Evaluation of biological therapies and diagnostic targets for the degenerative intervertebral disc (Theranostic)

Background

Intervertebral disc (IVD) degeneration is a major factor contributing to the development of back and neck pain, which represents a global burden for patients, clinicians, and the society. For patients with early signs and symptoms who are not responsive to conservative treatment but do not yet qualify for spine surgery, therapeutic options are scarce. Recently, intradiscal injection of mesenchymal stromal cells (MSCs) derived from bone marrow has shown promising outcome in patients suffering from discogenic low back pain. The therapeutic effect of locally delivered MSCs has been attributed to their secretion of immune-modulatory, anti-inflammatory, and regenerative mediators. Direct application of MSC secretome is therefore an attractive therapeutic approach, avoiding some of the hurdles and risks of cell injection. 

 

 

Goal

One aim of this project is to evaluate the potential of MSC secretome for IVD regeneration using cell and organ culture models. First, the secretome of human MSCs stimulated with different human IVD conditioned media will be characterized to assess the MSCs response to the IVD environment. Secondly, the therapeutic effect of stimulated MSCs' secretome on IVD cells and tissues will be investigated. Composition of the secretome will be correlated to its regenerative effect to identify potent secretomes for further pre-clinical study.
