The first sino-spain meeting was held at GDL, Guangzhou, China. Talks from CRG PIs and GDL PIs were focused in the fields of chromatin structure, stem cell and regenerative medicine. Interactions between the two institutes were fostered to start a common PhD program that will be organised across the 2 continents. Students will spend part of the time at GDL in China and part of the time at the CRG in Spain carrying out research projects based on collaborations between PIs of the institutions.
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.

Happy to be interviewed in the blog Research in Barcelona and be able to share my views on my work and on research in general. You can read the interview here
Martina, Ruben and Pia discuss in this State-of-the-Art Review of The FEBS Journal the latest advances and applications of in vivo reprogramming strategies for regenerative medicine with a special focus on dedifferentiation, transdifferentiation and cell fusion processes. Cover of The FEBS Journal
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).
