The Fraticelli Lab has a new doctor!!! 😍✨we are so happy to have witness your growth Dr. @LuisC_rodriescu. Super proud of you! 🫰🏻

[Maria Guarini @mguarini1]

It was a pleasure to present our new technology at @ISEHSociety 2026 in Frankfurt ✨😍
It makes me really proud of my PhD journey!
Thanks to all the @FraticelliLab to make it possible!💫

[Fraticelli Lab @FraticelliLab]

Super proud of our postdoc @VictoriaParreno for receiving the prestigious Branco Weiss Fellowship 😍 She will explore how life events, such as pregnancies and menopause affect hematopoietic stem cells 👏✨💫 https://t.co/DqY8XH0nkI

[Fraticelli Lab @FraticelliLab]

We are still recovering from yesterday’s emotions! Our very special @mlopezosias successfully defended her PhD 🔥🎓💕we are extremely proud of you and we hope all your wishes become true!! 🙌🏻Enhorabuena Dr.a Marta López-Osias!!

One of the most interesting studies on lineage fate plasticity I’ve seen in a while. This one is an instant must-read.

Is there clonal memory? Yes of course.

But the actual clonal outcome is heavily influenced by demand from the niche/feedback.

(Glad our minor contribution was helpful!)

@PapapetrouMDPhD @AlejoFraticelli It was a pleasure to discuss with you, Eirini! ✨

[Eirini Papapetrou, MD, PhD @PapapetrouMDPhD]

Fantastic day hearing about all the super cool projects cooking at the @AlejoFraticelli lab. Such a creative group of people!

[Alejo Rodriguez-Fraticelli @AlejoFraticelli]

New GROUP LEADER POSITION announced @IRBBarcelona !!!

This one is for CHEMICAL BIOLOGY 🧪!

Chemists apply👩🏻‍🔬👨🏽‍🔬🧑🏻‍🔬!!!!

Interested in single-cell lineage tracing? 🧬

Our new Review in @NatureRevGenet updates the modern toolbox for genetic tracing and clonal analysis — from synthetic barcoding to natural genomic and epigenomic variants.

Glad to have contributed alongside @AlejoFraticelli 🙌

INTERESTED IN SINGLE-CELL LINEAGE TRACING?

New review @NatureRevGenet from the @FraticelliLab. 🎉🎉

https://t.co/v3oa8gUUNj

With @VictoriaParreno we tried to update the modern manual for genetic tracing and clonal analysis. ENJOY!

A nice good-morning with a new preprint from our lab!! 😍🥳 this was a real team effort💥 Hope you all enjoy the reading!

[Alejo Rodriguez-Fraticelli @AlejoFraticelli]

🚨 NEW @FraticelliLab PREPRINT JUST WENT LIVE

https://t.co/cauXJei5Ji

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!

[Fraticelli Lab @FraticelliLab]

The Fraticellis started 2026 with great energy! 🥳 Our lab retreat of last week was full of fun, good vibes, heartfelt moments, and crazy late-night science discussions. 👀🩷 Batteries fully recharged!🔋

[Fraticelli Lab @FraticelliLab]

2025 was an incredibly successful year for the Fraticelli Lab! We loved celebrating it together during our xmas day—especially with some wonderful new faces joining us.🥰 We’re excited for what 2026 will bring and wish everyone happy holidays! 🎄🎅💫
