Topic 1 – Advanced Therapeutics for Bone and Cartilage Regeneration

Presentation

Regenerative medicine has burgeoned due to recent advances in stem cells and biomaterials to meet the goal of cell and organ replacement to restore function resulting from degeneration, aging, trauma, or other disease processes. The objective of our topic is to provide better clinical treatment to patients suffering from bone and cartilage diseases, using our knowledges and cutting-edge biotechnologies.

 

Bone defects can be caused by different origins, such as trauma, tumor or infection, and regeneration, filling and replacement are different strategies for bone repair according to the size of lesion. To avoid the total replacement of bone by prothesis, we have developed two different strategies according to patient’s need to either regenerate or fill bone lesions.

 

A therapeutic wound dressing technology to prevent early osteoarthritis following traumatic knee injuries

Osteoarthritis (OA) is one of the most widespread chronic diseases in adults. By 2030, about 20% of adult people will be affected by OA in industrialized countries. About 6 million people in France suffer from OA. Knee injury is one of the strongest risk factors for OA. Today, the main techniques involved in OA lesions repair present important constraints with limited efficiency or side effects, such as fibrocartilage formation, hypertrophic or hypotrophic cellular content with subsequent degeneration, and inadequate linking to the host bone/cartilage. The need for more efficient therapies is tremendous. In this context, our objective is to regenerate the cartilage in a more stable way through the regeneration of the subchondral bone, acting as glue between bone and cartilage.

 

Design and Optimization of a Combined Therapeutic Implant based on Stem Cells Spheroids for Meniscal Repair

The menisci are two crescent-shaped fibrocartilaginous structures in the knee, playing an important protective role for the knee joint through shock absorption, load distribution and joint lubrication due to their deformable shape and mobile nature. Unfortunately, the meniscal injuries are quite common with a 61 per 100,000 incidence rate of meniscal tears in the general population. Owing to the hypovascular and hypocellular properties, meniscus tears could not heal spontaneously, thus, leading to knee OA. We propose an innovative 3D bioengineering Cyfuse S-PIKE technology combined with mesenchymal stem cells (MSCs) to regenerate and replace the meniscus with better safety and accuracy.

 

Patient-derived vascularized minitissue based microfluidic drug screening device

Osteosarcoma is the most common primary bone malignancy presenting typically during childhood and adolescence. However, few improvements of the survival outcomes for osteosarcoma patients have been achieved since the last three decades. Despite the rarity of the diagnosis, the complexity of tumour microenvironment and the genetic heterogeneity remain the major obstacles to understanding the mechanisms involved in the tumour progression and metastasis, and to screening the pharmacologically active molecules for better drugs. In this context, our objective is to develop an innovative drug-screening device which combines the patient-derived vascularized tumour or healthy minitissue with a perfusable microfluidic network to test therapeutic molecules and provide a rapid and personalized clinical treatment to the patient.
