Celebrating Stem Cells – IV Bone Home

Newly discovered stem cell source in bone marrow vessels

19 December 2019

Bone Home

Tiny nurturing 'niches' in our bone marrow play home to haematopoietic stem cells (HSCs) – cells with the power to transform into blood cells, keeping our blood supply fresh and healthy. Many HSCs first appear before birth – maturing from endothelial cells lining the walls of our early blood vessels before moving to their cosy niches in the bone marrow. Yet in this slice through a chicken’s bone marrow (with its cells highlighted in blue), we see a surprising twist – new HSCs (red) produced from the vessels (green) of the bone marrow itself. This previously unknown 'wave' of stem-cell production may help to prepare bone marrow for welcoming HSCs migrating there from elsewhere in the body. Understanding these ‘new’ steps in growing and nurturing human HSCs may lead to more effective treatments for diseases like leukaemia that affect our precious blood stem cells.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
