Regenerative cells can be embryonic or adult cells found in tissues. Adult regenerative cells are obtained from tissues like fat and act as the repair system for the body. Regenerative cells can self-renew and differentiate into specialized cells. Research on regenerative cells shows promise but progress is slower than reported. Mesenchymal regenerative cells found in fat and bone marrow can differentiate into multiple cell types and have anti-inflammatory properties, making them a potential therapy for immune-mediated diseases. Adipose-derived regenerative cell treatment involves harvesting stromal vascular fraction cells from fat which contain regenerative cells and growth factors and injecting them back into patients to potentially replace damaged cells and reduce inflammation.
