MiRNA fingerprint identified in platelet formation

...ion. Platelets are created from stem cells in the bone marrow. They evolve through a process called megakaryocytopoiesis, which generates megakaryocytes, or platelet parent cells. The research team used microRNA gene chip analysis to identify miRNA expression in normal stem cells and megakaryoctyes. The...

Front-line immune cells mature in four stages, study shows

..., T cells and B cells, developed in the thymus and bone marrow, respectively. However, the site and stages of human NK cell development have eluded investigators until now. The findings advance the understanding of NK cells, which play a key role in triggering broader immune responses such as the body's...

Powerful technique for multiplying adult stem cells may aid therapies

...t offers tremendous promise for treatments such as bone marrow transplants and perhaps even gene therapy. ...e stem cells can be acquired either from a donor's bone marrow, or even from cord blood (donated cord blood, or the patient's own). Still, in both these cas...

Cell therapy slows progression of an inherited neurological disease; Improves motor skills in mice

... There is no cure; the only current treatment is a bone marrow transplant. Ernesto Bongarzone, PhD, and his colleagues at the San Raffaele Scientific Institute in Milan, Italy, transplanted cells that produce myelin into the brains of newborn MLD mice. The researchers found that the transplanted myelin-...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...." Using a library of antibodies derived from the bone marrow of two vaccinia-immunized chimpanzees, the study researchers identified a pair of potent antibodies that target and neutralize the B5 protein, one of five key proteins responsible for cell-to-cell spread of infectious vaccinia virus. The resea...

Marine mammals are on the frontline of failing ocean health

"The issue is to understand how pollutants are transferred through the ocean food web to consumers, both humans and animals," says Peggy Krahn of the NOAA. "Until ...

The findings add weight to two currently popular theories: that the crests were used to create resonant sounds to attract mates or warn of preda...
