Bone marrow EPCR+ hematopoietic (blood-forming) stem cell in an anticoagulant niche

How does the body keep replenishing the supply of blood cells all our lives? Two pathways must work together

New lung cells are continuously created to replace the damaged ones: Lung tissue six weeks after stem cell transplantation (left) and 16 weeks after transplantation (right). Cells that originated in the transplanted stem cells are green, as opposed to the uncolored host lung cells. Photon-2 microscope image

Transplanted cells made their way to the lungs in mice and began producing healthy tissue
