Abstract
Correction for ‘Effect of hydrogel material composition on hBMSC differentiation into zone-specific neo-cartilage: engineering human articular cartilage-like tissue with spatially varying properties’ by Kirsten Parratt et al., J. Mater. Chem. B, 2017, 5, 6237–6248.
The authors wish to report that a data set in Fig. 6F, represented by the black B, I and G data points, was incorrectly plotted as the change in sGAG, but should have been plotted as the absolute values. The corrected version of Fig. 6 is given below (the caption remains unchanged).
While the major conclusions and results of the paper are not significantly impacted by this correction, the associated discussion in the main text is now simplified and the following sections of text should be discarded: in section 3.3.6 Multi-layered constructs, in the 2nd paragraph: “However, there were differences in the absolute values of both…layers showed a large increase” should be removed; and in the 3rd paragraph: “This was surprising as the measure increase in sGAG did not translate into an increase in modulus” should also be removed.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
