Correction to: Downregulation of fibronectin 1 attenuates ATRA‑induced inhibition of cell migration and invasion in neuroblastoma cells

Correction to: Molecular and Cellular Biochemistry (2021) 476:3601–3612 https://doi.org/10.1007/s11010-021-04113-5

In the original publication of the article, the invasion image of FN1-siRNA-transfected SY5Y cells in Fig. 5B, the invasion image of ATRA-treated NGP cells in Fig. 7B and the invasion image of control-siRNA-transfected SY5Y cells in Figure 7D were published incorrectly. The correct versions of Figs. 5 and 7 are provided in this correction.

Fig. 5

Downregulation of FN1 increased migration and invasion of NB cells. A wound healing assay for two NB cell lines transfected with FN1-siRNA. Data were presented as representative microscopic images taken with an IncuCyte ZOOM (left), relative wound densities (middle) and relative wound densities at the 24 h time point (right). B A transwell invasion assay for two NB cell lines transfected with FN1-siRNA. Data were presented as representative microscopic images (left) and relative numbers of invasive cells (right). *P < 0.05; **P < 0.01. Scale bar = 200 μm

Fig. 7

Downregulation of FN1 partially blocked ATRA-mediated inhibition of cell migration and invasion in SY5Y cells. A Data from a wound healing assay, showing representative microscopic images (left), relative wound densities (middle) and relative wound densities at the 24 h time point (right). B Data from a transwell invasion assay, showing representative microscopic images (left) and relative numbers of invasive cells (right). C Data from a wound healing assay for SY5Y cells, showing representative microscopic images (left), dynamic changes of relative wound densities (middle) and relative wound densities at the 24 h time point (right). D Data from a transwell invasion assay for SY5Y cells, showing representative microscopic images (left) and relative numbers of invasive cells (right). NS no statistical significance. Scale bar = 200 μm
