There were errors in Development (2025) 152, dev204813 (doi:10.1242/dev.204813).The authors contacted us to say that there were three incorrectly cited references. The updated citations are detailed below.In the first paragraph of the ‘Results: Regeneration, architecture and patterning of patient-derived organoids from single cells’ section, ‘Linnemann et al., 2015’ should have instead cited ‘Sokol et al., 2016’.Corrected:We have recently shown that hydrogel scaffolds seeded with tissue clusters yield human breast organoids with remarkably similar architecture and hormonal responses to those of human breast tissue (Sokol et al., 2016).In the first paragraph of the ‘Results: Comparative transcriptional analysis of tissue and organoid cell populations’ section, ‘Rauner et al., 2021’ should have instead cited ‘Ortiz et al., 2024’.Corrected:To ascertain whether organoids grown in ECM hydrogel mirrors human breast tissue, we performed a side-by-side analysis using previously published single-cell RNA sequencing (scRNA-seq) data on cells obtained directly from normal human breast tissue (Gray et al., 2022), as well from traditional organoids grown in Matrigel (Ortiz et al., 2024), and compared them to scRNA-seq we performed on organoids grown in the ECM hydrogel substrate.In the first paragraph of the ‘Materials and Methods: Integrated analysis’ section, ‘Barnes et al., 2014’ should have instead cited ‘Gray et al., 2022’.Corrected:Previously published scRNA-seq data from traditional organoids grown in Matrigel (Ortiz et al., 2024), healthy primary breast tissue (Gray et al., 2022), as well as the scRNA-seq data generated from this study were analyzed.These citations have been corrected in the pdf and online.The authors apologise for this error, which does not impact the results and conclusions of the paper.

ABSTRACT As part of the 100th birthday celebrations of our publisher, The Company of Biologists, we are reflecting on Development's association with another longstanding institution: the Woods Hole Embryology Course. The Embryology Course has been running since 1893 at the Marine Biological Laboratory (MBL) in Woods Hole, USA. Situated on sandy shores where bioluminescent creatures bloom in the summer, Woods Hole is known as a place where imaginations can run wild, and students can encounter organisms that carry out development in ways that are both unfamiliar and thought-provoking. This famous programme has trained generations of developmental biologists, so we are proud to have had some involvement in its illustrious history. Here, I explore Development and The Company of Biologists' association with the course through financial support and promotion on our community blog, the Node. I also collate testimonials from former students to learn more about the long-term impact that the course has had on their careers.
