Organized by ORS Preclinical Models Section

Many investigators do them or will do them: preclinical studies. Most researchers will learn how to conduct them “on the job”. However, students and trainees may be overwhelmed with all things to know and think about. A basic understanding of preclinical model design and execution is essential for young investigators.

With these ideas in mind, the ORS Preclinical Models Section is excited to offer a NEW half day workshop for investigators at all career stages. The workshop will benefit anyone currently in the field or entering the field of preclinical studies. We aim to teach the basics and some of the tools needed to conduct preclinical research. Beside lectures, questions and discussions will be an integral part of this workshop. All attendees will be encouraged to submit questions or examples to be incorporated into the workshop.

Each session will be 1 hour long with breaks included .

OA on a compressed timeline. There is emerging interest in compression models of OA that can non-invasively induce joint degeneration in mice and rats using externally-applied mechanical loads to injure the ACL or overload the articular cartilage. These models can be implemented using a variety of methods, and each method has its own advantages, limitations, and technical considerations. The purpose of this workshop is to discuss the development and implementation of compression models of OA, and present common hurdles encountered when using these methods. The three presenters each have considerable expertise with different compression models, giving them unique perspectives on the use of these models in their research. The goal of this workshop is to utilize this experience to provide insight to investigators who are using or are interested in using compression models of OA.

The goal of this session is to understand the application of formal lab quality systems such as ISO 17025 or Good Laboratory Practices and explore how aspects of these systems can be applied to academic labs for studies that support regulatory filings and translational research. Speakers will present an overview of their implementation of lab quality system structures and discuss how they have applied aspects of these systems to their labs to improve productivity, training, data integrity and support translational research. The session seeks to bring together aspects of academia, industry and regulatory requirements to identify best practices towards optimizing scientific studies and achieving approval for human clinical studies.

In healthy individuals, lean muscle accounts for 38 – 54% and 28 – 39% of total body mass, in men and women, respectively. These ranges are quite broad and are dependent upon multiple factors including age, physical activity level, overall health, genetic makeup, and nutritional input. Losses of muscle mass or functionality, whether a consequence of genetic or systemic disease, aging, trauma, or surgical intervention, is a major contributor to impaired mobility and a diminished quality of life. Understanding the genetic factors influencing muscle development and functionality are areas of intense basic biomedical research. This workshop will introduce recent advances in our understanding of muscle biology, including the genetic basis of muscular disease and the molecular regulation of muscle gene expression. Efforts to identify the underlying molecular programs responsible for the progression of muscle disease, as well as targeted molecular interventions, will be discussed.

Wearable and soon even implantable sensors allow the permanent, unobtrusive and objective assessment of patients to a) digitally transform outcome measurement in clinical trials, b) generate novel, “digital biomarkers” for diagnostics or predictive and preventive screening, and c) to empower patients by feedback and coaching advise in a patient-centric and personalized way. This is particularly relevant in orthopaedics where movement and physical activity behaviour is directly affected by disease and treatment and can now be monitored with body-worn sensors.

There have been several issues raised in the last two decades concerning our current and historically utilized biomaterials in orthopaedics. There is a current need to bring these issues to light so that they can be investigated and solved to further advance the treatments and outcomes for patients. Although we have utilized current biomaterials in orthopaedic surgery for decades there have been several issues raised in the recent past that may be limiting the outcomes of patients. We aim to bring these issues to light in a debate type format to give the attendees a look into the future where issues like corrosion, biofilm formation, and hypersensitivity are no longer a concern in orthopaedics. To advance the education of attendees we will create a town hall discussion format after each side of a topic is presented to advance research in biomaterial science.

The research field osteoimmunology has revealed a striking and essential interdependency between bone and immune cells. The possibility of immune modulatory therapeutic approaches has gained interest. However, the sheer diversity and inherent plasticity of immune cells present during the bone healing process accounts for numerous unresolved aspects that are under current research observation. Inflammation is needed to initiate healing, but has to be strictly regulated to stay on the “good” side of the healing influences. In elderly, the ratio of M1:M2 macrophages is skewed and this dysregulation could be responsible for healing problems. CD8 effector T cells negatively influence bone healing, while regulatory T cells enhance healing. Their ratio could be a biomarker for predicting delayed healing. An in depth understanding of the interdependency of the immune and skeletal system can serve as a basis for the development of future immune modulatory treatment strategies.

The ability to analyze individual cells within a tissue or cell population is transforming biology and medicine by allowing for the identification of new cell types and lineages that are present during normal and disease states. This workshop will feature speakers who are using cutting edge technologies to study the epigenome, transcriptome and/or proteome of musculoskeletal tissues at the single cell level. Speakers will review the strengths and limitations of current single cell technologies (scRNA-seq, Cy-ToF, and sci-ATAC-seq) as compared to bulk technologies and summarize how these technologies are advancing our understanding of skeletal development and disease.

Intervertebral disc (IVD) degeneration is a common cause of back pain. IVD begins early in adult life and may progress slowly for decades until becoming symptomatic and requiring medical intervention. The adult human IVD seems incapable of intrinsic repair and there are currently no proven treatments to prevent, stop or even retard disc degeneration. Fusion is currently the most common surgical treatment of symptomatic disc disease. However, radiographic follow-up studies have revealed that as many as 80% of patients may develop adjacent segment disc degeneration due to altered spine biomechanics. A biological means to treat disc degeneration is therefore desirable. The purpose of the workshop is to look at recent advances and future prospects of disc repair.

Clinical symptoms of OA appear in more than 10% of the world population and affect almost everyone over the age of 65. As a consequence of the increasing longevity and obesity within the western countries, the economic and social burden caused by OA is growing rapidly and substantially influencing the life quality of the affected individuals with enormous costs to the health care system for diagnosis, treatment, sick leave, rehabilitation, and early retirement. For the patients the major problem is disability, resulting from joint tissue destruction and pain. Here, we want to elucidate novel concepts and hypotheses regarding disease progression, which are relevant for understanding underlying molecular mechanisms as a prerequisite for future therapeutic approaches.
