Corrigendum to “Chemical group-dependent plasma polymerisation preferentially directs adipose stem cell differentiation towards osteogenic or chondrogenic lineages”

The authors regret to report that errors were published in this manuscript: the representative image of the COOH group in Figure 3C is not correct, the representative image of the POSS-PCU group in Figure 9A and 9D are not correct, and the representative image of the NH2 group in Figure 9E is not correct. These images were wrongly named and as a result the wrong image was unintentionally included. Full corrected figures are provided here along with their original figure captions. These updates do not change the description, interpretation or the original conclusion of the article. The authors apologize for any inconvenience caused.

Adhesion of adipose-derived stem cells (ADSCs) on plasma modified scaffolds 24 h after seeding. A) Expression of focal adhesion kinase (FAK) and vinculin assessed by RT-qPCR. Note greater expression of these transcripts on the COOH modified scaffolds (p < 0.05). B) Double staining for vinculin (green) and actin (red); note expression of vinculin in all scaffolds. Nuclei are stained with Dapi (blue). Scale bar: 20 um. C Scanning electron microscopy images of ADSCs on the different scaffolds; the arrows point to ADSCs spread on the scaffolds Scale bar: 30 um.

Chorioallantoic membrane (CAM) grafting of adipose-derived stem cells (ADSCs) on plasma modified scaffolds for 7 days. A-C) Images of CAM-grafted scaffolds in vivo and D-F) after removal from the CAM. G-I). Scaffold sections stained with hematoxylin and eosin. Dotted lines indicate the edge of the scaffold material. Scale bar: 500 um. J-L) Detection of laminin (green, J-L) and vascular endothelial growth factor (VEGF) (red, M-O) and by immunocytochemistry in scaffold sections. Staining levels in POSS-PCU scaffolds appear to be lower than in NH2 and COOH scaffolds. Scale bar: 200 um.
