Fusing human retinal cells with adult stem cells could be a potential therapeutic strategy to treat retinal damage and visual impairment. We show that cell fusion between Muller Glia cells and adult stem cells can take place in human retinal model systems. The hybrids cells can differentiate towards neural fate and have potential to regenerate the tissue.

Previous techniques could visualize active areas of transcription, but not give precise information about their shape and size. We imaged nascent RNA spatial accumulations, which we termed RNA nanodomains. We characterized the RNA nanodomains and revealed how they interact with active RNA Polymerase II, the main component of the transcription machinery, and in turn, with small chromatin clutches, one of the smallest units of organization of the DNA fibers.

Vicky's paper has been published in Molecular Cell
We showed that transcriptionally generated supercoiling regulates loop formation. The girl's blowing represents the force of transcriptionally generated supercoiling that promotes loop extrusion (bubbles forming) through cohesin (ring of stick). Bubbles depict different nuclear topologies. Excess of cohesin, supercoiling, and loops leads to chromatin blending (upper bubbles), while inhibition of transcription or topoisomerases brings decreased supercoiling and chromatin compaction (lower bubbles).

ECaBox "Eyes in a Care Box": Regenerating human retina from resuscitated cadaveric eyes.
We will create a device, the EcaBox, to resuscitate eyes from the dead. In collaboration with a number of Partners working in Universitat de Barcelona (UB), Institute for Bioengineering of Catalonia (IBEC), King’s College London (KCL) in the UK, the Association for the Advancement of Tissue Engineering and Cell Based Technologies & Therapies (A4TEC) in Portugal, AFERETICA in Italy and the Bar-Ilan University (BIU) in Israel, we will develop artificial blood, artificial vitreous to kick-starting the activity of retinal neurons and restoring eye function. ECaBox will be a transparent, cubic box that mimics conditions in the living human eye, maintaining the eye’s temperature and pH levels while avoiding blood clots and removing metabolic waste and toxins.

The Master Regulator protein BAZ2B can reprogram human hematopoietic lineage-committed progenitors into a multipotent state.
Arumugam et al. Cell Reports 2020
We used reverse-engineered networks to elucidate the molecular mechanism of cell-fusion mediated reprogramming of B lymphocytes to hematopoietic stem cell-like state. BAZ2B was identified as a Master Regulator that can reprogram human lineage-committed progenitors to multipotent hematopoietic cells, thus enhancing their stemness and long-term engraftment.
