Abstract:
:Bone marrow transplantation can lead to osteogenic repair of intractable bone conditions. To achieve optimal clinical results, it is necessary to transplant as many cells with osteogenetic potential as possible. However, approaches involving special equipment and reagents for the extraction and purification of cells are expensive, and the complicated procedures involved are a hindrance to widespread acceptance of bone marrow transplantation for osteogenic repair. To standardize bone marrow transplantation for bone regeneration, a simple, safe, clean, and low-cost system is required. We describe an easy-to-use method using a conventional manual blood bag centrifugation technique traditionally used for extracting buffy coats, for concentration of cells from bone marrow aspirates (BMAs) to obtain osteogenic progenitors.
