Thesis Defense Carine

Carine sporting her "Doktorhut"

As the first Vastenhouw Lab Predoc student, Carine has successfully defended her thesis. Congratulations Carine, also on the impressive “Doktorhut” (special German version of the PhD graduation hat).

Genome Architecture Meeting at ICTP, Trieste

Lennart participated in the meeting “Genome Architecture in Space and Time”, which took place at the International Center for Theoretical Physics in Trieste from June 20th to 24th. The venue would suggest a Physics and Theory heavy meeting – and certainly there was some of that – but the conference covered various aspects of genome architecture. From newest biophysical and imaging approaches, via medical relevance of aberrations in genomic structural elements, to polymer folding models, a truly eclectic mix of questions and approaches was presented. Unusual for an international meeting, the invited speakers had about 45 minutes each. Throughout, this time was put to good use, allowing comprehensive introductions, sometimes reaching back decades to lead up to the most up-to-date questions.

Pavel visits the lab of Prof. Tatjana Sauka-Spengler in Oxford

In mid-March 2016, Pavel visited the lab of our collaborator Prof. Tatjana Sauka-Spengler in Oxford, UK. Tatjana’s lab established a genetically encoded system for biotinylation of specific targets in fish cells, allowing, among other applications, tissue-specific isolation of nuclei.

Supervised by a cheerfully enthusiastic PhD student Vanessa Chong, Pavel performed several rounds of nuclei isolation and is looking forward to introduce this method to Vastenhouw lab. 

Apart from having great time in Tatjana’s lab, Pavel also explored the charming campus of the Oxford University.

Thanks the entire Sauka-Spengler lab for a great time!

Methods Article in ‘Development’

We are happy to post about our lab’s recent publication in Development. The article describes how to label and analyze single mRNA molecules, within single cells, at different stages of the zebrafish embryo’s development. With this technique, we hope to open new avenues into gene expression patterns and cellular differentiation programs.

The project was chiefly driven Carine Stapel, currently a PhD student in the Vastenhouw Lab. Carine developed the experimental protocol. The associated, freely available image analysis and quantification pipeline was developed in collaboration with Gene Myer’s research group as well as the Scientific Computing Facility. In fact, all work was done in-house at the MPI-CBG, demonstrating the institute’s wide array of qualifications as well as its collaborative spirit.

The article and protocol are available from Development, and the article also contains the analysis pipeline in its Supplementary Information. Article Page at Development

Short Visit from Yuko Sato

Our collaborator Yuko Sato paid us a short visit from Japan. Yuko is a Kimura Lab Members at the Tokyo Institute of Technology, who develop innovative in vivo imaging approaches targeting post-translational modifications.

During the visit, Yuko and Lennart executed pilot experiments for light sheet-based in vivo imaging. We hope the photo conveys our joy at the last, successful attempt at our experiments. Thank you for the visit!
