International Vascular Biology Meeting (IVBM) 2026!! It doesn't get bigger than this! Extremely grateful to Professor Natasha Harvey for the invitation! Can't wait to meet and reconnect with all the phenomenal vascular biologists! Bucket list Australia, here I come!!

For many years in my family, "Kloster Seeon" has been synonymous with "Mecca of Vascular Biology"...I am extremely grateful and excited to be invited this year! Already looking forward to phenomenal talks, amazing science and inspirational discussions with wonderful colleagues!

Inaugural lab meeting of the Koh Lab! I feel super lucky to be hosting two extremely talented and extraordinarily devoted rotation students - Toni Castro-Torres and Leah Willner - of the Yale BBS grad school program! Amazing discussions and exciting projects!! Go~ Team!

Degeneration and Impaired Resilience of Skull Bone and Hematopoietic Bone Marrow Bone marrow health is central to transplantations, blood formation, and cancer progression. However, the bone marrow niche deteriorates with age, impairing haematopoietic stem cell function. Contrary ...

A recent preprint (Yang et al., doi.org/10.1101/2025...) challenges an article from my lab published in 2024 (Koh et al. 2024, PMID: 39537918). We strongly dispute their claims (please see our comment on bioRXiv).

Today, I officially said farewell to my second post-doc lab. I am ever so grateful to my amazing mentor
@ralfhadams.bsky.social for his exceptional and unwavering support. Words do not suffice in expressing my true appreciation and gratitude toward my fellow colleagues:

I just said farewell to the very first restaurant in Münster, Germany that welcomed me 5.5 years ago...Thank you, Hotel Bakenhof, for taking me in during the first COVID lockdown!!

1/3 The science and discussions at the Angiogenesis GRS this year were 🔥🔥🔥. Grateful to have had a chance to co-chair it this year together with @bikohcello.bsky.social after attending every single meeting since I was a Graduate Student in 2015!

It was a tremendous honor to serve with you, Brisa! Such a motivating and humbling experience to support such phenomenal trainees!! Thank you all for your amazing contributions!

A mast cell receptor mediates post-stroke brain inflammation via a dural-brain axis Meningeal mast cells, via the receptor Mrgprb2/X2, orchestrate brain inflammation after stroke by recruiting and promoting the transfer of skull bone marrow neutrophils into the brain, highlighting these mast cells as key regulators of brain immunity and of the skull bone marrow-meningeal-brain network.

Non-canonical functions of DNMT3A in hematopoietic stem cells regulate telomerase activity and genome integrity Challen and colleagues show that the clonal expansion of Dnmt3a-null HSCs in serial bone marrow transplantation assays is not dependent on the loss of DNA methylation functions of Dnmt3a. They identify non-canonical functions for Dnmt3a in the regulation of telomere length and genome stability that restrict the functional potential of HSCs.

Mitochondrial origins of the pressure to sleep - Nature Research on Drosophila neurons shows links between the need to sleep and aerobic metabolism, indicating that the pressure to sleep may have a mitochondrial origin.
