Stem cells

Stem cells - are undifferentiated cells capable of self-renewal

• Can differentiate into specialised cell types - potency

• Serve as a reservoir for tissue growth, repair and regeneration

Differentiate totipotent, pluripotent and multipotent stem cells based on origins and specialisations.

totipotent - have the potential to become any

pluripotent - produced have the potential to become any cell except embryonic

multipotent - certain range of cells

Uni potent - unspecialised cell

Define and explain how tumours are differentiated from cancers.

Outline the screening method, symptoms, causes and preventative strategies that help with early detection of the 4 named cancers.
