The first French clinical trial using human embryonic stem cells for regenerative purposes was launched in 2014, using the I6 stem cell line that was imported from Israel. From Israel to France, national reproductive policies and practices inform how basic scientists produce, manage and circulate cells across countries. Building on an interdisciplinary co-production involving two social scientists and a life scientist, this article suggests that biobanks passage cells from in vitro fertilization to stem cell science and from country to country by modifying their reproductive meaning. Four passages are described: the absence of cells in 2005 when the research started in France; the presence of supernumerary embryos available for research in Israeli IVF biobanks; the production of the I6 stem cell bank in Israel; the importation and laboratory biobanking of the cells in France. Human embryonic stem cell lines can never be completely disentangled from reproduction.

“I6 代：关于从以色列到法国的人类胚胎干细胞系的繁殖”

法国首个利用人类胚胎干细胞进行再生的临床试验于 2014 年启动，使用的是从以色列进口的 I6 干细胞系。从以色列到法国，国家生殖政策和实践告诉基础科学家如何在各国生产、管理和流通细胞。本文以两名社会科学家和一名生命科学家的跨学科合作为基础，建议生物库通过改变细胞的生殖意义，将细胞从体外受精转移到干细胞科学，并从一个国家传到另一个国家。描述了四段：2005 年在法国开始研究时没有细胞；以色列 IVF 生物库中存在可供研究的多余胚胎；以色列I6干细胞库的生产；法国细胞的进口和实验室生物库。人类胚胎干细胞系永远无法完全脱离繁殖。
