Alvaro’s paper has been published in Nucleic Acid Research
Chromatin organization and gene expression are interdependent. Previously, our group had showed that nucleosomes form groups, termed clutches, whose size correlates with cell state.
In this paper, Alvaro, together with Jason Otterstrom, carried out 2-color super-resolution microscopy to image core histones and DNA at nanoscale resolution.
They identified the “clutch DNA” as the DNA whose compaction is dependent on the clutch. Moreover, they studied how the epigenetic state of the clutch alters the radius of the clutch DNA.
These results provide novel insights into chromatin organization at the nanoscale level and show how the clutches affect DNA packaging.

GenStorm was awarded the BIST Ignite Grant 2017!
In GenStorm our goal is to combine high resolution microscopy with molecular modeling techniques. With this multidisciplinary approach we aim to understand how genes are organized within the cell nucleus and how this affects their function. The project is coordinated by Victoria Neguembor (Cosma lab at CRG) and Pablo Dans (Orozco lab at IRBB).
BIST awards three multidisciplinary projects for the Ignite Program’s second phase

Victoria’s paper has been published in Nucleic Acids Research
Our work on PoSTAC (Polycistronic SunTAg modified CRISPR) has been published in Nucleic Acids Research.
PoSTAC is a gene visualisation tool that combines CRISPR/dCas9 with SunTag labeling and polycistronic vectors. PoSTAC enables live cell and super-resolution imaging of multiple genes with high spatiotemporal resolution and high sensitivity.

Ilda paper has been published in Scientific Reports
Ilda showed that the Paternally Expressed Gene-3 (PEG 3) is a novel regulator of somatic cell reprogramming. Peg 3 enhances cell reprogramming by acting on cell metabolism.

Ruben has scored the second at “Tell it to your parents” contest
Ruben Sebastian Perez, a master student in our lab, has got the second place in the “Tell it to your parents” contest organized by Sociedad Española de Bioquímica y Biología Molecular (SEBBM).
Master students and bachelor students had to make videos for the general audience, in which they explain different Research concepts in the simplest way possible.
Below you can get a link to Ruben’s video : “A decade of iPS cells”

Elisa’s paper on Liver Regeneration has been published on Cell Reports
Until now hepatocyte replication has been considered the main mechanism of liver regeneration after hepatectomy in mammals. We recently found that bone marrow cells can migrate into the liver upon resection and fuse with the hepatocytes. The derived hybrids proliferate and are essential for efficient liver regeneration, which is also predicted by mathematical modelling.

Francesco Sottile’s paper has just been published in Scientific Reports
How do cells interact with other cells? We discovered that mouse mesenchymal stem cells (MSCs) can either fuse and form heterokaryons (cells with 2 nuclei) with mouse embryonic stem cells (ESCs) or can be invaded by ESCs through the entotic process (when one cell enters into another cell). Upon entosis the nucleus of the ESCs is degraded, while heterokaryons convert into synkaryons (cells with one nucleus containing both parental chromosomes) through cell division. These mechanisms are controlled by the activity of cytoskeleton components. Overall these are two profoundly different outcomes of cell-to-cell interactions, which might be important for different biological processes.
