摘要: The expansion of umbilical cord blood mononuclear cells (UCB MNCs) was investigated in a novel co-culture system by means encapsulation rabbit bone marrow (BM) mesenchymal stem (MSCs) alginate beads (Alg beads). Three kinds media were applied and the experiments lasted for 7 days. total nucleated cell density measured every 24 h. Flow cytometric assay CD34+ methylcellulose colony assays carried out at 0, 72 168 It found that encapsulated MSCs illustrated remarkable effects on UCB MNCs regardless whether serum is present culture or not. At end h co-culture, number multiplied 15 ± 2.9 times, 5.3 0.3 times colony-forming units (CFU-Cs) 5.6 1.2 serum-free supplemented with conventional dose cytokines, which very similar to results containing 20% media. While control, i.e. MNC without encapsula...
