In the article NEL-Like Molecule-1 (Nell1) Is Regulated by Bone Morphogenetic Protein
9 (BMP9) and Potentiates BMP9-Induced Osteogenic Differentiation at the Expense of
Adipogenesis in Mesenchymal Stem Cells. [Cell Physiol Biochem 2017;41(2):484-500. doi:
10.1159/000456885] by Wang et al., there is an image assembly (copy/paste) error in Figure
4A, in which the image for “NELL1” group was erroneously duplicated with an overlapping
image from the “GFP” group. This error occurred when authors replaced the images in Figure
4 with high resolution images from a large folder of control groups. The authors state
that this error does not adversely impact the conclusion of the original work. The authors
apologize for any inconvenience caused by the error to the journal and scientific community.
The corrected Figure 4 is shown below.
