Very excited to share our latest work focused on hPSC-macrophages in human cardiac microtissue function, now published in @NatureCVR and featured on the cover! (@Ella_Maru) @EpelmanLab

A @UHN @McEwenInstitute team developed the first functional AVN-like pacemaker cells in their new study. 🫀 Their work lays the foundation for the development of a novel treatment that could someday replace the #pacemaker. 🔗 Read more: uhnresearch.ca/news/4-02-2026… @StephIrisPro

1/ Can #Axolotls teach us new things about #HeartRegeneration? A great collaboration between @Tanaxolotl and Miguel Torres lab. We’re happy to share our new work in which we ask how axolotls regenerate their hearts and could they help mammals with that? doi.org/10.64898/2025.…

@luigiadamomdphd @EpelmanLab @AHAScience @UHN_Research @PMunkCardiacCtr @TBEP_UofT @trogersresearch @CIHR_IRSC Thank you!

@EpelmanLab @Homaira_H @AHAScience @UHN_Research @PMunkCardiacCtr @TBEP_UofT @trogersresearch @CIHR_IRSC Congrats!

Congrats @Homaira_H for winning best poster at #bcvs2025 @AHAScience. You do @UHN_Research @PMunkCardiacCtr @TBEP_UofT @trogersresearch @CIHR_IRSC proud!

Abdominal aortic aneurysms are silent killers and a leading cause of death in men over 65. New research from @UHN’s @TGHRI_UHN uncovers how smoking damages the aorta and activates immune cells that drive rupture, paving the way for new treatments. 🔗 : uhnresearch.ca/news/understan…

UHN marks the passing of Dr. James Till, whose work with Dr. Ernest McCulloch first demonstrated the existence of blood-forming stem cells in 1961 at Ontario Cancer Institute, now Princess Margaret Cancer Centre. His work has helped launch the field of #stemcell science.

@MacparlandSonya @DianaNakib @naglaa_shoukry @PSCPartnersCa @nkg2d1 @BuechlerLab @DrAGehring @garybader1 Congrats @DianaNakib!!!!

Fun and exciting day for the lab! Congrats to the new Dr. @DianaNakib for a brilliant PhD defense! Huge thanks to @naglaa_shoukry for being a fantastic external and giving a super talk on the cellular response to liver injury and the exam committee for super cool questions!

Congratulations to Dr. Clinton Robbins and the team at UHN’s @PMunkCardiacCtr on their new study published in @NatImmunol. Their work reveals how cigarette smoke can trigger deadly aortic aneurysms—and points the way to life-saving treatments. Read more: nature.com/articles/s4159…

What began in 9th grade with a simple question—why do wounds leave angry scars?—has come full circle in the most incredible way. Beyond thrilled to have matched to Plastic Surgery @UofTSurgery @UofT! It truly takes a village to raise a physician and a community to inspire questions that elevate care. A heartfelt thank you to mine ❤️ Can’t wait for early morning rounds with the dream team @UHN_Surgery again!

@thorplab Very interesting work, congrats!

Happy New Year! May 2025 be happy, healthy and productive for all.

Ever wondered how gut microbes control immune responses at extra-intestinal locations? Here, #theonlylabever reports how a gut protozoan commensal microbe remotely shapes pulmonary immunity to exacerbate asthma and limit the dissemination of mycobacteria. @CellCellPress ⬇️(1/X)

So excited to share the first paper from the lab! We identified CD34 as a marker of the heart’s SAN pacemaker cells enabling their isolation from stem cell differentiation cultures, advancing future disease modeling and biological pacemaker applications. nature.com/articles/s4146…
