Lipogems®: an innovative technique for tissue regeneration

Adipose Tissue: a valuable source of stem cells.

Thanks to its high vascularity, the Adipose Tissue (AT) has outstanding natural regenerative properties. [1] Surrounding the network of capillaries, there are lots of pericytes: precursors of Mesenchymal Stem Cells (MSC). When the wall of a capillary suffers a trauma, pericytes are released into the interstitial space and become MSC. These stem cells are able to release growth factors and anti-inflammatory cytokines, accelerating and improving the process of wound healing. [2]

AT is the ideal source for obtaining stem cells; not only because of the high concentration of MSC, but also because it can be easily extracted with minimal invasive surgery: lipoaspiration. [3]

Which is the most effective way to obtain those MSC? Lipogems ®

The most used techniques for fat grafting have been compared in clinical trials, and Lipogems® showed to be the method with the best washing quality, the easiest to graft and the best one to preserve the structural integrity of the MSC. [4]

Lipogems®, result of Dr. Carlo Tremolada’s patents, is a disposable medical device, authorized by the FDA, which optimizes the lipoaspirate intended for autologous implantation. It consists in a closed circuit, in absence of air, which processes the lipoaspirate reducing 10 times the dimensions of the adipose tissue clusters (from 3mm to 0,3mm); therefore the superficial area is highly increased, over 6000 times. It generates Micro-Fragmented Adipose Tissue (MFAT), preserving the structural integrity and the biological activities of each cell. [5]

This device is based on the use of mild mechanical forces, which allows cleaning the lipoaspirate from impurities with pro-inflammatory effects such as oily residues, blood and dead cells. This technology improves and optimizes the natural properties of adipose tissue. It does not require enzymes, additives, or centrifugations. The MFAT is only immersed in physiological solution, which protects the cells from possible damage. The intact stem cells are minimally manipulated, and therefore they are able to preserve all their natural biological properties.

Benefits of MFAT injections [6,7]

  1. Reduce risk of sepsis due to their antibacterial role

  2. Decrease inflammation

  3. Increase the release of growth factors and reparative cytokines

  4. Induce angiogenesis: the formation of new blood vessel

  5. Reduce pain and recovery time

  6. Promote wound healing by increasing cell migration, differentiation and proliferation

Clinical applications of Lipogems®

As the main function of the MFAT injections is to improve the regenerative process, they have many current implementations in different fields, such as:

  • Orthopedics: osteoarthritis, cartilage defect repair, joint arthritis, osteochondritis, tendinopathies. [8]

  • Plastic Surgery and Aesthetic Medicine: lifting, blepharoplasty, breast augmentation, anti-age treatments, and treatments for scars and burns. [3,4]

  • Oral and Maxillofacial Surgery: temporomandibular joint arthrocentesis, mandibular reconstruction. [9]

  • Vascular Surgery: diabetic foot ulcerations, chronic ulcerations.[10]

  • Coloproctology: perianal fistulas, Crohn’s disease, fecal incontence. [11]

  • Gynecology: urogenital atrophy, vulvovaginal dystrophy, urinary incontence. [12]

Lipogems® future perspective

It is important to highlight that this is a reliable method which has shown biological activities in both in vitro and in vivo assays. Moreover, it is supported by over 100 peer reviewed publications.

Nowadays, several clinical trials are being carried out to track new possibilities to implement this innovative therapeutic strategy in new fields. Therefore, we can conclude that Lipogems®, with only 8 years of implementation, is the new advanced key in the field of tissue regeneration. Looking prospectively, we can see how promising Lipogems® is, and its potential growth in almost every field of health sciences.
