Kinetics of human CD34+ cell expression in the 3D induction systems during the differentiation for 0–10 days. The results showed that CD34⁺ cells were routinely detected in 3D induction systems, and its expression was kinetic states. From the initial induction, the percentage was low, and then began to increase. At about day 7, the peak was about 90 %, and then began to decrease. In all 3D induction cultures, peptide scaffolds fused with OP9DL1, BM plus sets of factors held better capacity to produce CD34⁺ cells during the induction phase. Data were shown as mean ± SEM, n = 3–6
