Very ingenious idea! Kudos for starting an entire company like that. As a layman, I do wonder what the difference is in cell quality when they're extracted at age 20 / 40 / 60 / 80. Do the MSCs deteriorate, which is why it is beneficial to freeze them?
Yes, they do. They decrease in both number and in function (as measured by their ability to divide, and form new tissue, such as bone). Here are some various references: http://www.ncbi.nlm.nih.gov/pubmed/26088863 http://www.ncbi.nlm.nih.gov/pubmed/24607555 http://www.ncbi.nlm.nih.gov/pubmed/25634304 http://www.ncbi.nlm.nih.gov/pubmed/25096220 So when you are most likely to suffer from diseases these cells might treat, your own cells have loss much of their therapeutic potential. One study that I found particularly interesting was that the number of circulating progenitor cells (cells expressing a stem cell marker) in octogenarians was predictive of longevity:
