CIRM funded trial for sickle cell disease gives patient a chance for a better future
Evie Junior is participating in a CIRM funded clinical trial for sickle cell disease that uses a stem cell gene therapy approach. Image credit: UCLA Broad Stem Cell Research Center For Evie Junior, personal health and fitness have always been a top priority. During his childhood, he was active and played football, basketball, and baseball … Continue reading CIRM funded trial for sickle cell disease gives patient a chance for a better future
Capturing an image of blood stem cells
Image of a blood stem cell in its natural environment: Photo courtesy UC Merced UC Merced’s Professor Joel Spencer and his team developed a way of capturing an image of blood stem cells or image of blood stem cells inside their niche in the bone marrow. “Everyone knew black holes existed, but it took until … Continue reading Capturing an image of blood stem cells
Antibody effective in cure for rare blood disorders
3D illustration of an antibody binding to a designated target. Illustration created by Audra Geras. A variety of diseases can be traced to a simple root cause: problems in the bone marrow. The bone marrow contains specialized stem cells known as hematopoietic stem cells (HSCs) that give rise to different types of blood cells. As … Continue reading Antibody effective in cure for rare blood disorders
Mechanical forces are key to recovery after blood cancer treatment
Mesenchymal stem cells grown on a surface with specialized mechanical properties. Image courtesy of Krystyn Van Vliet at MIT. Blood cancers like leukemia and lymphoma will account for about 10% of all new cancer cases this year. Doctors often treat these diseases with irradiation, which kills the patient’s bone marrow — the source of blood … Continue reading Mechanical forces are key to recovery after blood cancer treatment
Support cells have different roles in blood stem cell maintenance before and after stress
A new study published in the journal Cell Stem Cell, reveals how different types of cells in the bone marrow are responsible for supporting blood stem cell maintenance before and after injury. It was already well known in the field that two different cell types, namely endothelial cells (which line blood vessels) and stromal cells … Continue reading Support cells have different roles in blood stem cell maintenance before and after stress
Engineered bone tissue improves stem cell transplants
Bone marrow transplants are currently the only approved stem cell-based therapy in the United States. They involve replacing the hematopoietic, or blood-forming stem cells, found in the bone marrow with healthy stem cells to treat patients with cancers, immune diseases and blood disorders. For bone marrow transplants to succeed, patients must undergo radiation therapy to … Continue reading Engineered bone tissue improves stem cell transplants
A single protein can boost blood stem cell regeneration
Today, CIRM-funded scientists from the UCLA Broad Stem Cell Research Center reported in Nature Medicine that hematopoietic stem cells (HSCs) - blood stem cells that generate the cell in your blood and immune system - get a helping hand after injury from cells in the bone marrow called bone progenitor cells. By secreting a protein called dickkopf-1 … Continue reading A single protein can boost blood stem cell regeneration
Deleting a single gene can boost blood stem cell regeneration
A serious side effect that cancer patients undergoing chemotherapy experience is myelosuppression. That’s a big word for a process that involves the decreased production of the body’s immune cells from hematopoietic stem cells (HSCs) or blood stem cells in the bone marrow. Without these important cells that make up the immune system, patients are at … Continue reading Deleting a single gene can boost blood stem cell regeneration
UCSF study explains how chronic inflammation impairs blood stem cell function
Inflammation is the immune system’s natural protective response to infection and injury. It involves the activation and mobilization of immune cells that can kill off foreign invaders and help repair damaged tissue. At the heart of the inflammatory response are hematopoietic stem cells (HSCs). These are blood stem cells found in the bone marrow that … Continue reading UCSF study explains how chronic inflammation impairs blood stem cell function
