how to improve stem cells

I get asked almost on a daily basis how to improve stem cells by patients who are contemplating a stem cell injection. While many things are important such as diet, exercise, and supplements, does a little known blood marker associated with heart attacks make a difference? What is homocysteine and why does it matter when it comes to stem cells?

While cholesterol has gotten a lot of attention with regard to heart disease (mostly due to big pharma), homocysteine has become the red headed stepchild of cardiac risk. Homocysteine is an amino acid that ‘s a cousin of the more common cysteine, an essential building block of protein. In fact, it can be converted into cysteine through B vitamins. High levels of homocysteine has been linked to cardiovascular disease because it makes a person more prone to endothelial injury, which leads to vascular inflammation. This is how plaques get formed which can rupture and cause heart attacks.

While high levels of homocysteine are linked to poor cardiovascular health, are there implications for your stem cells? A recent lab study is concerning. The researchers exposed bone marrow mesenchymal stem cells to homocysteine, simulating the high levels present in some patients. This exposure moved the stem cells toward pre-programmed cell death (apoptosis).

Are there ways to get your homocysteine levels down and improve your stem cells? First, get your levels measured, as most family doctors overlook this important heart health bio marker. Second, if they’re high, there’s nothing like good old exercise! A recent study looked at the effects of 28 days of regular exercise on endothelial progenitor cells (EPCs or stem cells that repair damaged blood vessels) and homocysteine levels. They found that regular exercise training could increase the number of EPCs and decrease homocysteine levels, thus decreasing cardiovascular disease risk in men.

Another tried and true way to get homocysteine levels down is good old B vitamins. If you’re on a low carb or paleo diet, there’s a reduction in the amount of breads and wheat consumed. While this is great to control blood sugar and lose weight, bread is an important source of B vitamins. Can supplementing with a B complex help? A recent large study of about 120,000 men and women in two large study groups found that men who supplemented with vitamin B (and not women) had lower homocysteine levels and less peripheral artery disease.

The upshot? If you’re trying to learn how to improve stem cells, pay attention to the red headed step child of cardiac risk markers – homocysteine. To improve this metric, simply exercise regularly or if you’re male, take your B complex vitamins!

Regenerative procedures are commonly used to treat musculoskelatal trauma, overuse injuries, and degenerative issues, including failed surgeries.
Select Your Problem Area
Shoulder

Shoulder

Many Shoulder and Rotator Cuff injuries are good candidates for regenerative treatments. Before considering shoulder arthroscopy or shoulder replacement, consider an evaluation of your condition with a regenerative treatment specialist.

  • Rotator Cuff Tears and Tendinitis
  • Shoulder Instability
  • SLAP Tear / Labral Tears
  • Shoulder Arthritis
  • Other Degenerative Conditions & Overuse Injuries

Cervical Spine

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.

  • Herniated, Bulging, Protruding Discs
  • Degenerative Disc Disease
  • SI Joint Syndrome
  • Sciatica
  • Pinched Nerves and General Back Pain
  • And more

Knee

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
  • Knee Osteoarthritis
  • Other Knee Ligaments / Tendons & Overuse Injuries
  • And more

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.

Hand & Wrist

Hand & Wrist

Hand and wrist injuries and arthritis, carpal tunnel syndrome, and conditions relating to overuse of the thumb, are good candidates for regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
  • Hand and Wrist Arthritis
  • Carpal Tunnel Syndrome
  • Trigger Finger
  • Thumb Arthritis (Basal Joint, CMC, Gamer’s Thumb, Texting Thumb)
  • Other conditions that cause pain

Elbow

Elbow

Most injuries of the elbow’s tendons and ligaments, as well as arthritis, can be treated non-surgically with regenerative procedures.

  • Golfer’s elbow & Tennis elbow
  • Arthritis
  • Ulnar collateral ligament wear (common in baseball pitchers)
  • And more

Hip

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 & 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.
  • Ankle Arthritis
  • Plantar fasciitis
  • Ligament sprains or tears
  • Other conditions that cause pain
