Cells Derived from Concentrated Growth Factor Exhibit a Multilineage Differentiation Capacity

Area of Science:

• Regenerative Medicine
• Stem Cell Biology
• Biomaterials

Background:

• Concentrated growth factor (CGF) is an autologous blood product rich in growth factors and platelets.
• CGF is utilized in regenerative medicine for its therapeutic properties.

Purpose of the Study:

• To investigate the differentiation potential of primary stem cells isolated from human CGF (CPCs).
• To evaluate CPCs' ability to differentiate into adipocytes, endothelial cells, and neuronal-like cells in vitro.
• To compare CPCs' stemness and differentiation capacity with human bone marrow mesenchymal stem cells (BMSCs).

Main Methods:

• CPCs were isolated from CGF fragments and cultured for one month.
• Cell surface markers (CD105, CD45, CD31, CD14) and stemness markers (Nanog, Oct3/4) were analyzed.
• Standard differentiation protocols were applied for adipogenesis, endothelial differentiation, and neuronal induction.

Main Results:

• CPCs expressed key stemness markers comparable to BMSCs.
• CPCs successfully differentiated into adipocytes, showing lipid accumulation and upregulation of PLIN2, FABP4, CD36, FASN.
• CPCs differentiated into endothelial cells, increasing expression of eNOS, VEGFR-2, CD31.
• CPCs underwent neuronal differentiation, expressing β-tubulin III, Nestin, and Neurofilament.

Conclusions:

• CPCs possess significant multipotent differentiation capabilities.
• The findings support the potential of CPCs for diverse regenerative therapies.
• CPCs demonstrate remarkable plasticity, similar to BMSCs.
