Keeping stem cells strong: RNA molecule protects stem cells during inflammation

A team of researchers led by biologists at the California Institute of Technology has found that, in mouse models, the molecule microRNA-146a acts as a critical regulator and protector of blood-forming stem cells (called hematopoietic stem cells, or HSCs) during chronic inflammation, suggesting that a deficiency of miR-146a may be one important cause of blood cancers and bone marrow failure.

Simi Valley boy meets Englishman who gave him life-saving transplant at City of Hope

Ryan Compton, 8, of Simi Valley, left, poses for a picture with his bone marrow donor, Barry Crackett, 34, from England, during the City of Hope’s reunion of cancer survivors meeting their lifesaving bone marrow donors for the first time event, at the City of Hope in Duarte, Friday, May 10, 2013.

Nerve Protecting Agents May Help Prevent Chemotherapy-Induced Anemia

Cancer chemotherapy can cause peripheral neuropathy – nerve damage often resulting in pain and muscle weakness in the arms and legs. Now, researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that chemo also induces an insidious type of nerve damage inside bone marrow that can cause delays in recovery after bone marrow transplantation…

Discovery may help prevent chemotherapy-induced anemia

Researchers have discovered that chemo induces a type of nerve damage inside bone marrow that can cause delays in recovery after bone marrow transplantation. The findings suggest that combining chemotherapy with nerve-protecting agents may prevent long-term bone marrow injury.

Potential drug targets, markers for leukemia risk identified

Investigators have detailed and broadly classified the genomic alterations that frequently underlie the development of acute myeloid leukemia (AML), a deadly cancer of the blood and bone marrow. Their work paints a picture of a cancer marked by relatively few mutations compared to other types of cancer occurring in adults.

TCGA researchers identify potential drug targets, markers for leukemia risk; New study reveals relatively few mutations in AML genomes

Investigators for The Cancer Genome Atlas (TCGA) Research Network have detailed and broadly classified the genomic alterations that frequently underlie the development of acute myeloid leukemia (AML), a deadly cancer of the blood and bone marrow. Their work paints a picture of a cancer marked by relatively few mutations compared to other types of cancer occurring in adults.

Clarifying the effect of stem cell therapy on cancer

Injection of human stem cells into mice with tumors slowed down tumor growth, finds new research. Human mesenchymal stem cells, isolated from bone marrow, caused changes in blood vessels supplying the tumor, and it is this modification of blood supply which seems to impact tumor growth.

Method makes it easier to separate useful stem cells from ‘problem’ ones for therapies

Pluripotent stem cells can turn (differentiate) into any cell type in the body, such as nerve, muscle or bone, but inevitably some of these stem cells fail to differentiate and end up mixed in with their newly differentiated daughter cells. Scientists have discovered a new agent that may be useful in strategies to kill off pluripotent stem cells from differentiated daughter cells.
