Therapeutic potential of the stromal vascular fraction in COVID-19

The new coronavirus infection (COVID-19) is already known to cause serious respiratory illnesses such as pneumonia and lung failure. COVID-19 has caused catastrophic damage to the public health, economic and social stability. As COVID-19 has resulted in enormous human toll and serious economic loss that poses a global threat, urgent understanding of the current situation and the development of strategies to mitigate the spread of the virus is required. Today, many studies are being carried out around the world to study the pathogenesis of COVID-19, where the development of a “cytokine storm” or pulmonary fibrosis is a serious complication that can lead to unfavorable outcomes. This leads to the fact that a deeper understanding of the nature of the virus will allow to develop new approaches in pathogenetic therapy. In this regard, the stromal vascular fraction has tremendous therapeutic potential in COVID-19. Stromal vascular fraction provides anti-inflammatory and immunomodulatory effects and promotes the restoration and regeneration of damaged tissues. The availability, the ability to obtain a significant volume of viable cells of the stromal vascular fraction population, such as adipose tissue stem / stromal cells, as well as their use by the intravenous route, has proven safe and effective in other forms of lung disease, including fibrotic diseases. In other words, the goal of this therapy for COVID-19 is to eliminate the inflammatory process, restore trophic and regenerate damaged tissues, and remodel fibrous and connective tissue. However, stromal vascular fraction is not currently approved for the prevention or treatment of COVID-19 cases. However, clinical trials are ongoing to ensure maximum understanding in terms of efficacy and safety. In this paper, we will discuss this new approach to the use of stromal vascular fraction therapy, which serves as a “ray of hope” in the fight against severe forms of COVID-19
