Unlike the genome project, which had a clear end point, known in advance (the number of genetic " letters" in the human genome could be calculated by measuring how much DNA it contained), the Cell Atlas project's goal is fuzzy.

不同于基因组计划， 它有一个明确的终点，事先知道（人类基因组中遗传“字母” 的数量可以通过测量它包含多少 DNA 来计算），Cell Atlas 项目的目标是模糊的。
