Stem cell count and quality

In the talk linked below, Mark Katakowski talks about how our circulating stem cell count and quality declines with age. Jump to 17 minutes into the video.

Does anyone know of any testing facility that can measure the count and quality of stem cells from a sample of blood. 

Also does anyone know the original source of the study showing decline in stem cell count and quality with age. Thanks.
