old age stem cells

Many patients ask about old age and stem cells. What happens to stem cells as we age? Is there an age limit to stem cell therapy? Let’s dig in.

Seminars on Stem Cell Therapy

A common sales pitch in many stem cell therapy seminars involves old age and stem cells. These clinics often claim that your stem cells are too old to use, hence you need to use young stem cells from umbilical cords. Is this true? To answer that question we need to first learn more about aging and stem cells.

What Happens to Stem Cells as We Age?

First, it’s important to note that you have millions of stem cells that live in your body (1,2). They are the repairmen of many tissues, so if you’re still alive, they are working. Meaning that wiping out the stem cells in your bone marrow would cause death in weeks to months (3).

Second, it’s been traditionally thought that stem cell number and health declines with age (4). However, our lab and others have looked at the number of stem cells in the bone marrow with aging. If you exclude really young people and just focus on adults, there isn’t a big relationship between stem cell number and age. This is shown in the slide below and based on data collected in our research lab (part of an upcoming research paper):

stem cells vs age

While this may look like Greek to you, the graphs show no relationship between stem cell numbers in the bone marrow and age.

Is There an Age Limit to Stem Cell Therapy?

One of the biggest questions I get on old age and stem cells is whether there is an age limit? I can answer that with some of our own published work. We looked at more than 800 patients with knee arthritis who had their own concentrated bone marrow stem cells injected into their joints versus age (5). We found no relationship between age and outcome, meaning older patients didn’t fare any worse than younger patients.

In a second study, what we did find that lead to poorer outcomes was too low a dose of total bone marrow cells (which is also tied to a low stem cell dose) (6). This could be easily overcome by a better bone marrow stem cell draw and processing. Meaning, older cells didn’t hamper someone’s chances of success, their cells just needed to be concentrated to a certain level.

We’re not the only ones to find this relationship between cell dose and outcome from stem cell-based procedures. In fact, others have found it when treating nonhealing bones and low back discs (12,13). Hence, getting stem cell therapy to work in older adults is about concentrating their cells.

Young Stem Cells?

As discussed above, a big sales pitch that you hear in stem cell therapy seminars is that your cells are just too old and you need younger stem cells from amniotic fluid or umbilical cords. As you’ve seen above, the first part of that sales pitch isn’t true. Now for the real shocker, neither is the second part. Meaning the amniotic and umbilical cord stem cell products being used by these clinics do not have live and viable stem cells. This has been confirmed by numerous university and third-party labs including Cornell and UC Irvine (7-9).

Now I can quote studies and show you graphs all day long, but a single picture says it all. The image below is from a joint study with our lab team and a university lab. What you’re seeing are the results of a stem cell test known as a CFU-f. Basically, stem cells show up as purple dots (colonies) here and when there is nothing but white, there were no stem cells found. On the left are five commonly used umbilical cord stem cell products (five wells of six white circles in a plate and one plate for each product). Notice that these plates are all white, hence all of these products used by these clinics had no live stem cells. The plates on the right with the purple dots representing real stem cell colonies represent bone marrow samples of elderly patients from their 50s to their 70s! There are plenty of stem cells in those tests.

old age stem cells

In summary, the young stem cell sales pitch is about as real as magic pixie dust. However, there are real stem cells in your own bone marrow, even if you’re in your 70s! Hence, if someone tries to sell you an amniotic or umbilical cord stem cell treatment because you’re too old, walk away.

The Other Downside of Umbilical Cord Cells

You may have recently heard that dozens of patients were made critically ill due to contaminated umbilical cord stem cells (11). Why? These products are not FDA approved like drugs and are not monitored in the same way (12). Hence, contamination in these products is more likely.

The upshot on old age and stem cells? While aging does have some impact on stem cells, it doesn’t mean you don’t have many live and very viable stem cells that can used to help you heal. In the meantime, as shown, stem cell seminar pitches claiming to inject you with millions of live stem cells don’t hold water!

    Does stem cell work on bone spurs? And can you use stem cell for the hip area if you have bone spurs in the hip and groin? Thanks. Ray

    1. Regenexx Team

      Hi Ray,
      We’d need to see the MRI images and get more information through the Candidacy review. Please see: https://regenexx.com/blog/removing-hip-bone-spurs-hip-impingement-no-better-nothing/ and https://regenexx.com/blog/hip-bone-spur-removal/ Bone spurs form as an attempt to stabilize an unstable joint so we treat these patients first by trying to remediate the biomechanical hip issues that caused the bone spur to form, and secondly by helping the joint cartilage remain healthier by injecting highly concentrated platelets or stem cells into the joint.

    I received a stem cell transplant to the lower lumber area of my back 2 years ago with close to 100% reduction in low back pain. Just over a week ago I received PRP injections to my SI joints bilaterally. While it is too early to know how effective the most recent treatment will be. I am hopeful of receiving significant pain relief to this area also. I will be celebrating my 77th birthday next month. My physician is part of the Regenex team.

Spine

Many spine injuries and degenerative conditions are good candidates for regenerative treatments and there are a number of studies showing promising results in treating a wide range of spine problems. Spine surgery should be a last resort for anyone, due to the cascade of negative effects it can have on the areas surrounding the surgery. And epidural steroid injections are problematic due to their long-term negative impact on bone density.

Knees

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

  • Knee Meniscus Tears
  • Knee ACL Tears
  • Knee Instability

Hip

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.

  • Labral Tear
  • Hip Arthritis
  • Hip Bursitis
  • Hip Sprain, Tendonitis or Inflammation
  • Hip Instability

Foot & Ankle

Foot and ankle injuries are common in athletes. These injuries can often benefit from non-surgical regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
