Stem cell treatment for diabetic foot – how does it work?
Because of their regenerative properties, stem cells are becoming a useful tool in the treatment of foot ulcers in diabetes, also known as “diabetic foot”. This is an innovative method of cell therapy available as an experimental treatment in a few specialized medical centres around the world.
Stem cells are a unique component of the body, capable of “transforming” into almost any tissue of the body and replacing its damaged parts. Because of this, they promote faster healing of wounds and ulcers in diabetic patients, improve the survival prognosis of patients, and in many cases avoid the need for amputation.
Diabetic foot is one of the most common complications of diabetes mellitus. It is characterized by the formation of a necrotic ulcer on the lower leg, accompanied by neuropathy (nerve damage) and/or peripheral artery disease. The most common cause is arterial thrombosis. The disease does not heal well and can lead to amputation.
Because of their versatility, stem cells contribute to the rapid treatment of diabetic foot on several levels at once:
Formation of new cells involved in wound healing: myofibroblasts, keratinocytes, pericytes and endothelial cells;
Release of paracrine factors – substances that affect skin tissues and “trigger” skin healing mechanisms;
Remodelling of the extracellular matrix – the process by which wound healing occurs;
Formation of new capillaries;
Regeneration of nerve endings;
Improvement of collagen deposition;
Immunomodulation;
Suppression of inflammatory processes.
In most cases, autologous stem cells derived from the patient’s own body are used for cell therapy. They can usually be easily harvested and the treatment process is safe. However, patients with diabetes often have a reduced number of stem cells in the body. Therefore, it may be necessary to take medications that stimulate stem cell production in the bone marrow (G-CSF) or to seek a donor before starting treatment.
For each patient who comes to the clinic with diabetic foot, an individual treatment protocol is selected, depending on the characteristics of the course of the disease. Often the best prognosis is observed when stem cell therapy is combined with classical treatment protocols for diabetic foot ulcers:
Balloon angioplasty is a surgical procedure that involves dilating a vessel by inserting an inflatable “balloon” into it to improve blood flow to the affected area of the leg.
Stenting is the placement of a small, expandable, mesh-like tube that supports the vessel and helps keep it open.
Removal of dead tissue from the ulcer is usually performed with a scalpel.
Infection control. Diabetic patients are 2-4 times more prone to developing infections at the wound site, therefore increased attention is given to preventing them. Antibiotics and various hygienic procedures are implemented.
Proper weight distribution on the foot plays a big role in wound healing. Diabetic patients’ shoes should always be comfortable and orthopaedic. Sometimes doctors may put staples or a cast on the foot.
The European Wound Management Association (EWMA) states that “the emphasis in wound care for the diabetic foot should be on radical and repeated removal of dead tissue, frequent inspection and bacterial control, and a careful balance of moisture.”
Also, some novel methods are used in foreign clinics:
Vacuum wound care
A wound dressing is applied using a special vacuum machine, which automatically removes excess fluid and thereby reduces the risk of infection.
Hyperbaric Oxygen Therapy
This treatment has an antibacterial effect and also improves local tissue perfusion, stimulates the production of growth factors, collagen synthesis and the formation of new capillaries.

Why does diabetic foot develop?
Several factors usually play a role in the development of diabetic foot ulcers, related to the general metabolic dysfunction of the body. Elevated glucose levels often lead to the development of atherosclerosis, which causes the tissues of body parts distant from the heart – most notably the feet and fingertips – to have insufficient blood flow. Diabetes also impairs the immune system, which increases the risk of infections in this group of patients.
Hyperglycemia and insulin resistance often leads to bone marrow mobilopathy, a complication in which stem cells are not transported from the bone marrow into the bloodstream. This prevents them from “repairing” blood vessels and capillaries as they do in a healthy body, which increases the risk of vascular disease.
Risk factors for the development of diabetic foot include:
Neuropathy;
Narrowing or thrombosis of arteries in the legs;
Physical injuries;
Uncomfortable/uncomfortable shoes.
According to the American Diabetes Association (ADA), 25% of patients with this diagnosis will have problems with normal wound healing during their lifetime.
The difficulty in treating the diabetic foot is that the natural tissue regeneration processes in patients with diabetes mellitus are damaged. Insufficient blood flow to the foot, neuropathy, and metabolic disorders cause the standard protocols used in medicine to be insufficiently effective.
What are the warning signs of the diabetic foot that patients should look out for?
Changes in skin and nail colour;
Cuts, blisters, blisters and sores on the feet, especially those that secrete fluid or pus;
Loss of sensitivity to temperatures;
Pain, numbness, tingling;
Unpleasant odour;
Swelling of the lower extremities.
Comparison of different types of diabetic foot treatment using stem cells
The methods of applying stem cells can be different – injections, sprays, gels, etc. Since the method is still under research, there is no single treatment protocol. The approaches of different clinics may differ from one another, so you need to be careful when choosing a medical institution where the treatment will take place.
Most clinics use injections of autologous stem cells into a leg ulcer in the treatment of diabetes.
Type of procedure | Advantages | Disadvantages |
---|---|---|
Source of stem cells | ||
Mesenchymal stem cells taken from bone marrow | The need for bone marrow puncture Low concentration of stem cells The efficiency of treatment is affected by comorbidities | |
Mesenchymal stem cells isolated from blood | Safe procedure Simple cell harvesting protocol | Treatment effectiveness is affected by comorbidities G-CSF drugs are necessary |
Mesenchymal stem cells derived from adipose tissue | Relatively safe procedure | Efficiency is affected by comorbidities |
Stem cells derived from cord blood (rarely used) | The patient does not need to undergo additional procedures to harvest stem cells | Low concentration of stem cells Possible immune incompatibility Pre-frozen cord blood or access to the bank is necessary |
Donor type | ||
Autologous (the source of stem cells is the patient themselves) | Full immunocompatibility, no risk of related complications | Lower concentration of stem cells Limited treatment potential |
Allogeneic (stem cell source is a donor) | Source of healthy stem cells | Time required to find a donor |
Type of injection | ||
Local injection | Easy to use Low risk of complications Relatively inexpensive | A high percentage of stem cells fail to engraft and die Unable to control the location of stem cells The wound may require surgery |
Sprays and drops | Painless Easy to use Low risk of complications Relatively inexpensive | A high percentage of stem cells fail to engraft and die Impossible to control the location of stem cells The wound may require surgery |
Hydrogels and scaffolds | Low risk of complications Controlling the location of stem cells Stem cells engraft better | Complex protocol More expensive procedure The wound may require surgery |
Endovascular injection | Conducted during angioplasty Positive effect on immunomodulation and glucose optimization | More expensive procedure Stem cells do not engraft well Risks associated with vascular surgery |
What results can be expected from the treatment?
Stem cell therapy improves tissue regeneration abilities and promotes faster and easier wound healing in diabetes.
The effectiveness of this method depends on the body’s response and averages 40-60%.
Studies also show that stem cell therapy combined with angioplasty (stenting or ballooning) has better results than either method on its own. Many patients can avoid leg amputation.
