Stem cell follow-up - I don't know how well your spoken English is (your written English is good) but there will be a meeting of the American Association of Orthopedic Medicine in early May, https://na.eventscloud.com/website/35031/agenda/, that includes discussion of specific treatments for the spine, albeit Lumbar. For previous meetings, AAOM has offered videos of their talks for purchase sometime after the meeting completes. I don't know if that would help you but it's a source of knowledge. I will admit that a review of the talks being given sounds like they're summarizing stuff we've discussed with our prolotherapists over the past decade and a half, so I have some reason to believe that the information presented at AAOM will be a long way away from cutting edge.
