Abstract
The periosteum covering the outer surface of bone contains skeletal stem/progenitor cells that can efficiently form cartilage and bone during bone repair. Several methods have been described to isolate periosteal cells based on bone scraping and/or enzymatic digestion. Here, we describe an explant culture method to isolate periosteum-derived stem/progenitor cells for subsequent in vitro and in vivo analyses. Periosteal cells (PCs) isolated using this protocol express mesenchymal markers, can be expanded in vitro, and exhibit high regenerative potential after in vivo transplantation at a fracture site, suggesting that this protocol can be employed for PC production to use in new cell-based therapies.
Keywords: Periosteum (骨膜)Background
Bone regeneration is a highly efficient process. After bone fracture, skeletal stem/progenitor cells are activated and differentiate into chondrocytes and osteoblasts that form cartilage and bone to consolidate the fracture. Skeletal stem/progenitor cells originate from the bone itself including bone-marrow and periosteum, as well as from adjacent soft tissue. The diverse origins of skeletal stem/progenitor cells during bone regeneration suggest that these cells can be obtained from various sources for stem cell therapies. Due to their accessibility, bone marrow stromal cells (BMSCs) are the most studied (Arthur and Gronthos, 2020); however, their variable osteogenic potential highlights the need for new sources of cells capable of contributing efficiently to the repair process. Recent studies have revealed the role of the periosteum as an essential source of stem/progenitor cells during bone regeneration (Debnath et al., 2018; Duchamp de Lageneste et al., 2018; Ortinau et al., 2019). When transplanted to a bone fracture site, periosteal cells (PCs) display a higher regenerative potential than BMSCs and have the ability to correct a bone repair failure (Duchamp de Lageneste et al., 2018; Julien et al., 2020). Isolating mouse PCs is challenging since the periosteum is a very thin layer of tissue on the outer surface of bone. Several methods have been previously described to isolate PCs in mice, relying on enzymatic digestion and periosteum scraping or peeling (Brownlow et al., 2000; Arnsdorf et al., 2009; Wang et al., 2010; Chang and Knothe Tate, 2012; van Gastel et al., 2012). Here, we describe a method to isolate PCs based on cell migration from bone explants without digestion or periosteum separation from the bone (Figure 1). We developed this method to analyze PC properties for direct comparison with BMSCs that are usually isolated by direct bone marrow flushing and plating. Long bones free of skeletal muscle, epiphyses, and bone-marrow are placed in culture to allow PC migration and proliferation. PCs isolated using this protocol express mesenchymal markers (Figure 2), display in vitro adipogenic, osteogenic, and chondrogenic differentiation capacities (Figure 3), and are able to form cartilage and bone upon in vivo transplantation at the site of a tibial fracture (Figure 4). PCs therefore maintain their osteochondrogenic capacities, offering new potential perspectives for the study of PCs and their use in cell-based therapies.
