Abstract (original English)

Concentrated growth factor (CGF) is an autologous blood-derived product widely used in regenerative medicine due to its high concentration of growth factors and platelets. In this study, the ability of primary stem cells isolated from human CGF to differentiate into adipocytes, endothelial cells, and neuronal-like cells was evaluated in vitro. CGF primary cells (CPCs) were obtained from CGF fragments and characterized after one month in culture. These cells were positive for the surface markers CD105, CD45, CD31, and CD14, and also expressed mRNA levels of the stemness markers Nanog and Oct3/4 comparable to human bone marrow mesenchymal stem cells (BMSCs). Results showed that, following appropriate differentiation protocols, CPCs, similarly to BMSCs, were able to differentiate into adipogenic, endothelial, and neuronal lineages, acquiring specific phenotypic and molecular markers. Adipogenic induction resulted in lipid accumulation and the upregulation of key genes, including PLIN2, FABP4, CD36, and FASN. Under pro-endothelial conditions, the cells exhibited increased expression of endothelial markers, eNOS, VEGFR-2, and CD31. Neuronal induction promoted the expression of β-tubulin III, Nestin, and Neurofilament. Overall, this work highlights the remarkable plasticity of CPCs and supports their potential application in multilineage regenerative therapies.
