If there’s one single image that universally connotes death, it’s that of a skeleton. But in the living human body, bones are a beehive of activity that, at the cellular level, is as lively and intricate as any dance troupe could perform.
Within the hollows of the long bones dwells a spongy tissue called marrow, which hosts stem cells responsible for the production of both red and a variety of white blood cells. The latter are the warriors, messengers, sentries and medics that compose our immune system. White blood cells defend against microbial invaders and scour our bodies for suspicious

Here’s a story about life that begins on the No. 2 toe — the one next to the big toe — on the right foot of Jasmina Anema. In early January, a red blip, the size of a bug bite, appeared. It got itchy, and she told her mom, Thea Anema.
“It looked like nothing,” the mother said. Then the foot started to swell. On the morning of Jan. 20, on their way to Jasmina’s kindergarten at Public School 141 in Greenwich Village, they stopped at the pediatrician’s office.
Her abdomen was swollen; a test found
Researchers have discovered that umbilical cord stem cells, found in the blood of the umbilical cord, and able to differentiate into various types of tissue, represent a valid treatment alternative for leukemia patients that cannot find a compatible donor for a bone marrow transplant. American hematologists meeting in San Francisco for the 50th American Society of Hematology (ASH) Congress are now focusing their research on these types of stem cells to fight blood borne tumors.
An American study has recently called attention to the possible applications of umbilical cord stem cells for leukemia treatments. For years,
Transplanting own stem cells into heart of severe angina patients lessens their pain and improves their ability to walk, a new study has revealed.
The largest national stem cell study for heart disease showed that transplant subjects also experienced fewer deaths than those who didn’t receive stem cells.
In the 12-month Phase II, double-blind trial, subjects’ own purified stem cells, called CD34+ cells, were injected into their hearts in an effort to spur the growth of small blood vessels that make up the microcirculation of the heart muscle (…)
He also said that this study provides the first evidence that a person’s
TaiGen Biotechnology Co., Ltd. announced today that in a phase 1 study in healthy volunteers TG-0054, a chemokine receptor CXCR4 antagonist, was well tolerated and rapidly mobilized stem cells and endothelial progenitor cells from bone marrow into peripheral blood. The number of CD34+ stem cells in circulation after one dose of TG-0054 was equal or higher than reported cell numbers needed for stem cell transplantation in cancer patients. The observed AEs were all mild and transient. A phase 2 study in stem cell transplantation for multiple myeloma, non-Hodgkin lymphoma and Hodgkin disease patients is currently being initiated (…)
