We have identified errors in the Material and Methods section of the manuscript – under the heading “Primary breast cancer spheroid and tumoroid embedding”. These errors were unintentional and have been rectified. See below.

Original text:

  • FluoSphere polystyrene beads (1 µm diameter, Thermo Fisher Scientific) are carefully suspended, without forming bubbles, in 1.2 mg/ml collagen solution at a concentration of 2x108 beads/ml. 650 µl of this mixture is poured into one well of a 6-well plate […]

  • Once the spheroids/tumoroids have settled to the base of the tube, excess media is aspirated away and spheroids/tumoroids are resuspended in 650 µl of the 1.2 mg/ml collagen/bead mixture. […]”

Corrected text:

  • Silica beads (4 µm diameter, Kisker Biotech) are carefully suspended, without forming bubbles, in 1.2 mg/ml collagen solution at a concentration of 2x108 beads/ml. 1300 µl of this mixture is poured into one well of a 6-well plate […]

  • Once the spheroids/tumoroids have settled to the base of the tube, excess media is aspirated away and spheroids/tumoroids are resuspended in 1300 µl of the 1.2 mg/ml collagen/bead mixture. […]”

The article has been corrected accordingly.
