Cells generated by reprogramming adult cells to an embryonic-like state, enabling them to differentiate into a wide range of cell types.

Pluripotent Cells

Pluripotent cells are stem cells that have the capacity to differentiate into nearly all types of cells in the body, key for developmental processes and medical research.

Reprogramming

The process of converting one cell type into another, typically into a more primitive or undifferentiated state, often used in regenerative medicine and biology research.
