UCLA-led team creates first comprehensive map of human blood stem cell development

THIS BLOG IS ALSO AVAILABLE AS AN AUDIO CAST Human blood stem cells emerging from specialized endothelial cells in the wall of an embryonic aorta. UCLA scientists’ confirmation of this process clarifies a longstanding controversy about the stem cells’ cellular origin.

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

Breakthrough image could lead to better therapies

Image of a blood stem cell in its natural environment: Photo courtesy UC Merced When it comes to using stem cells for therapy you don’t just need to understand what kinds of cell to use, you also need to understand the environment that is best for them. Trying to get stem cells to grow in … Continue reading Breakthrough image could lead to better therapies

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 the key to speedy recovery after blood cancer treatment

Blood cancers, such as leukemia and lymphoma, are projected to be responsible for 10% of all new cancer diagnoses this year. These types of cancers are often treated by killing the patient’s bone marrow (the site of blood cell manufacturing), with a treatment called irradiation. While effective for ridding the body of cancerous cells, this … Continue reading Mechanical forces are the key to speedy 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

CIRM weekly stem cell roundup: stomach bacteria & cancer; vitamin C may block leukemia; stem cells bring down a 6’2″ 246lb football player

Stomach bacteria crank up stem cell renewal, may be link to gastric cancer (Todd Dubnicoff) The Centers for Disease Control and Prevention estimate that two-thirds of the world’s population is infected with H. pylori, a type of bacteria that thrives in the harsh acidic conditions of the stomach. Data accumulated over the past few decades … Continue reading CIRM weekly stem cell roundup: stomach bacteria & cancer; vitamin C may block leukemia; stem cells bring down a 6’2″ 246lb football player

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
