CODA for the masses! Valentina Matos-Romero, Ashley Kiemen and team have put together an ultra detailed protocol to use CODA for 3D single-cell mapping of tissues, organs, and organisms. Use CODA by downloading this protocol here: www.biorxiv.org/content/10.1...

We used CODA to generate 3D single-cell immuno maps around pre-cancer lesions of the human pancreas. Highly heterogeneous. Work by Prof. Ashley Kiemen and colleagues. Read more about 3D immuno maps around pre-cancer lesions here: www.biorxiv.org/content/10.1...

MEF2C controls segment-specific gene regulatory networks that direct heart tube morphogenesis
The gene regulatory networks (GRNs) that control early heart formation are beginning to be understood, but lineage-specific GRNs remain largely undefined. We investigated networks controlled by the vi...

More to come soon, both in continuing to examine the genomic regulation, but also defining the cellular behaviors that are necessary for early heart tube formation. For now, huge thanks to @benoitbruneau.bsky.social for supporting me as we pursued this ambitious and open-ended project! (8/8)

In what @benoitbruneau.bsky.social aptly described as our “lets go nuts” experiment, we confirmed this interaction by demonstrating that reduced Nr2f2 dosage partially rescues the Mef2c KO heart tube phenotype. (7/n)

New preprint with @gfudenberg.bsky.social We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding. This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇 www.biorxiv.org/content/10.1...

NIPBL dosage shapes genome folding by tuning the rate of cohesin loop extrusion
Cohesin loop extrusion is a major driver of chromosome folding, but how its dynamics are controlled to shape the genome remains elusive. Here we disentangle the contributions of the cohesin cofactors ...

truly amazing paper led by current postdoc Lisa Iwamoto-Stohl. "To our knowledge, this represents the first systematic evidence of proteomic asymmetry between sister blastomeres in the 2-cell mouse embryo." pubmed.ncbi.nlm.nih.gov/41344326/

Fertilization triggers early proteomic symmetry breaking in mammalian embryos - PubMed
While non-mammalian embryos often rely on spatial pre-patterning, mammalian development has long been thought to begin with equivalent blastomeres. However, emerging evidence challenges this. Here, using multiplexed and label-free single-cell proteomics, we identify over 300 asymmetrically abundant …
