Understanding how blood stem cells decide to grow or become mature cells

Official title: Investigating the mechanisms of lysosome segregation and cell fate regulation in dividing hematopoietic stem cells

Funded at St. Jude Children's Research Hospital · NIH-11398070 · Data updated 2026-11-12

Scientists are studying human blood stem cells to learn how they decide to keep renewing themselves or to turn into mature blood cells for transplant patients.

Who could benefit from this research

Could help

People with blood disorders who may need hematopoietic stem cell transplants could benefit from future advances stemming from this research.

Less likely to help

Healthy individuals not needing stem cell therapies may not directly benefit from this study.

What this research studies

This project looks at how hematopoietic stem cells divide and how the components inside the cells influence whether both daughters stay stem cells or only one remains a stem cell. It uses advanced 3-D imaging to watch living cells over several days at single-cell detail. The goal is to identify factors that promote expanding stem cells for better transplantation without losing their ability to mature into needed blood cells. Findings could help develop better culture methods to produce enough healthy cells for patients who need transplants.

Why it matters

Potential benefit: If successful, the work could lead to more reliable production of stem cells for transplantation, potentially expanding access to curative therapies.

How similar studies have gone: Previous studies show that understanding stem cell division can influence stem cell expansion, but precise live-cell tracking over days is still challenging and promising.
