The Promise of Regenerative Medicine

Current regenerative medicine strategies excite me for a couple of key reasons. For starters, these therapies are largely directed at treating the underlying cause of a disease rather than the end consequence. The idea is to cure the problem instead of endlessly managing a chronic condition. I went into neurosurgery because I absolutely love performing the highest level of surgeries—none of them vanity-based, and few of them elective. These surgeries are often lifesaving and, in most cases, life-changing, so for me, I’m deeply rewarded and grateful to have this gift. But wouldn’t it be nice to cure the underlying problem at the same time?

Another aspect of regenerative medicine strategies that excites me is that they are generally directed at the cellular level of the disease. Cells throughout our bodies share similar properties in the ways they stay alive and healthy, meaning that any given treatment could potentially target every cell in the body. Even better, these cellular treatments are natural and often autologous—meaning they use cells and tissues from your own body. That’s right, all-natural. This means no big pharma, no hospitals, and whether good or bad, no insurance coverage (each of these realizations could be their own blog entry, but suffice it to say that these treatments do not fit the business plan of traditional medicine!).

Here’s an example that may resonate with you. Assume, for the purposes of discussion, that you have a hypothetical orthopedic or spine issue, and your doctor orders an MRI. After weeks or months of rest, medications, and physical therapy, you still haven’t returned to your regular activities. The MRI shows a joint or spine issue, and you are referred to a specialist who diagnoses the problem and recommends surgery. Let’s assume you don’t want to have surgery just yet and ask for other options. It is typical for the specialist to offer you a steroid injection “to get you by.”

Steroid treatment may help relieve pain from acute inflammation, but it will do nothing to heal your problem. It’s barely a band-aid, and in fact, repeated use of steroids can be damaging to tissues. It is highly unlikely that you will avoid the surgery you’re trying to avoid by getting steroid injections. On the contrary, there are potential regenerative injections you could use instead of steroids that have healing properties. Let me give you an example that I have used myself—platelet-rich plasma (PRP).

Platelets (thrombocytes) are small, disc-shaped cell fragments in the blood that play a crucial role in blood clotting and wound healing. They don’t have a nucleus, but they contain several essential components, including growth factors and enzymes that enable them to perform their functions.

Platelet-Rich Plasma (PRP) therapy uses your own blood to support healing and tissue regeneration, including cartilage repair. The idea is to harness the natural growth factors in platelets to stimulate cell growth, tissue repair, and anti-inflammatory effects. Here’s how PRP helps in cartilage healing:

High Concentration of Growth Factors: PRP is created by drawing a small amount of the patient’s blood, then separating and concentrating the platelets. These platelets contain growth factors and proteins that promote tissue repair and healing, such as transforming growth factor-beta (TGF-β), platelet-derived growth factor (PDGF), and vascular endothelial growth factor (VEGF). When injected into a damaged cartilage area, these growth factors encourage cartilage cells (chondrocytes) to proliferate and synthesize new cartilage matrix.
Enhanced Collagen Production: PRP helps stimulate the production of collagen, a key structural protein in cartilage. Collagen provides strength and elasticity, which are essential for cartilage function and its ability to withstand compression.
Reduction of Inflammation: Cartilage damage often involves inflammation, which can worsen the injury. PRP has anti-inflammatory properties that help reduce this inflammation, creating a more favorable environment for healing and minimizing further cartilage degradation.
Stem Cell Activation: Some studies suggest that PRP may stimulate the body’s mesenchymal stem cells (MSCs) to differentiate into chondrocytes, the cells responsible for producing cartilage. This differentiation can potentially contribute to the regeneration of cartilage tissue.
Improved Blood Flow: The growth factors in PRP also promote angiogenesis, or new blood vessel formation, which helps bring more nutrients and oxygen to the damaged area. Although cartilage itself is not highly vascularized, improved blood flow to surrounding tissues can support the healing process.

While promising, it’s worth noting that PRP’s effects on cartilage healing are still being researched, and results can vary. PRP may be more effective for early-stage cartilage damage rather than severe degeneration, and it is often used in conjunction with other therapies for optimal outcomes. In my opinion, without question, PRP offers some potential advantages over steroid injections:

1. Natural Healing vs. Inflammation Reduction

PRP: PRP therapy uses the patient’s own blood, processed to concentrate platelets, which contain growth factors that aid in tissue repair and healing. This stimulates natural healing rather than merely reducing symptoms.
Steroids: Steroid injections work primarily by reducing inflammation, which can relieve pain temporarily but doesn’t necessarily promote long-term healing of the damaged tissue.

2. Fewer Side Effects and Risks

PRP: Since PRP is derived from your own blood, the risk of adverse reactions is low, and there are fewer side effects. There’s a lower risk of complications, such as tissue weakening, which can sometimes result from repeated steroid use.
Steroids: Steroids may have side effects, especially with repeated use, including tissue damage, weakened tendons, skin thinning, and, in some cases, negative effects on blood sugar levels.

3. Potential for Longer-Lasting Relief

PRP: PRP may provide longer-lasting relief by addressing the underlying tissue damage, making it potentially more effective over time for chronic issues like tendinopathy or joint degeneration.
Steroids: Steroid injections can provide quick pain relief but often require repeated treatments since they focus on inflammation control rather than healing. Over time, the effect of steroids may diminish.

4. Lower Risk of Cartilage Damage

PRP: PRP is often used in joint treatments (e.g., for osteoarthritis) because it can aid in slowing the progression of cartilage degeneration and may even stimulate tissue repair.
Steroids: Prolonged or repeated steroid injections in joints may accelerate cartilage damage, particularly with conditions like osteoarthritis, potentially worsening the joint over time.

5. Applications in Orthopedics and Spine

PRP: PRP is used for muscle injuries, ligament sprains, joint injuries, or tendon injuries, as it can help promote faster recovery and reduce downtime while avoiding the risk of adverse effects linked to steroids.
Steroids: Steroids can delay healing if used in the early stages of an acute injury, so they are not always ideal for promoting recovery in sports-related injuries.

Drawbacks of PRP

PRP typically takes longer to show effects, with patients often noticing gradual improvement over weeks or months. In contrast, steroids offer more immediate relief.

In summary, while steroids offer quick relief from inflammation and pain, PRP offers a regenerative approach that may support long-term healing with fewer side effects.

PRP is just one of many natural regenerative treatment options that may not only help you with your pain symptoms but also repair the underlying problem that is the cause of your symptoms. Sooner than later, you may learn of other regenerative treatments that are outside the mainstream, but potentially highly effective.
