Objectives

Narrative objectives1

Among the various types of cells used in regenerative medicine, human mesenchymal stem cells have the ability to differentiate into bone, cartilage, and muscle, and their versatility has attracted considerable attention. Mesenchymal stem cells are isolated, cultured, and purified mainly from bone marrow. However, even at the research level, human iliac bone marrow fluid, the raw material for mesenchymal stem cells, is currently purchased from imported lumber products. Therefore, the most urgent issue to be solved is how to secure the raw materials for human mesenchymal stem cells in order to commercialize and industrialize them.
To establish a stable supply system for cell source materials, the ideal source would be the surplus specimens discarded or provided in large quantities during musculoskeletal surgeries, but detailed studies on which parts of the surgical surplus specimens should be collected and how much of them would be a sufficient cell source have not been conducted. However, detailed studies have not yet been conducted on which parts of the surgical surplus specimen should be collected, how much of it is sufficient, etc. Therefore, the purpose of this study is to extract and culture mesenchymal stem cells from perioperatively derived tissues and cells of scoliosis patients during musculoskeletal surgery, to confirm the quality of the obtained stem cells, and to evaluate their eligibility as a cell source by comparing them with conventional stem cells derived from iliac bone.

Assessment

Primary outcomes

1) Perioperatively derived cells obtained from scoliosis patients using cell surface antibodies such as CD73, CD90, CD105, and CD271 will be quantified for cellular components using flow cytometry.
2) The content ratio of the obtained mesenchymal stem cell markers and cell characteristics will be analyzed to see if they differ in each tissue to be harvested (e.g., thoracic spine, lumbar spine, iliac bone, etc.). In addition, cell surface antigens will be used as indicators for isolation, and cell functions will be evaluated by culture and transplantation experiments.

Key secondary outcomes

Evaluate gene expression (cell growth factor, bone-related genes, vascular endothelial cell growth factor, anti-inflammatory factor, etc.) and secreted factor components of mesenchymal stem cells isolated with various markers.
