Adipose-derived Mesenchymal Stem Cell Secretome (AMSC Secretome)

The Adipose-derived Mesenchymal Stem Cell (AMSC) secretome is a complex collection of bioactive molecules, including growth factors, cytokines, chemokines, and extracellular vesicles, secreted into the extracellular space. It functions primarily through paracrine signaling to regulate physiological processes such as angiogenesis, tissue repair, and immune response modulation [1]. In therapeutic contexts, the AMSC secretome is leveraged for its potent anti-inflammatory and regenerative properties, showing promise in treating chronic wounds, osteoarthritis, and myocardial infarction [2]. Rather than acting on a single receptor, the secretome targets multiple extracellular and cell-surface proteins simultaneously, such as VEGF receptors to promote vascularization and various cytokine receptors to suppress systemic inflammation [3]. This multi-target approach allows for a comprehensive modulation of the tissue microenvironment, facilitating healing and reducing fibrotic scarring [4]. While it offers a cell-free alternative to traditional stem cell therapy, significant challenges remain in standardizing the secretome's composition and ensuring long-term safety in diverse patient populations [5].
