ABSTRACT
BACKGROUND:
Human bone marrow cells-derived extracellular matrix can promote proliferation of human periodontal ligament stem cells and maintain stem cellproperties.OBJECTIVE:
To preliminarily investigate the effect of human bone marrow cells-derived extracellular matrix on the proliferation of human periodontal ligament stem cells.METHODS:
Human periodontal ligament stem cells and bone marrow cells were separately derived from human periodontal tissue and jaw bone marrow, and human bone marrow cells-derived extracellular matrix was prepared. Human periodontal ligament stem cells were cultured and purified using limited dilution cloning method, and transmission electron microscope was used for ultrastructure observation. Human periodontal ligament stem cells at passage 2 were cultured with human bone marrow cells-derived extracellular matrix and normal culture medium (control group). The cellcounting kit-8 and flow cytometry were used to determine the proliferation potential of human periodontal ligament stem cells cultured on human bone marrow cells-derived extracellular matrix. RESULTS ANDCONCLUSION:
Compared with the control group, human periodontal ligament stem cells cultured on human bone marrow cells-derived extracellular matrix had a superior capacity of proliferation (P<0.05), and the cells met their morphological and biological characteristics, and grew in good conditions. Human bone marrow cells-derived extracellular matrix is a promising matrix for large-scale expanding human periodontal ligament stem cells for future use in stem cel-based therapy.
