Blood Stem Cell Identity Lab

Blood stem cell Identity team

We are a dynamic, curiosity-driven, international team of scientists on a mission to crack the code of human hematopoietic (blood-making) stem cells, the ultimate shapeshifters of biology (at least for us…). Our work is all about uncovering how these remarkable cells stay young, stay flexible, and stay powerful.

The Recipe?

Self-Renewal: Think of it as extreme self-care at the cellular level. HSCs have to stay relaxed, keep their plasticity, maintain their identity, and avoid burnout, all while being ready to jump into action at any time to generate new blood for life.

Multipotency: They’ve made the career choice to become blood, but they haven’t settled on the job title yet: red cells, white cells, platelets… they keep their options wide open. We’re fascinated by how they hold onto this potential without committing too early.

The result: Engraftment Ability upon Transplantation: When called to duty, these cells deliver. Successfully repopulating an entire blood system in a new host? That’s next-level skill. It takes all the above qualities plus a little extra…. We want to know what gives them this superpower!

Why are we obsessed with HSCs?

Because we’re infatuated with mechanisms of life. What does it take for a cell population to stay stem and ready for anything? Once cells start differentiating, there’s arguably no turning back, and we want to understand the gene expression programs that keep that door open as long as possible.

Because HSC transplantation is still the last hope for many patients and too often a risky, grueling procedure. We want to make it better, safer, and more effective. We want it to become available and affordable for more patients and to be used to treat more diseases.

Because HSCs are a goldmine for understanding adult stem cell biology. They were the first stem cells to be discovered and used in medicine and the most accessible. So as a model to study stemness, they hold the key to unlocking the full promise of regenerative medicine, way beyond the field of blood.
