Following the publication of this article [1] the authors informed us of the following errors:

1. Figure 18 should be removed, since this is the same as Fig. 16.

2. Figure 17 legend should be replaced by Fig. 18 legend to read:

   Fig. 17 Patient-Specific Platelet-Rich Plasma (PRP) bioink using 3D bioprinting of alginate scaffold a Schematic of PRP extraction and its incorporation with alginate to form patient-specific bioink b Schematic of proposed bioprinting process c PRP incorporated alginate scaffold containing fluorescence particles. d Images of different PRP-alginate constructs. In the production of these constructs 0.04% (w/v) CaCl2, 50 U ml − 1 PRP, and 1% (w/v) alginate was used. e, f The fabricated constructs could easily be removed from the substrate without losing their integrity. g Metabolic activity of mesenchymal stem cells (MSCs) treated with alginate and alginate/PRP over 5 days without any growth factor. h Metabolic activity of human umbilical vein endothelial cells (HUVECs) treated with alginate and alginate/PRP over 3 days without any growth factor.
