Marrow Mesenchymal Stem Cells

Articular cartilage has poor repair capacity due to its avascular and aneural properties and has relatively few cells. This study investigated the ability of autologous implantation approach using three dimensional (3D) constructs engineered from bone marrow mesenchymal stem cells (BMSCs) seeded on poly(lactic-co-glycolic acid) (PLGA) with or without fibrin as cells carrier for the repair of osteochondral defect in rabbit model. The engineered 3D constructs – PLGA/Fibrin/BMSCs and PLGA/BMSCs – were cultured for 3 weeks in vitro and implanted autologously to the osteochondral defect created in the rabbit knee. The in vivo constructs were harvested and evaluated by means of gross observation, histology assessment, gene expression study, sulphated glycosaminoglycan (sGAG) production assay and biomechanical evaluation at 6 and 12 weeks post implantation. The results showed that the osteochondral defects treated with the PLGA/Fibrin/BMSCs constructs exhibited better repairment, more cartilaginous extracellular matrix, higher sGAG production, superior compressive strength and more intense expression of chondrogenic marker genes than the PLGA/BMSCs group. This study suggested that the PLGA/Fibrin/BMSCs has the potential to treat osteochondral defect and may be presented as a viable therapeutic option for those who would be in need from the life-extending benefits of tissue replacement or repair.

We developed a (three-dimensional) 3D scaffold, we named HY-FIB, incorporating a force-transmission band of braided hyaluronate embedded in a cell localizing fibrin hydrogel and poly-lactic-co-glycolic acid (PLGA) nanocarriers as transient components for growth factor controlled delivery. The tenogenic supporting capacity of HY-FIB on human-Bone Marrow Mesenchymal Stem Cells (hBM-MSCs) was explored under static conditions and under bioreactor-induced cyclic strain conditions. HY-FIB elasticity enabled to deliver a mean shear stress of 0.09 Pa for 4 h/day. Tendon and cytokine marker expression by hBM-MSCs were studied. Results: hBM-MSCs embedded in HY-FIB and subjected to mechanical stimulation, resulted in a typical tenogenic phenotype, as indicated by type 1 Collagen fiber immunofluorescence. RT-qPCR showed an increase of type 1 Collagen, scleraxis, and decorin gene expression (3-fold, 1600-fold, and 3-fold, respectively, at day 11) in dynamic conditions. Cells also showed pro-inflammatory (IL-6, TNF, IL-12A, IL-1β) and anti-inflammatory (IL-10, TGF-β1) cytokine gene expressions, with a significant increase of anti-inflammatory cytokines in dynamic conditions (IL-10 and TGF-β1 300-fold and 4-fold, respectively, at day 11). Mechanical signaling, conveyed by HY-FIB to hBM-MSCs, promoted tenogenic gene markers expression and a pro-repair cytokine balance. The results provide strong evidence in support of the HY-FIB system and its interaction with cells and its potential for use as a predictive in vitro model.
