Regenerative Medicine of Articular Cartilage: Characterization and Comparison of Chondrogenic Potential and Immunomodulatory Adult Mesenchymal Stem Cells (ARTHROSTEM)

NCT01879046

  Purpose
Articular cartilage can be the seat of many diseases including osteoarthritis and traumatic defaults. The cartilage has no intrinsic ability to repair resulting at long term in function loss in the joints. Currently available treatments are not satisfactory in the long term, the use of mesenchymal stem cells appears to be promising due to their ability to multipotency and immunomodulation properties. This project aims to determine the most appropriate source for regenerative medicine of cartilage stem cells from tissue taken during arthroplasty in patients with osteoarthritis. These cells will be tested for different chondrogenic markers. The success of this project will consider the implementation of a strategy for regenerative medicine in bone and joint diseases.

Primary Outcome Measures:
  • Increased expression of chondrogenic markers [ Time Frame: up to 3 years ]

    Increased expression of chondrogenic markers will be Evaluated by different techniques:

    in vitro: Histology fit for chondrogenic markers, RT-PCR on the following markers aggrecan, type II collagen, Sox9, Comp, type IX collagen

    in vivo: In a second step, differentiated MSCs are implanted in vivo after combination with a hydrogel subcutaneously in nude mice. The formation of a neo cartilage tissue will be assessed by histology for type II collagen and aggrecan



Secondary Outcome Measures:
  • Increasing secretion of anti-inflammatory molecules in vitro [ Time Frame: up to 3 years ]

    Increasing secretion of anti-inflammatory molecules in vitro will be tested by several techniques:

    Microfluidic cards (TLDA assays) for the analysis of the expression of genes involved in inflammation and in the secretion of anti-inflammatory molecules Inhibition of proliferation of autologous T cells activated or not Assay for anti-inflammatory and pro-inflammatory molecules Analysis of the expression of surface markers by flow cytometry
