Bodyguard macrophages protect stem cells from over-differentiation

Hiding deep inside the bone marrow are special cells. They wait patiently for the hour of need, at which point these blood forming stem cells can proliferate and differentiate into billions of mature blood immune cells to help the body cope with infection, for example, or extra red blood cells for low oxygen levels at high altitudes. Even in emergencies, however, the body keeps to a long-term plan: It maintains a reserve of undifferentiated stem cells for future needs and crises.

Research roundup: Financial impact of reducing surgical complications; Pay for performance to doctors, hospitals yields mixed results

The authors write: "We found that if a hospital's surgical inpatient volume is not growing, such a program results in negative cash flow. We also found that if a hospital's surgical volume is growing, and if the hospital can sufficiently reduce the average length-of-stay for surgical patients without complications, the cash flow could be positive. We recommend that hospitals with limited growth prospects that are nonetheless contemplating a surgical complication reduction program establish agreements with payers to share in any savings generated by the program."
