While we primarily focus on stem cells, another exciting tool in the regenerative medicine bucket is platelet-rich plasma (PRP). PRP is defined as concentrated platelets in plasma. But what does PRP do and what can it be used to treat?

The Healing Properties of Platelets

To understand how PRP works, we first need to understand what platelets do in the body. Platelets are very small cells found in the blood stream of mammals and are best known for their ability to clot the blood. However, there is much more that these tiny but powerful cells can do. A complex signaling system sent out from damaged cells attracts platelets to an injury and tells them to release several healing molecules that they have stored inside of them. In turn, these healing molecules attract a multitude of additional healing cells (including stem cells) to the site of injury or inflammation. Together, these cells have been shown to reduce pain, remove the damaged cells, build new blood vessels, prevent further tissue damage, and generate new healthy cells in place of the injured ones.

What can PRP be Used to Treat?

In veterinary medicine, PRP is most often used for orthopedic problems such as cruciate ligament tears, osteoarthritis, and tendon injuries in dogs, cats, and horses. However, recent research has shown that PRP can also aid in the healing of skin wounds, corneal (eye) ulcers, surgical incision sites, tooth sockets following extraction, and even muscle tears. Platelet therapy can also be used in conjunction with VetStem Cell Therapy to maximize the effect of both treatments.

PRP Kits: How they Work and the Associated Disadvantages

Historically, PRP has been produced using the patient’s blood. The blood is run through a mechanical device, or kit, each of which requires a unique processing method. The end result is concentrated platelets in plasma (PRP), however the exact concentration of platelets in the final product is not usually known.

This is perhaps the biggest disadvantage when using kits to produce PRP. There are several variables that can affect the final platelet concentration such as the current health of the patient, platelet count of the patient, operator handling of the sample, and the effectiveness of the kit used to produce the PRP. In a recent comparison of four PRP kits for the production of equine PRP, these kits demonstrated a lack of uniformity relating to the final platelet count and platelet concentration, and each kit failed to meet their respective platelet concentration claim.

Consistency is Key: PrecisePRP™

Fortunately, VetStem found a way to significantly reduce these disadvantages. PrecisePRP™ is a freeze-dried, donor-derived platelet-rich plasma; truly an off-the-shelf PRP. Each vial of PrecisePRP™ is uniform in platelet characteristics and concentration. This eliminates the variability mentioned above so that veterinarians know exactly what they’re injecting every single time, which can increase positive treatment outcomes. Additionally, PrecisePRP™ is not a kit and does not require processing, making it an easy and convenient alternative to currently available PRP kits.

We took the development of this product very seriously to ensure a positive safety profile. All donors are screened according to the FDA CVM guidance 254. Each batch is sterility, endotoxin, and quality tested to meet precise product release specifications. In controlled safety studies of dogs and horses, there were no notable adverse events related to treatment with PrecisePRP™. This unique product is currently available in both dog and horse formats.

A sad story that we hear a lot is when a ball-loving dog is no longer able to play fetch due to arthritis or some other orthopedic injury. That was the case for Sherlock, a nearly 100-pound Staffordshire terrier/rottweiler mix. Though Sherlock loved to chase his ball, as he got older, his body started slowing down and he was diagnosed with arthritis in all four limbs. In an effort to not take away his favorite activity, his owners continued to play ball with a little less intensity. And then he tore his cruciate ligament in his right knee.

Fortunately for Sherlock, his veterinarian recommended using VetStem Cell Therapy in conjunction with surgery. Stem cells have the ability to reduce pain, inflammation, and minimize the formation of scar tissue. In addition to his injured knee, Sherlock’s veterinarian treated both of his elbows and his non-injured knee to give him some relief from the arthritis in those joints.

Sherlock’s owner reported that he responded well to his initial stem cell treatment but that shortly after, he injured the cruciate ligament in his left knee. Unfortunately, this is more common than you may think. According to the American College of Veterinary Surgeons, 40-60% of dogs who injure one cruciate ligament will go on to injure the other cruciate ligament in the future. This time, Sherlock’s veterinarian was able to request doses from his stored stem cells, which she administered during the surgery on his left knee. Sherlock once again received an injection of his own stem cells into each knee and each elbow.

After treatment, his owner said that his recovery went from six weeks to three-and-a-half weeks. She stated, “He healed so quickly that it surprised everyone. He was 12 years old by this time and a full recovery seemed almost too hopeful to wish for, but instead we not only got a full recovery but a faster recovery than before.” She went on to state, “Sherlock is now 13 years old and we do not run and chase balls anymore, but we enjoy walks on the beach and lots of snuggles and I am so grateful that he is still here feeling good and enjoying life with me. Stem cell therapy made an immense difference in his ability to live a high quality life in his older years.”

VetStem founder and CEO, Dr. Bob Harman, recently joined Fuzzybutts and Friends on a podcast to discuss VetStem Cell Therapy and the science of stem cells. Joining him is Dr. Angie Zinkus, veterinarian and VetStem enthusiast at Germantown Parkway Animal Hospital. This podcast really gets down to the nitty gritty about stem cells and the various diseases that have been treated with VetStem Cell Therapy. Some of the big questions that are addressed are:

What are stem cells? Where do they come from? What are the mechanisms of action/how do they work? What CAN’T be treated with stem cells? And more!! You don’t want to miss this one!

All of us have heard the term “stem cells” and most of us have some basic understanding of what that means. Stem cells are often referred to as the building blocks of life. Thus, when it comes to stem cells, many people think of embryonic stem cells. But when we talk about VetStem Cell Therapy, we’re actually talking about adult stem cells.

Adult Stem Cells vs. Embryonic Stem Cells

There are several differences between embryonic and adult stem cells. Embryonic stem cells serve one purpose: to form whole organs and organisms. They are truly the “building blocks of life.” Embryonic stem cells exist only at the earliest stages of development, and they are pluripotent, meaning they can differentiate into any cell type.

Adult stem cells on the other hand include multiple types of stem cells that are present in almost all tissues of the adult body. They can be multipotent or unipotent, meaning they can only differentiate into one type of cell. Mesenchymal stem cells (MSCs) are multipotent adult stem cells that have demonstrated the ability to differentiate into multiple cell types including tendon, ligament, bone, cartilage, cardiac, nerve, muscle, blood vessels, fat, and liver tissue.

Adult Stem Cells Mechanisms of Action

Adult stem cells are utilized by the body to replenish dying cells and to repair damaged tissues. This discovery led to multiple studies to help determine the full therapeutic benefits of adult stem cells. VetStem uses adult MSCs in an effort to repair damaged tissues in animals with various injuries and diseases. But this is not the only mechanism of action that stem cells utilize in the healing process. Stem cells have also been shown to down-regulate inflammation, reduce pain, and modulate the immune system. All of these mechanisms, and more that we’re still learning about, make stem cell therapy a multimodal approach to healing.

Ideal Source of Adult Stem Cells

When used for VetStem Cell Therapy, adult MSCs are extracted from fat tissue, one of the richest sources of MSCs in the body. Fat tissue is also relatively easy to collect during a simple anesthetic procedure similar to a spay. Most animals recover quickly and uneventfully from the procedure, compared to more painful and invasive stem cell collection techniques. Additionally, fat is generally abundant in the body, even in skinny animals, making it an ideal source of stem cells.
