Bone Marrow News and Research

RSS

Bone Marrow is the soft, sponge-like tissue in the center of most bones. It produces white blood cells, red blood cells, and platelets.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers in a multi-institutional study led by Cincinnati Children's Hospital Medical Center slowed the growth of two particularly stubborn solid tumor cancers - neuroblastoma and peripheral nerve sheath tumors - without harming healthy tissues by inserting instructions to inhibit tissue growth into an engineered virus, according to study results published in the February 15 Cancer Research.

Yale procedure creates new bone tissue

A new technique that combines bone marrow removal and injection of a hormone helps promote rapid formation of new bone at targeted locations in the body, it was reported by Yale School of Medicine this month in Tissue Engineering.

Major milestone in the culturing of human blood stem cells

Patients with leukemia, certain autoimmune diseases and genetic defects such as sickle-cell anemia can be treated with blood stem cells either from a donor's bone marrow or from cord blood - but the supply of effective stem cells often runs short.

How a red blood cell loses its nucleus

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

New clues about how cancer cells grow

Scientists in Switzerland are uncovering new clues about how cancer cells grow - and how they can be killed - by studying stem cells, 'blank' cells that have the potential to develop into fully mature or 'differentiated' cells and other scientists in UK have made a breakthrough in understanding the cause of the most common form of childhood cancer, acute lymphoblastic leukaemia (ALL).

Researchers use embryonic stem cells to develop functioning immune system blood cells

For the first time, researchers have used embryonic stem cells to develop functioning immune system blood cells -- an important step in eventually using embryonic stem cells as an alternative source of cells for traditional bone marrow transplantations.

Discovery that embryonic stem cells can be used to create functional immune system blood cells

A new study demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells, a finding which is an important step in the utilization of embryonic stem cells as an alternative source of cells for bone marrow transplantation.

How red blood cells nuke their nuclei

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

Release of blood stem cells from bone marrow is regulated by brain through human biological clock

These new findings, published online on the website of the journal Nature, point out that the harvest of stem cells for transplantation may be improved by timing it at the peak of their release.

New cancer center at NewYork-Presbyterian/Weill Cornell

NewYork-Presbyterian Hospital/Weill Cornell Medical Center has created an expanded cancer program dedicated to advancing research, prevention and treatment of the disease. The new Cancer Center is led by renowned cancer physician-scientist Dr. Andrew Dannenberg.

Risk factors for severe RSV infection in immunocompromised children

St. Jude Children's Research Hospital investigators and collaborators have shown how to predict if a child who is infected with respiratory syncytial virus (RSV) while being treated for cancer or another catastrophic disease is at high risk for developing severe infection. The finding will help clinicians improve guidelines for managing these infected children.

New discoveries on what does and doesn't affect immune system

Scientists know that a number of factors can affect the body's immune system: poor diet, certain steroids, chronic stress. Now researchers at Michigan State University have discovered that an appetite-controlling hormone also affects the immune system, while natural versions of certain steroids do not.

Stem cell therapy studies for stroke, cerebral palsy prepare for clinical trials

Finding answers about optimal dosage and timing for stem cell therapy in adults with strokes and newborns with ischemic injuries is a goal of two new federally funded studies.

Kidney cancer drug attacks a major type of acute myeloid leukemia

A drug used to treat kidney cancer also targets a genetic mutation active in about one third of patients with acute myeloid leukemia (AML), the most common and lethal form of adult leukemia, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan. 29 edition of the Journal of the National Cancer Institute.

New nanomedicine research for prostate cancer

The Prostate Cancer Foundation, largely through the generosity of David H. Koch, has given $5 million to four institutions, including Weill Cornell Medical College, to support novel research in prostate cancer. The gift is one of the largest-ever individual donations for prostate cancer research.
