Chromatin landscape at cis-regulatory elements orchestrates cell fate decisions in early embryogenesis

Fides Zenk

The establishment of germ layers during early development is crucial for body formation. The Drosophila zygote serves as a model for investigating these transitions in relation to the chromatin landscape. However, the cellular heterogeneity of the blastode ...

Single-cell epigenomic reconstruction of developmental trajectories from pluripotency in human neural organoid systems

Fides Zenk

Cell fate progression of pluripotent progenitors is strictly regulated, resulting in high human cell diversity. Epigenetic modifications also orchestrate cell fate restriction. Unveiling the epigenetic mechanisms underlying human cell diversity has been di ...

Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

Fides Zenk

Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...

Dissecting the epigenetic regulation of human brain organoid development in single cells

Fides Zenk

We present a developmental atlas that offers insight into sequential epigenetic changes underlying early human brain development modeled in organoids, which reconstructs the differentiation trajectories of all major CNS regions. It shows that epigenetic re ...

Building the epigenetic fortress with PRC2.2

Fides Zenk

How heterochromatin is established de novo in early embryos is unknown. A study now shows that the sequential recruitment of the key regulator JARID2 recruits PRC2.2 to H2AK119ub and ensures proper H3K27me2/3 deposition. This prevents premature enhancer ac ...
