Abstract: Platelet products (PP) and bone-marrow aspirate are popular sources of osteoinductive signalling molecules and osteogenic bone marrow mesenchymal stromal cells (BM-MSCs) used in the treatment of impaired bone healing. However, the combined use of PP and BM-MSCs in clinical studies has reported mixed results. Understanding the cellular and molecular interactions between PP and BM-MSCs plays the important role of guiding future research and clinical application. This systematic review investigates the effects of PP on the biophysiological functions of BM-MSCs in in vitro human studies, including (i) proliferation, (ii) migration, (iii) differentiation, (iv) growth factor/cytokine/protein expression, (v) immunomodulation, (vi) chemotactic effect on haematopoietic stem cells, (vii) response to apoptotic stress, and (viii) gene expression. In vitro studies in human have demonstrated the multi-faceted ‘priming effect’ of PP on the biophysiological functions of BM-MSCs. PP has been shown to improve proliferation, migration, osteogenic differentiation, reaction to apoptotic stress as well as immunomodulatory, pro-angiogenic and pro-inflammatory capacities of BM-MSCs. Several factors are highlighted that restrict the transferability of these findings into clinical practice. Therefore, more collaborative in vitro research in humans modelled to reflect clinical practice is required to better understand the effects of PP exposure on the biophysiological function(s) of BM-MSCs in human. |
