A trial suggests a single infusion of stem cells may slow physical decline in older adults — but scientists disagree on why, or whether it works at all.
As people age, they become more vulnerable to a range of health problems, including frailty, which affects as many as 12 to 24 percent of older adults.
Frailty is a state of physical decline associated with low-level inflammation, muscle loss, and diminished physical capacity. It makes recovery from minor setbacks like falls harder and increases the risk of dementia and overall mortality.
