Fascinating work on infection and clonal hematopoiesis in the human population now online in Experimental Hematology!
First (to my knowledge) manuscript describing a correlation between number of infections and incidence of clonal hematopoiesis (CHIP). Really important from the perspective of highlighting a possible modifiable driver of CHIP during aging. @ISEHSociety exphem.org/article/S0301-472…

Institutions are moving away from gamma-irradiators. But can X-ray irradiation replace them for mouse transplant models? 🐁 We show that with proper calibration, X-ray conditioning produces equivalent hematopoietic chimerism and AML transplant outcomes: doi.org/10.1016/j.exphem.202…
