1. Epigenetic regulation in stem cells and differentiation.

2. Neurodegenerative diseases (e.g. HD) using pluripotent stem cell models.

3. Paleo-epigenetics: reconstructing DNA methylation in archaic genomes.



Chromatin plasticity in embryonic stem (ES) cells and in ES cell differentiation

Using endogenously-labeled fluorescent libraries in mouse embryonic stem cells which we generated, we can visualize differentiation events, nuclear body dynamics, protein binding kinetics, etc. and screen for pluripotency and differentiation relevant factors, in living cells.

Projects 1,2

Identification and characterization of stem cell chromatin proteins

Project 3Using a biochemical assay ("D-CAP: differential chromatin associated proteins"), which we developed (Alajem et al., Cell Rep., 2015), we are analyzing the differential composition of chromatin proteins in different stages of stem cell differentiation in order to identify stem cell specific chromatin proteins. Once identified, we study their role in stem cell maintenance using a variety of molecular, microscopic and biochemical methods.





Using human pluripotent stem cells to model neurodegenerative diseases

Here we are using human embryonic stem cells (hESCs) and human induced pluripotent stem cells (iPSCs) to model neurodegenerative diseases. We are studying poly-glutamine (PolyQ) diseases including Huntington's disease (HD) and Machado Joseph disease (MJD), as well as Parkinson's disease (PD).

Project 5

In our ERC project, we aim to understand chromatin plasticity and the function of non-polyadenylated transcription in pluripotency. We are combining biochemistry, single cell advanced imaging assays and high throughput technologies to study chromatin and transcription at a genome-wide scale in ES cells and during differentiation and reprogramming, as well as decipher the function of candidate chromatin proteins and candidate non-polyadenylated transcripts in pluripotency.

ERC project

Stem cell epigenetics (including the development of antibody microarrays)

In this project, we aim to analyze the entire epigenetic landscape in the various stages of stem cell differentiation. In collaboration with Yoav Soen (Weizmann Institute) we began to develop specialized antibody microarrays for all known histone modifications. In the future these antibody arrays will be used for a variety of systems, from analysis of different cell types to screening cancer patients.
