Antibody increases podia formation from human bone marrow CD34⁺ cells. (A) CD34⁺ cells were cultured in methylcellulose agar with antibodies (50 μg/mL) or PBS for 6 d. Morphologies of cells were analyzed by bright-field microscopy. (B) CD34⁺ cells grown in methylcellulose agar were analyzed by SEM. The arrows indicate podia of CD34⁺ cells.
