Abstract

Previous studies have reported that the conditioned medium (CM) of bone marrow-mesenchymal stem cells (BM-MSCs) stimulate the migration and proliferation of cell types involved in the wound healing process. However, these studies only show MSC-CM effects that were obtained using a two-dimensional (2D) culture. Recently, a three-dimensional (3D) culture has been considered to be a more physiologically appropriate system than the 2D culture. In addition, it has been shown that the procurement of BM-MSC is invasive, and other sources of MSC are thus being explored. Recently, perivascular cells (PVCs) have been considered as an alternative source of cells for dermal wound healing. Therefore, in this study, a PVC-conditioned medium (CM) was collected from a 3D culture (PVC-CM-3D) using highly porous polystyrene-based membranes and compared with PVC-CM from a 2D culture (PVC-CM-2D) to investigate the effects on the migration and proliferation of human keratinocytes and fibroblasts. Moreover, the PVC-CM components from the 2D and 3D cultures were identified using 2D gel electrophoresis. The migrations of the keratinocytes cells and fibroblasts were significantly higher with PVC-CM-3D than with the 2D culture; similarly, the proliferation of keratinocytes was also highly stimulated by PVC-CM-3D. Proteomic analyses of the PVC-CM revealed that type I collagen was highly expressed in the 3D-culture system. Microtubule-actin cross-linked factor 1 (KIAA0465), nebulin-related anchoring protein, and thioredoxin were specifically expressed only in PVC-CM-3D. In addition, more EVs could be isolated from the PVC-CM-3D, and EVs were found to stimulate keratinocyte migration. Taken together, 3D-culture using a polystyrene scaffold is demonstrated to be a better system for providing better physiological conditions; therefore, PVC-CM-3D could be a promising option for skin-wound healing.
