The next step, says Dr Ruohola-Baker, is to try to boost enamel production even further, with a view to eventually beginning clinical trials.

罗霍拉-贝克博士说，下一阶段是进一步促进牙釉质的产生，并最终开始临床试验。

But in a paper published in Cell, Hannele Ruohola-Baker, a stem-cell biologist at the University of Washington, and her colleagues offer a possible alternative.

但是在《细胞》杂志上发表的一篇论文中，华盛顿大学的干细胞生物学家汉内莱·罗霍拉-贝克和她的同事提供了一种可能的替代方法。

Armed with that information, Dr Ruohola-Baker and her colleagues next checked to see whether the stem cells could be persuaded to transform into ameloblasts.

以这些信息为依据，Ruohola-Baker博士和她的同事接下来检查了干细胞是否可以转化为颈关节。
