Figure 2From: Good manufacturing practice-compliant isolation and culture of human umbilical cord blood-derived mesenchymal stem cells Timing of adherence and confluence of primary cultured cells. In 10% aPRP, MNCs adhered the soonest, and the adherence time gradually increased as the concentration of aPRP was decreased gradually (A). Consequently, the time needed to reach 70–80% confluence in 10% aPRP was the shortest, which gradually increased as the concentration of aPRP decreased gradually (B).Back to article page
