After years of work, the centerpiece of my PhD is published in @natmethods.nature.com! Read it to learn about the biophysical insights we can get from single-cell data!

But first, I would like to talk a bit about RNA velocity and normalization. 1/

Single-cell multiomics analysis reveals CTCF as a key regulator of lung morphogenesis and progenitor maintenance | Nature Communications Lung development generates a complex tree-like architecture through proximal-distal patterning and branching morphogenesis. However, the gene regulatory programs governing embryonic lung development remain poorly understood. Here, we present a comprehensive single-cell multi-omics atlas of mouse embryonic lungs, integrating gene expression and chromatin accessibility profiles. Through systematic analysis, we identify 13 distinct cell types and map cis-regulatory elements, peak-to-gene linkages, and transcription factors underlying lung development. Leveraging this multi-modal dataset, we uncover lineage-determining transcription factors driving cell differentiation, including the Activated Protein-1 complex. We further delineate gene regulatory networks involving diverse transcription regulators, including CCCTC-binding factor (CTCF). Using the Ctcf conditional knockout mouse, coupled with histological and multi-omics analyses, we demonstrate that CTCF orchestrates lung progenitor main

NEW LAB MEMBER!

We welcome ‪@florherbstein.bsky.social who is joining us as a‬ ‪@carrerasleaders.bsky.social‬ Postdoctoral Fellow. She is alumni of #IBioBA-MPSP and the University of Buenos Aires.‬‬
She will study how nuclear metabolism influences proliferation and therapy resistance in AML.

Congratulations to Masahiro Nagano on his new paper on STAG3-cohesin.

STAG3-cohesin has a much shorter residence time which leads to altered 3D genome organization and STAG3-cohesin is important for male germ cell differentiation.
