stromal cell-derived factor 1 (SDF-1)

Stromal cell-derived factor 1 (SDF-1), also known as CXCL12, is a natural protein in the body that acts as a signaling molecule. It guides the movement of certain cells, especially immune cells and stem cells, to areas where they are needed, such as sites of injury or tissue repair. SDF-1 plays a key role in processes like immune response, healing, and the formation of blood vessels. It interacts with specific receptors on cell surfaces, helping cells locate and respond to various physiological signals essential for maintaining health and healing wounds.
