The Andersson lab aims to understand how specialized organs systems develop the correct cellular identity and architecture necessary for function. As developmental biologists, we are interested in why and how genetic mutations lead to specific defects in embryogenesis. In order to study this in depth we develop new technologies to analyze organs, or new methods to manipulate embryogenesis. We are focused on Alagille syndrome, a congenital disorder affecting development of several organ systems including the liver and vasculature. In addition to the technologies we are developing, we use mouse models, 3D cell culture, CRISPR cell lines, single cell omics, and patient samples to address fundamental questions with relevance for human health.

Thank you to the reviewers for seeing the potential in these projects!
Editorial by ER Andersson out now in Hepatology. This editorial discusses exciting new work from Duc Dong’s lab, in the context of previous findings from Stacey Huppert and Holger Willenbring’s labs.
In order to disseminate neural plate targeting with in utero nano-injection (NEPTUNE) (Mangold et al Cell Reports Methods 2021), we are happy to present the full protocol in the Journal of Visualized Experiments (JoVE): Mangold et al, Jove 2022
Also, if you are interested in NEPTUNE or in utero genetic manipulation for your experiments, we set up a core facility to provide NEPTUNE as a service to researchers; INFINiGENE (INFrastructure for in utero GENEtic manipulation).
Our Special Issue of the European Journal of Medical Genetics “Advances in genetic, epigenetic and environmental aspects of rare liver diseases” is out. ER Andersson co-guest-edited this Special Collection together with Prof Dr Ansgar Lohse, on behalf of the European Reference Network for Rare Liver Disease (for which ER Andersson is the External Scientific Advisor). The collection highlights progress in rare diseases such as PSC, PFIC, Wilsons disease and more, and includes an editorial introduction that you can read here.
Collaborative paper led by Franziska Hildebrandt in Johan Ankarklev’s lab at Stockholm University published in Nature Communications, describing the application of spatial transcriptomics to large liver tissue slices. We confirm liver zonation principles and demonstrate how this will be useful to further studies of liver architecture.
Congratulations to Elisabeth Verboven for being awarded a David and Astrid Hagelen Foundation Fellowship for her postdoctoral project! This fellowship will support Dr Verboven for two years, and we are grateful to the foundation and reviewers for finding the project and Dr Verboven meritorious!
Congratulations to Sandra De Haan for being awarded two travel grants to present her work at the ARO 2022 MidWinter Meeting in California! Sandra will present her work on the inner ear development and homeostasis in a mouse model for Alagille syndrome.
Emma R Andersson is awarded a Karolinska Institutet Consolidator Grant! We thank both the internal and external reviewers!
Andersson lab is awarded a 3R Grant from the Swedish Research Council to continue their work developing in utero nano-injection as an alternative method to traditional mouse genetics – aiming to reduce the numbers of animals needed in life sciences. Thank you for the continued support!
In order to disseminate double resin casting microCT (DUCT) (Hankeova & Salplachta et al eLife 2021), we are happy to present the full protocol in the Journal of Visualized Experiments (JoVE): Hankeova & Salplachta et al JoVE 2021.
On the cover: Our latest paper is out in Cell Reports Methods. We developed a technique to efficiently manipulate gene expression in the embryonic mouse nervous system. We called the technique NETPUNE for neural plate targeting by in utero nanoinjection. Major congratulations to first author Katrin Mangold, PhD student in the lab.
We welcome our new postdoc Elisabeth Verboven, who performed her PhD in the Georg Halder Lab at VIB – KU Leuven, Belgium.
We welcome our new postdoc Lenka Belicova, who performed her PhD in the Marino Zerial Lab at the Max Planck Institute of Molecular Cell Biology and Genetics, Germany.
We welcome our new undergraduate student, Anne-Lin de Valk from the University of Applied Sciences in Utrecht, The Netherlands.
ERA Lab contributes to consensus paper on nomenclature for organoids, as HPB Consortium member: Marsee et al, Cell Stem Cell 2021.
Our analysis of gender bias in review processes is out: Andersson et al Front. Res. Metr. Anal. 2021. We find that among the highest-ranked applicants, women with equal quantifiable merits are ranked lower than men with equal merits. Fun anecdote: another high-impact journal rejected this paper, after revisions, because reviewer X “didn’t believe gender bias exists”.
Our latest pre-print is up on bioRxiv! Simona Hankeova and colleagues investigated whether bleeding in Alagille syndrome might be explained by vascular defects pre-disposing to ruptured blood vessels. Using the mouse model we developed, a systematic review of the literature, and retinal fundus photography from patients, we identified multiple previously unrecognized vascular phenotypes and show that vascular frailty could be linked to sparse vascular smooth muscle cells that are highly sensitive to high blood pressure.
Our collaborative paper with Igor Adameyko lab is out in Nature Genetics! Polina Kameneva, Artem V. Artemov and colleagues used multiple approaches to lineage trace neural crest cells and identify sympathoblast lineages of relevance to neuroblastoma. We contributed with in utero transduction and lentiviral barcode lineage tracing of neural crest (Fig 4, see also NEPTUNE technique described in Mangold et al Cell Reports Methods 2021 above). This project was supported by, and is part of, our Knut and Alice Wallenberg project, a collaboration with Igor Adameyko, Jonas Frisén, Niklas Björkström and Ulrika Marklund groups.
Two new arrivals!
We welcome our new postdoc Paulina Zydowicz-Machtel, who performed her PhD in the Jerzy Ciesiołka lab at the Institute of Bioorganic Chemistry, Polish Academy of Sciences, Poland.
We also welcome our new undergraduate student, Luisa Dehandschutter Gortari, from KU Leuven, Belgium.

Sept 30, 2020
Andersson lab is awarded a Knut and Alice Wallenberg project grant to study lineages and fate choices accross organ systems during development. This major project grant is a collaboration with Igor Adameyko, Niklas Björkström, Jonas Frisén and Ulrika Marklund. We are humbled and grateful to the KAW Foundation and the reviewers – and so excited to do this project!
One publication out, and one deposited in bioRxiv!
- Our collaborative project with Jozef Vecera and Jiri Pachernik is out in Stem Cell Research.
- PhD student Katrin Mangold has developed a technique to study gene function in embryonic development more rapidly than is possible with conditional knockouts. NEPTUNE: neural plate targeting by in utero nanoinjection. Here it is, on bioRxiv. 95% of cells in brain are transduced, conditional expression can be acheived with mini-Promotors, and we obtained a really interesting phenotype knocking down Sptbn2… Importantly, this can also reduce the numbers of mice used in science dramatically.
Andersson Lab is awarded the Swedish Foundation’s Starting Grant – an equivalent to the European Research Council Starting Grant. This collaboration between the Erling-Persson Family Foundation, the Kempe Foundations, the Foundation Olle Engkvist Byggmästare, Ragnar Söderberg Foundation and Riksbankens Jubileumsfond welcomes applications from researchers ranked A in the ERC Starting Grant, and recommended for funding, but for whom there was not sufficient funds in the ERC budget.
Read the press release here, and an interview here. We are deeply grateful to all the participating foundations for their initiative, in particular the Ragnar Söderberg Foundation that funded our Swedish Foundation Starting Grant in this round.
