Adipose Tissue – Mesenchymal Stem Cells (MSCs)
Harvesting Human Adipose Tissue Stem Cells – Mesenchymal Stem Cells (MSCs)
Adipose tissue is a medical term for cells that store fat. By harvesting some of the extra fat we have on our own bodies, concentrated adipose tissue can produce mesenchymal stem cells by a clinician removing the tissue, and then spinning it in a specialized centrifuge for harvesting stem cells. The process removes waste products and concentrates the mesenchymal stem cells (MSCs), for reinjection into the body. These stem cells then can perform their natural healing and tissue regeneration.
Researchers agree that adipose tissue is an abundant source of mesenchymal stem cells (MSCs), which can be used for tissue engineering. Lipo-aspirated MSCs may be a superior approach for some tissue-engineering purposes due to the ease in which harvesting of the MSCs occurs.[i]
Because of the unique ability of one’s own stem cells to perform tissue engineering, procedures are more commonly being performed for a variety of clinical procedures in the USA and around the world. Some of these include:
- Orthopedic Procedures & Regeneration
- Urological Surgery
- And more…
Recently Stanford University reported the efficacy of Stem Cells on stroke victims. In some of these patients, reversal of damaged brain tissue occurred. In June of 2016, Stanford declares stem cells as safe and beneficial for chronic stroke victims. A patient who lost movement in her right arm and leg, regained her movement after stem cells were injected into her brain.
The difficulty most non-medical professionals have in understanding stem cells is that they are a natural part of the body’s own healing process. Whenever we suffer an injury, our bodies were designed to heal themselves. As we age, and perhaps due to lifestyle, our healing capacity diminishes. The beauty of stem cell procedures is we can take our own healing stem cells, concentrate them, and reintroduce them to injury sites for more effective healing capacity.
Stem Cells are being used internationally on a wide-scale basis. The United States is falling dangerously behind due to regulatory issues. Because stem cells are natural, regulators have found it difficult in the USA to find a balance between limiting access to life-enhancing stem cell procedures, and access to care.

Stem Cell Quality – Adipose Stem Cells versus Bone Marrow
There is a common misconception within the medical community about which stem cell harvesting technique produces the highest quality and quality of stem cells most effective at regenerating injury for varying different tissue lineages. For instance, some physicians may recommend adipose derived stem cells for soft tissue injuries, while others recommend bone marrow derived stem cells for bone degeneration.
At face value this appears to be a logical decision. However, researchers are learning more everyday about how stem cells actually work and adapt based on a series of very complex molecular “medicinal-chemical” reactions in the body. In fact, in vitro and in vivo differences exist, so this makes it extremely important for researchers and clinicians alike to take into consideration not only the stem cells, but also the host environment of the patient where these stem cells are being introduced.
Stem cells, or more narrowly defined, mesenchymal stem cells, are really a combination of cells or molecules that produce chemical reactions based on the environment they are in. Essentially, more than just MSCs, are other molecules that also play key roles in the efficacy of a so called stem cell medicinal reaction-solution. These various molecules innately adapt and adjust as best they can in their natural way due to homing and the localized environment in which they are placed. MSCs tend to home and adapt to their environment, making predictability of efficacy extremely variable, based on other factors besides quantity and quality of the MSCs alone.
The chart below shows a comparison of stem cells derived from different tissue samples.[ii]
This relative comparison along with the quality of the health of the patient (host environment) brings rise to the importance of harvesting stem cells correctly (of course), processing the cells properly (of course), and then seeding the body with well-derived stem cell processing for the desired result (i.e., joint degeneration, soft tissue damage, stroke, etc..). This is all being done quite well, and improving rapidly each year as more technologies are developed to increase consistency and quality of processing.
Nevertheless, perhaps too much emphasis is currently placed on stem cell quantity and quality and far too little attention focuses on the host’s (patient’s) metabolic health, and the microvascular environment in which these stem cells are being introduced. The law of diminishing returns is seen throughout nature and is likely true in the case of stem cells from newborns, to teens, to the aged. When is too much more than enough when it comes to stem cells?
Our approach, whether gathering stem cells from adipose tissue, or from bone marrow aspirate, is to focus on a realistic and reasonably healthy density and quality of cells, using a high standard of care to harvest and process the cells into active stem cells (MSCs), and to introduce the stem cells into a host (patient) that has been properly prepped beforehand. In doing so, we can provide a lower cost of stem cell therapy to the patient, while maintaining a very high standard of care, in addition to concentrating on the role of metabolic health within the host environment, of which most stem cell practitioners are completely overlooking.
Stem Cell Fitness – The Search for the Most & Best
The chart below shows stem cell density taken from marrow over various age groups. As one can see, by the time we reach our teens, we’ve lost 80%-90% of our stem cells (MSCs) due to aging. This has led researchers to concentrate on the “more is better” myth. That is, we need stem cells from embryos or from discarded cord and placenta tissue donated from newborn births. Arguably, this will impact MSCs regenerative capacity, but one could argue even teens on average have significantly high levels of regenerative capacity, so we shouldn’t arbitrarily rule out harvesting and concentration of autologous stem cells from older adults.
