Environmental Factors Instruct Lineage Choice Of Blood Progenitor Cells
The research team led by Dr. Timm Schroeder, stem cell researcher at Helmholtz Zentrum MÃønchen, has developed a new bioimaging method for observing the differentiation of hematopoietic progenitor cells (HPC) at the single-cell level. With this method the researchers were able to prove for the first time that not only cell-intrinsic mechanisms, but also external environmental factors such as growth factors can control HPC lineage choice directly. The findings, published in the current issue of the prestigious journal Science, provide an essential building block for understanding the molecular mechanisms of hematopoiesis and are an important prerequisite for optimizing therapeutic stem cell applications.

What Is Shingles? What Causes Shingles?
severity of shingles. Experts recommend that people over 60 have this vaccine, regardless of whether or not they have had shingles before. The vaccine is preventative, and is not used to treat people who are infected. The following people should not have the shingles vaccine: *Those who have had a life-threatening reaction to gelatin, neomycin (an antibiotic), or any other shingles vaccine component. *People who have a weakened immune system *Patients receiving steroids, radiotherapy, and/or chemotherapy *Patients with a history of bone marrow or lymphatic cancer *Patients with active, untreated TB (tuberculosis) Doctors say people with a mild cold may take the vaccine, but not those who are moderately or severely ill (they should wait till they are recovered).
