 A Correction on A cell adhesion-promoting multi-network 3D printing bio-ink based on natural polysaccharide hydrogel by Qi Y, Zhang S, He Y, Ou S, Yang Y, Qu Y, Li J, Lian W, Li G, Tian J and Xu C (2022).

There was an error in the stereomicroscope image of the AHAMA/TGG/MMSN-4 group in Figure 3C as published. During the layout process of the manuscript, the figure is inadvertently overwritten by the image of the AHAMA/TGG/MMSN-3 group in Figure 3C. The corrected Figure 3C appears below.

(C) Postural microscope images of AHAMA/TGG/MMSN hydrogel with different concentrations of MMSN 3D printing.

Four microscope images labeled AHAMA/TGG/MMSN-1 to AHAMA/TGG/MMSN-4 show hydrogel structures. Each image displays a grid-like pattern with varying degrees of uniformity and density, illustrating structural differences. A scale bar indicates 2 millimeters.

There was an error in the confocal laser scanning microscope (CLSM) image of the AHAMA/TGG/MMSN treatment group (3D) in Figure 5A as published. An incorrect image was used for Figure 5A. The corrected Figure 5A appears below.

(A) CLSM images of stained BMSCs cells showing morphology adhered on the 3D printing AHAMA, TGG, AHAMA/TGG and AHAMA/TGG/MMSN scaffolds on day 1 and 3, respectively.

Microscopic images showing cell morphology with red-stained cytoskeletons and blue-stained nuclei. Cells are arranged in a grid, labeled AHAMA, TGG, AHAMA/TGG, and AHAMA/TGG/MMSN, comparing 1D and 3D configurations. Scale bars indicate 50 micrometers.
