68. What is the difference between prospective and retrospective lineage analysis?

		Prospective lineage analysis establishes cell trajectories while retrospective defines cell ancestry
		The difference is in the method used to label cells at time A (time zero)
		Prospective lineage analysis involves labeling at time A and analysis at time B while retrospective reconstructs lineages backwards in time
		Both methods construct ancestry from time A to B but prospective uses labeling and retrospective uses mutations
