Overview

abstract

  • PURPOSE: To assess the response of bone marrow-derived mesenchymal stromal cells (bMSCs) enhanced by platelet-rich plasma (PRP) in the setting of a normal human tendon (NHT), a demineralized bone matrix (DBM), and a fibrin scaffold (FS) with simulated arthroscopic mechanical washout stress. METHODS: Bone marrow was aspirated from the humeral head and concentrated. BMSCs were counted, plated, and grown to confluence. Cells were seeded onto 3 different scaffolds: (1) NHT, (2) DBM, and (3) FS. Each scaffold was treated with a combination of (+)/(-) PRP and (+)/(-) arthroscopic washout simulation. A period of 60 minutes was allotted before arthroscopic washout. Adhesion, proliferation, and differentiation assays were performed to assess cellular activity in each condition. RESULTS: Significant differences were seen in mesenchymal stromal cell adhesion, proliferation, and differentiation among the scaffolds. DBM and FS showed superior results to NHT for cell adhesion, proliferation, and differentiation. PRP significantly enhanced cellular adhesion, proliferation, and differentiation. Arthroscopic simulation did not significantly decrease bMSC adhesion. CONCLUSIONS: We found that the type of scaffold impacts bMSCs' behavior. Both scaffolds (DBM and FS) were superior to NHT. The use of an arthroscopic simulator did not significantly decrease the adhesion of bMSCs to the scaffolds nor did it decrease their biologic differentiation potential. In addition, PRP enhanced cellular adhesion, proliferation, and differentiation. CLINICAL RELEVANCE: Improved healing after tendon repair can lead to better clinical outcomes. BMSCs are attractive for enhancing healing given their accessibility and regenerative potential. Application of bMSCs using scaffolds as cell carriers relies on arthroscopic feasibility.
