“Adaptive resizing of the intestine makes sense from the standpoint of physiological fitness. Upkeep of the intestinal lining is metabolically expensive, consuming up to 30 percent of the body’s energy resources. By minimizing intestinal size when food is scarce, and maximizing digestive capacity when food is abundant, adaptive intestinal resizing by stem cells helps animals survive in constantly changing environments.”--UC Berkeley post-doctoral fellow Lucy O’Brien.( |, D& N& i4 H3 J9 _
! C' ^6 }$ B7 P( B“If this research transfers successfully to clinical application in humans, we could establish personal stem cell banks. We would collect a small number of older stem cells from patients, put those into our young microenvironment to rescue them — increasing their number and quality — then deliver them back into the patient.”-- XiaoDong Chen, M.D., Ph.D., a stem cell researcher at the UT Health Science Center.6 O+ i2 H% o) K4 r

“Virtually everything else is highly experimental. On one hand there are charlatans selling snake oil. At the other end of the spectrum are physicians who may be well-intentioned, but they’re misinformed if they’re giving patients stem cells before they’ve been proven to work.”--George Daley, the director of stem cell transplantation at Children’s Hospital Boston." _9 F4 |7 t0 j

“There is always a possibility that you can introduce infection when you inject a joint, so sterile technique must be used. But I’ve injected more than 900 joints, and I haven’t had one infection. We don’t expect a lot of adverse events with stem cells.”--Mike Hutchinson, DVM, owner of Animal General of Cranberry.% O6 [0 n/ J4 q' n
