🚨 NEW
@FraticelliLab
PREPRINT JUST WENT LIVE

biorxiv.org/content/10.6...

Here, we describe PLSTCs, Soluplus-based expansion cultures of primary mouse *Acute Myeloid Leukemia* Stem Cells. And then we use LARRY barcoding to identify drivers of leukemogenicity and drug resistance!

🔔HIRI has opened a new call to recruit Group Leaders. If you are interested in opening an RNA Biology and Infection lab, join us! Deadline: February 15. More info here 👇

New preprint on technologies to scale up CRISPR screens.

We use them to map 665,856 pairwise genetic perturbations and outline a path to comprehensive interaction mapping in human cells.

We also introduce an approach for cloning lentiviral libraries with billions of elements.

Our paper on the second Berlin patient came out in Nature today and I’m really happy we can share this story on World AIDS Day. I want to thank everyone on the team and all co-authors for their work over the years.

Also, here’s an accessible video intro:

Single-cell susceptibility to viral infection is driven by variable cell states Not all cells that can be infected by a virus become infected with that virus. Single-cell clone tracing reveals intrinsic cell states with variable expression patterns that increase susceptibility to...

So awesome to have this great paper from Sam Reffsin and Sara Cherry out! In it, we use retrospective clone tracing to show that there are particular single cell states that are more susceptible to viral infection (both SARS-CoV-2 and flu)!

Highlights and key findings from our study in the thread below 👇

🙏 Thanks to @caleblareau.bsky.social l, @hattaca.bsky.social, @helenaradbruch.bsky.social ky.social, Benedikt Obermayer, Marie Cotta, Frank Hepper, David Capper, Wolfram Kunz, Markus Schülke & all team members for their contributions!

Together, scmtMPM & scwMSS provide a quantitative framework for somatic mtDNA mosaicism, advancing mitochondrial genetics & disease research.

Using POLG-mutant cells, healthy donors & patients, we show:
🔹 Complex single-cell mutational landscapes
🔹 Negative selection against truncating & pathogenic variants

🔹 Constrained mutations in Complex I

🔥 Our second preprint, led by Josch, introduces a new framework to measure mtDNA mutational burden & constraint at single-cell resolution.
We present:
🔹 scmtMPM (mutations per Mb)
🔹 scwMSS (heteroplasmy-weighted local constraint)

In short: Cryo-mtscATAC-seq enables cell state–informed clonality from frozen specimens, opening new avenues to leverage biobanked tissue in health & disease.

Cryo-mtscATAC-seq + our mitoBender computational tool:
🔹 Works on archival frozen tissue
🔹 Extends mtDNA genotyping to brain, glioblastoma, neuroblastoma & vascular tissue
🔹 Reveals clonal gliogenesis, microglial expansions, chemo-induced heterogeneity & smooth muscle oligoclonality

Cryo-mtscATAC-seq for single-cell mitochondrial DNA genotyping and clonal tracing in archived human tissues High-throughput clonal tracing of primary human samples relies on naturally occurring barcodes, such as somatic mitochondrial DNA (mtDNA) mutations detected via single-cell ATAC-seq (mtscATAC-seq). Fr...

🚨 New preprints from our lab!
First, we introduce Cryo-mtscATAC-seq, led by Maren (@ms-maren.bsky.social ), enabling high-throughput clonal tracing from frozen human samples by isolating nuclei with their mitochondria (“CryoCells”).
