Your Own Fat Contains Powerful Healing Cells
Fat tissue is far more than just energy storage. Scientists now know it contains a rich mix of regenerative cells that can support healing throughout your body. Among these are mesenchymal stem/stromal cells (MSCs)—special cells that can help repair damaged tissues. This review examines the different ways doctors can harness these healing cells from your own fat tissue to treat musculoskeletal problems.
Three Ways to Use Fat Tissue for Healing
Doctors can process fat tissue in three main ways for regenerative treatments. First, they can create micro-fragmented adipose tissue (like Lipogems®), which keeps tiny clusters of fat intact with all their natural healing cells and structure preserved. Second, they can produce stromal vascular fraction (SVF), a mixture of various cell types separated from the fat. Third, they can isolate and grow adipose-derived stem cells (ASCs) in a laboratory over several weeks.
Each approach has trade-offs. Micro-fragmented fat and SVF can be prepared during a single procedure, making treatment simpler and more affordable. Laboratory-expanded cells require two separate procedures and specialized facilities, but provide a more uniform cell population.
Micro-Fragmented Fat Preserves Nature's Healing Environment
One key advantage of micro-fragmented adipose tissue is that it maintains the natural "neighborhood" where healing cells live. The processing removes blood and oils—which can cause inflammation—while keeping the tissue's structure intact. These tiny fat clusters, measuring just fractions of a millimeter, contain all the original cell types working together as nature intended.
Research shows that both micro-fragmented fat and SVF have similar numbers of healing cells per gram. However, micro-fragmented fat appears to have less blood contamination, which may reduce unwanted inflammation after injection.
Safety Confirmed Across Multiple Clinical Studies
Both micro-fragmented fat and SVF have demonstrated anti-inflammatory and healing effects in animal studies. More importantly, a growing number of clinical trials have confirmed their safety in humans, including for musculoskeletal conditions like joint problems. This safety record, combined with practical advantages over laboratory-expanded cells, has made these treatments increasingly popular among orthopedic specialists.
Fat Tissue Offers More Stem Cells Than Bone Marrow
Interestingly, fat tissue contains up to three percent MSCs—far more than bone marrow, which holds only about 0.002 to 0.02 percent. This abundance makes fat an excellent source for regenerative treatments. Scientists believe these healing cells naturally live near blood vessels, where they help maintain healthy tissues and respond when injuries occur.
What This Means for Your Treatment Decision
This scientific review confirms that fat-based regenerative treatments offer a promising option for musculoskeletal conditions. Micro-fragmented adipose tissue technology like Lipogems® provides several potential benefits: it uses your own cells (reducing rejection risk), preserves the natural healing environment, can be completed in a single procedure, and has demonstrated safety across numerous studies.
While research continues to determine which specific conditions respond best to these treatments, the evidence supports fat-based therapies as a reasonable option to discuss with your doctor if you're seeking alternatives for joint pain or muscle problems.

Adipose-Derived Stem/Stromal Cells, Stromal Vascular Fraction, and Microfragmented Adipose Tissue
Enrico Ragni, Marco Viganò, Paola De Luca, Edoardo Pedrini, Laura de Girolamo · 2021
Adipose tissue has evolved from being considered merely energy storage to being recognized as a regulator of energy balance, bone metabolism, hematopoiesis, and inflammatory response. This highly vascularized structure contains a heterogeneous mixture of cell populations, including mesenchymal stem/stromal cells (MSCs). The presence of adipose-derived stem/stromal cells (ASCs) has drawn significant clinical attention due to their paracrine effects and multipotent differentiation capacity, with successful applications in musculoskeletal conditions, cardiac diseases, ischemia, neurological disorders, and metabolic diseases. Adipose tissue can be processed through two main approaches: isolation and culture expansion of ASCs, or point-of-care processing to obtain adipose-derived products. The latter includes stromal vascular fraction (SVF), obtained through enzymatic or mechanical tissue dissociation, and microfragmented adipose tissue (microfat), obtained through mechanical processing only. SVF comprises heterogeneous freshly isolated cells excluding mature adipocytes, while microfat preserves tissue microarchitecture and all cell types within their native niche. Culture-expanded ASCs provide standardized stem/stromal cell populations matching International Society for Cellular Therapy criteria, though SVF and microfat offer practical advantages as point-of-care therapies. Both approaches demonstrate anti-inflammatory, immunomodulatory, and reparative effects, with increasing clinical applications, particularly in orthopedic conditions.
