Sema3A promotes the cell proliferation ability of human alveolar bone marrow mesenchymal stem cells. (A) CCK-8 proliferation assay was conducted, and the OD was measured at 490 nm to determine the cell proliferation. (B) Clone formation assay results. The number of cell clones with >50 cells was counted under a microscope and the cloning efficiency was calculated. Tests were performed in triplicate, and data are represented as the mean ± standard deviation. Sema3A, semaphorin 3A; CCK-8, Cell Counting Kit-8; OD, optical density.
