And there is some evidence that iPS cells aren't exactly like embryonic stem cells in their gene expression, retaining a subtle cellular memory of the tissue they came from.
已有一些证据证实诱导多能干细胞在基因表达方面，并不与胚胎干细胞完全相同，它仍保留有其来源组织的一些细胞记忆。
A similar study from researchers at Children's Hospital Boston, published simultaneously in the journal Nature, also finds that cellular "memory" affects the differentiation potential of iPSCs.
同时，波士顿儿童医院的科研人员也做了相似的研究，研究结果已在《自然》杂志上发表。他们认为，细胞的记忆确实影响诱导多能干细胞的分化能力。
