Adipose-derived stem cell therapy | Lipoaspirate Prolotherapy | Fat Stem Cells

Stem Cell Therapy and Platelet Rich Plasma Therapy when to use both

Ross Hauser, MD

If you are reading this article you are likely looking for the answers to two questions. The first question is:

The second question is:

Lipoaspirate Prolotherapy or  Adipose-derived stem cell therapy is a regenerative injection treatment that stimulates repair of osteoarthritic cartilage and bone through the use of liposuction aspirates (fat stem cells).

Adipose-derived stem cell therapy to treat chronic pain

While bone marrow has historically been used as a source of stem cells, adipose (fat)-derived stem/stromal cells (stromal cells are connective tissue cells) have been shown to have:

Autologous bone marrow stem cell volume is limited, but adipose tissue represents a large reservoir of stem cells. Research also supports as much as 500 to 1000 times as many mesenchymal and stromal vascular stem-like cells in adipose as compared to bone marrow. However, as research below indicates, the number of stem cells is not always predicate a positive healing treatment.

In 2011, researchers in Finland published  their research suggesting the benefits of Adipose stem cells, here are the take home points of that research published in the journal Stem Cell Reviews:

Adipose-derived stem cell therapy techniques in treating chronic pain

As mentioned above, a patient researching fat stem cell injections will often ask “what’s the difference between your treatments and another type of fat stem cell treatment?” This is a difficult question to answer because we do not do all the other methods, we do our method of fat stem cell treatment that has evolved and been refined over decades.

A better question to ask may be:

“How long has your office offered stem cell therapy?”, “How many patients have you seen?”

All this experience has taught us that Prolotherapy should be involved in stem cell therapy. There are times when bone marrow serves a better purpose than fat stem cells and each patient presents a unique circumstance and stem cell therapy must remain flexible and adaptable to give the patient the best chance of achieving their goals of treatment.

Treating the whole joint to give Adipose-derived stem cell therapy its best chance of healing success

We will discuss at length the research that supports the use of Platelet Rich Plasma and Prolotherapy in support and augmentative procedures in fat stem cell treatments. Briefly:

Treatment with Prolotherapy concurrent with stem cell treatment addresses the problem that the stem cell treatment may not. That is the repair of the joint instability which caused the osteoarthritis is the first place.

Whole joint Lipoaspirate Prolotherapy | Same-day fat stem cell therapy

Whole joint Lipoaspirate Prolotherapy treatment begins with collected fat stem cells. Lipoaspirates are obtained from the abdomen or love handle area through a quick liposuction procedure. The gentle liposuction takes a few minutes, and the whole time in the office is an estimated 60-90 minutes.

Lipoaspirate Prolotherapy is generally used in more severe cases of joint deterioration where a very strong proliferant solution may be a factor in speeding up the healing response. The main reason to use lipoaspirates as the proliferant in Prolotherapy is that adipose (fat) tissue contains an abundant population of stem cells.

Stem cells are self-renewing cells in our bodies which repair and replace old/damaged cells. Injecting these cells directly into the damaged tissue has been shown to enhance the integrity of the tissue and reduce pain.

Direct injection of fat stem cells 

In reviewing the cumulative research of both animal and human studies, doctors at the Rizzoli Orthopaedic Institute in Italy, publishing in the journal Stem Cell International, found injection of adipose-derived mesenchymal stem cell was first, safe and effective, and that secondly several aspects favor the use of freshly harvested adipose-derived mesenchymal stem cell instead of expanded or cultured adipose-derived mesenchymal stem cell.

Let’s explore this research a little further. The researchers looked at 11 clinical studies. In these studies the application of fat stem cells into the knee was performed in many different ways including during arthroscopic knee procedures. This is what they found:

All clinical studies showed that adipose-derived stem cells improves pain and functional scores at a follow-up of between 3 and 36 months.2

In three studies MRI analysis was performed, which revealed improved features, including increased cartilage thickness.

What does all this mean? Cultured vs. non-cultured cells? Number of stem cells needed for treatment?

What we have above is many different methods of delivering adipose-derived stem cells. All with varying degrees of success. However, the  Italian research team noted that despite all the new data arising from these studies, the key concerns, such as the best amount of cells and the ideal scaffold (a scaffold in a medium that the stem cells can grow in) to be used, still remain unsolved.

In cultured adipose-derived mesenchymal stem cell treatment, the fat cells are cultured and grown outside the body. In research from the University of Pittsburgh the doctors found: “the use of cultured cells allows researchers to isolate and better characterize the desired cell type; however, economic and regulatory issues favor minimal manipulation procedures in the clinical practice.” 3 Other research suggests the opposite that culturing cells and the number of stem cells injected are a major focal point of the treatment.

