Stem cells are transplanted to replace damaged tissue. Some transplanted cells continue dividing without control.
Which outcome is a risk of this treatment?
The cells may become specialised and repair tissue.
The cells may stop dividing and remain undifferentiated.
The cells may form a tumour in the tissue.
The cells may differentiate and replace damaged cells.
