(Harvard Medical School) Researchers have developed a simple method for making a certain class of adult stem cells more therapeutically effective. By attaching a molecule called SLeX to the surface of human cells extracted from bone marrow, researchers have altered how the cells travel through vessels. This might enable the cells to more effectively reach sites of injury and replace damaged tissue.

Researchers from the Universities of Granada and León have shown that mononuclear blood cells from human umbilical cord can be an effective alternative to bone marrow. This work, to be published in the journal Cell Transplantation, could potentially mean a great advance in regenerative hepatic medicine.

It is widely believed that tumor angiogenesis and cancer growth critically depend on circulating endothelial precursor cells, mobilized from the bone marrow. A new study now suggests that a stem cell type supposed to be crucial for blood vessel formation and cancer growth does not actually exist.

Inflammation Triggers Cell Fusions That Could Protect Neurons, S...

Researchers discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells. This indicates that inhibitors of Notch may not affect bone marrow stem cells.

Gene Involved In Blood Stem Cell Replication, Movement, Identifi...

Researchers have identified a gene that is responsible for the division and movement of marrow-derived, blood-forming stem cells, a finding that could have major implications for the future of bone marrow and blood cell transplantation.

Watery Pools In Bone Marrow Key To Psoriatic Arthritic Damage
