<p>(A) BM MNCs from Balb/c mice following treatment with central marrow ECs, PlGF knockdown central marrow ECs, central marrow SCs or PBS were evaluated for LT-HSC, ST-HSC and HPC frequencies using flow cytometry (**p<0.01; n = 9 from 3 independent experiments; error bars represent standard deviation). (B) BM MNCs from the same mice were assessed for CAFC frequencies at weeks 2 and 5 (*p<0.05; n = 9 from 3 independent experiments; error bars represent standard deviation).</p
