease such as Parkinson’s disease (Cole, 2010). As a result, Upper body variables are proposed to be able to objectively quantify gait and balance decline as a result of ageing or for diseases whereby postural control is affected. Being the lower limb movements transmitted to the upper body through the pelvis, upper body movements can also be informative of gait variability (defined as stride-to-stride fluctuations of gait parameters), which is sensitive to change due to aging, intervention, and pathology (Lord 2012), the combination of the two may be increasingly informative. However, the lack of standardized testing protocols and knowledge of reliability of gait variability measurements still limits the interpretability of this data (Galna 2013, Lord 2011).
Aims and objectives:
With this project, we aim at:
- Establishing a lifespan reference metrics for the assessment of the head stabilization strategy and gait variability through devising experimental methods and data analysis techniques based on the use of wearable inertial sensors.
- Providing reference data and measurement procedures for the clinical assessment of life-style based intervention aiming at improving locomotor function and reducing falls for the elderly. Comparisons will be made from this reference data to determine if pathological elderly groups (e.g. arthritis, Parkinson’s disease) can be identified from their respective age matched controls.
- The role of gastrointestinal hormones and identification of GI hormone receptor expressions in bone cells
Human body has remarkable ability to adapt to different dietary requirements. Coordinated regulatory nervous and hormonal systems control human metabolism, ensure adequate response to various dietary, physiological situations and the appropriate flux through specific metabolic pathways (Frayn, 2010).
There are complex interactions between gastrointestinal (GI) hormones that regulate energy metabolism and bone homeostasis. These interactions are mediated directly through various calciotropic, gut and pancreatic hormones and peptides or indirectly via the endocrine organs (Talbott et al., 1998; Zeni et al., 2003, Naot and Cornish, 2008). Assessment of biochemical markers of bone formation and resorption suggest strong interlinks between food intake and bone remodeling. Abnormal dietary intake including anorexia of ageing, starvation and anorexia nervosa, and disorders of GI absorption including inflammatory bowel and celiac diseases may increase the risk of bone fractures and cause bone disorders (Bernstein and Leslie, 2003; Moss et al., 2011). These suggest that sufficient nutrient intake and normal GI function are essential for the skeletal health.
Aims and objectives:
The aims of this project were to analyse the expression of GI hormone receptors in two osteoblastic cell lines (SaOS-2 and Te85), stages of osteoblastic development and changes in GI hormon concentrations of fed or overnight fasted C57BL/6 mice.
To achieve the aims we have
- Assessed mRNA expression of GI hormone receptors in two osteoblastic cell lines using end-point PCR
- Performed mineralisation assay to study different stages of osteoblast development
- Measured the concentrations of insulin and glucagon hormones of fed (n=8) and overnight fasted (n=8) C57BL/6 mice using multiplex metabolic assay
The concentrations of metabolic hormones that have potent regulatory effects on bone formation differ during fasting and fed states. The functional activity of osteoblasts varies depending on developmental stages of osteoblast lineage. Identification of GI hormone receptor expressions in osteoblastic cell lines broadens our understanding of synergies between direct and indirect interactions of GI hormones and bone cells.