In some instances of joint disease, doctors find that they want to expand the number of stem cells to create an accelerated healing environment. There is research to support this. There is also research to support that same day – non-cultured stem cell injections are just as effective and more importantly to the patient, provides a more simplified, less expensive, and as effective treatment.

The debate of course will continue.

In 2017, doctors writing in the Journal of biomedical science, gave this explanatory summary:

Due to the current regulatory environment, culture expanded stem cells are considered to be a pharmaceutical product and require governmental clearance and approval. Autologous adipose SVF injection, on the other hand, is considered to be a medical procedure, and thus allowed in many parts of the world.

Consequently, autologous adipose SVF is slowly being tried as an alternative treatment in the field of orthopedics, treating disorders involving cartilage, bone, and tendons/ligaments. Compared to bone marrow SVF, adipose tissue is considered to be a preferred source of MSCs in the form of SVF due to its ease of accessibility and the availability of a large number of stem cells per gram of adipose tissue.

Although numerous studies available that show the effectiveness of fat stem cell treatment in osteoarthritis patients, the comparison of these studies show lack of standardization. Lacking standardization may lead to differences in results of the treatment.

It seems the amount of autologous adipose tissue used in producing adipose stem cells has no direct relationship with the efficacy and safety observed. Some of the studies used only 20 g of adipose tissue while others have used more than 100 g of adipose tissue. One study showed in a double-blind randomized clinical trial that higher number of stem cells may result in improved cartilage regeneration.5

Research examines the beneficial effects of Platelet Rich Plasma on adipose-derived mesenchymal stem cells.

Here is what Japanese researchers found in their published data in the journal Stem Cell Therapy and Research:

Platelet-rich plasma (PRP), which contains high levels of diverse growth factors that can stimulate stem cell proliferation and cell differentiation in the context of tissue regeneration, thus the co-transplantation of adipose-derived mesenchymal stem cells and PRP represents a promising novel approach for cell therapy in regenerative medicine and a promising approach in various fields of medicine and dentistry.6

Combining stems cells with Platelet Rich Plasma Therapy as a means to accelerate tissue regeneration in advanced degeneration has been the subject of numerous animal and human studies. 7,8,9

All the healing elements in the body to travel through the blood, so using blood as a delivery vehicle makes sense

Platelet Rich Plasma has the ability to both increase stem cells and guide them in healing. In initial findings, PRP assisted stem cells in “figuring out” what they needed to be – whether a cartilage cell, or a bone cell, or a collagen cell for ligaments and tendons.

So the platelets are already attuned to provide a healing environment or scaffold to build on. In the research cited below results confirmed that PRP enhances MSC stem cell proliferation and suggested that PRP causes chondrogenic differentiation of MSC in vitro – in other words, the platelets told the stem cells what to do.

The platelets themselves secrete a variety of cytokines (proteins that regulate various inflammatory responses), including adhesive proteins and growth factors such as platelet-derived growth factor, transforming growth factor beta, vascular endothelial growth factor, basic fibroblast growth factor, Insulin-like growth factor-1 (IGF-1), and epidermal growth factor. All the healing elements in the body to travel through the blood, so using blood as a delivery vehicle makes sense.

Prolotherapy, PRP, and Adipose-derived stem cell therapy used in combination

Lipoaspirate & PRPIn our experience, where the Prolotherapy injections are given is also an important factor, not just what is injected. This means that Stem Cell Therapy or Stem Cell Prolotherapy at Caring Medical includes not just a couple injections of stem cell proliferants, but additionally, the whole joint/painful area is treated for underlying instability, which is likely the cause of the injury in the first place. If this aspect of the patient’s condition is not treated, we find that complete healing may not occur.

The treated area is typically stiff and swollen after the treatment, because the desired effect is a temporary, localized inflammation to stimulate blood flow and growth factors in the area. A patient can return to work the same or next day. Our practitioners will help athletes return to exercise, generally within the week, and discuss possible modifications to encourage healing and minimize discomfort. The average number of treatments needed to achieve full healing is four to six, and each treatment is given four to eight weeks apart.

Like all medical conditions and therapies, each person responds individually. At the initial visit, your Prolotherapy specialist discusses how many treatments he or she feels will be needed to achieve the patient’s goals. An experienced Prolotherapy physician can give a reasonably accurate estimate. Because we see a lot of tough cases in our clinic who have failed numerous other treatments, sometimes it might be known upfront that Prolotherapy treatments could be needed for a full year or longer. Though this is rare, for a patient who is adamantly against surgery, or who has already failed surgeries, he or she may consider the time, energy, and money to use Stem Cell Prolotherapy worthwhile.

The first step is simple: Come in for a consultation. This way you will know what is the right Prolotherapy solution for you! At our offices, we utilize many individualized solutions, and would love to help you.
