A tumour risk linked to some pluripotent cells — avoided by characterised, regulated protocols.
A tumour formed when pluripotent or poorly differentiated stem cells develop uncontrollably into multiple cell types (hair, bone, fat mixed chaotically). It's the main theoretical risk of pluripotent stem-cell therapy. Teratomas are rare in clinical practice with differentiated cells (bone-marrow MSCs, cord blood), but the risk is non-zero if pluripotent cells aren't fully controlled. Ask clinics whether they use pluripotent cells and, if so, what safety monitoring they employ (imaging at 3, 6, 12 months post-injection) to detect early tumour development. Reputable clinics avoid pluripotent cells for clinical work or apply rigorous differentiation protocols.
StemCellAtlas is your guide to stem-cell therapy: what the evidence shows, which conditions are treated, and the real all-in cost by country — typically €3,000–8,000 with our partner Stem Plus (Sofia), Europe's lowest-cost EU destination, versus $15,000–35,000 in the US.
