		Under some conditions, cells can “roll back” differentiation all the way to pluripotency (de-differentiation)
		Under some conditions, cells can switch directly to an alternate fate (trans-differentiation)
		Once cells fully differentiate, they can never change their fate
		Cell fate decisions are made when cells respond to cues and choose between alternate “valleys”
