Study: Megakaryocytes play an important role in cell migration

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red blood cells, platelets, and white blood cells.

Mathematical model helps quantify metastatic cell behavior

Cancer metastasis is a difficult stage to battle, especially if cancer cells are proliferating at a rapid pace. A new study reveals that metastatic cells change their shape to spread to other parts of the body. Researchers formulated a mathematical model to study metastatic cell behavior and similar cellular systems.

Postmenopausal women may be healthier if more pear-shaped than apple-shaped

Apple-shaped women are three times more likely to have a heart attack or stroke while being pear-shaped in postmenopausal years cuts the risk by almost half, a new study found.

Postmenopausal women who are "apple" shaped have greater risk of heart problems

Postmenopausal women who are "apple" shaped rather than "pear" shaped are at greater risk of heart and blood vessel problems, even if they have a normal, healthy body mass index according to new research.

Investigational drug for treatment of sickle cell disease shows early promise in clinical trials

An investigational drug for the treatment of sickle cell disease is showing early promise in clinical trials for impacting biomarkers of the disease in patients, reported UConn School of Medicine researchers at the European Hematology Association Congress in Amsterdam this week.

Scientists pinpoint cause of fatal respiratory disorder that turns babies' lips and skin blue

Scientists used a gene editing method called CRISPR/Cas9 to generate mice that faithfully mimic a fatal respiratory disorder in newborn infants that turns their lips and skin blue. The new laboratory model allowed researchers to pinpoint the ailment's cause and develop a potential and desperately needed nanoparticle-based treatment.
