All stem cells have three general properties: ⠀
i) They are capable of dividing and renewing themselves for long periods ⠀
ii) They are unspecialized (e.g. they can’t transport oxygen molecules like red blood cells) & ⠀
iii) They can give rise to specialized cell types (through the process called differentiation). ⠀
Stem cells remain undifferentiated until certain physiological cues (physical or chemical cues) signal their differentiation.
