在小鼠中进行的这项研究也显示肾脏自我更新的能力。不是单一型的肾干细胞就可替换任何丢失或受损的肾脏组织，而是驻留在肾脏的不同部分稍微??更专门的干细胞产生每个类型的肾组织??内的新细胞。
“这就像有分支的树，其中每个分支考虑其自身的成长，而不是依赖于躯干的照顾，”德克尔说。
科学家还发现，这些细胞是通过一个名为Wnt蛋白的细胞通路的活化作出生长的决定。Rinkevich说，即使肾上皮细胞的数量看起来一样，zui健壮肾脏形成能力可追溯到前体细胞中的Wnt信号被激活，并且只能生长为某些特定类型的肾组织。“这提示了Wnt信号是负责新肾组织的成长提供了一个治疗目标，以通过促进或恢复肾脏的再生能力，”他说。“我们也许能够打开Wnt信号通路产生新的肾脏形成细胞。”
研究人员说，这项研究发现对于科学家试图在实验室创造肾部分有着至关重要的影响。
然而，他们警告说，这样的进步并不迫在眉睫。“为了在实验室里长出整个肾脏是复杂的，因为我们需要协调许多不同种类的前体细胞的活性，” 德克尔说。“这不象血液和免疫系统可以从一种类型的干细胞再生。”
奥地利科学技术研究所(IST)的副教授Harald Janovjak，与维也纳医学大学癌症研究学会的副教授迈克尔·格吕施，一起利用光“遥控”癌细胞的行为，相关文章发表于本周的EMBO杂志上。这项工作*将光遗传学应用到癌症研究的新领域。
为了解细胞信号的动态，研究人员需要将膜受体蛋白激活和使其失活，膜受体蛋白作为一个细胞内外世界之间的中转站。理想情况下，这种激活在短时间(几秒到几分钟)以及近的目标位置(微米到毫米)内发生。然而，如此高水平的活化精密度不能使用当前的药理学和遗传学的方法来实现。光遗传学利用光来控制细胞的活性，以及具有在时间和空间上精确地被应用和移动(施加和除去)的优点。Janovjak，格吕施和同事重新设计受体酪氨酸激酶(RTKs)，在光的控制下，感测生长因子和激素的必要的细胞表面受体。

This study, conducted in mice, also shows the kidney's ability to self-renew. Rather than a single type of kidney stem cell that replaces any lost or damaged kidney tissue, it resides in a slightly more specialized, more specialized stem cell that produces new cells within each type of kidney tissue.
"It's like a tree with branches, each of which takes into account its own growth, not its torso care," Decker said.
Scientists also found that these cells are the decision to grow through the activation of a cellular pathway called Wnt protein. Rinkevich said that even though the number of renal epithelial cells looks the same, the most robust kidney formation can be traced back to the activation of Wnt signaling in precursor cells and can only grow to certain types of kidney tissue. "This suggests that Wnt signaling is responsible for the growth of new kidney tissue and provides a therapeutic target to promote or restore the regenerative capacity of the kidneys," he said. "We may be able to turn on the Wnt signaling pathway to produce new kidney-forming cells."
The researchers said the study found a crucial impact on scientists trying to create parts of the kidney in the lab.
However, they warned that such progress is not imminent. "To grow an entire kidney in a lab is complicated because we need to coordinate the activity of many different kinds of precursor cells," Decker said. "It's not like the blood and the immune system can regenerate from one type of stem cell."
Harald Janovjak, an associate professor at the Austrian Institute of Science and Technology (IST), and Michael Gruissch, an associate professor at the Institute for Cancer Research at the University of Wien University, are using light to "control" cancer cells in an article published in this week's EMBO magazine. This work, for the first time, applies optogenetics to new areas of cancer research.
To understand the dynamics of cell signaling, researchers need to activate and inactivate membrane receptor proteins, which act as a transit site between the cell's inner and outer cells. Ideally, this activation occurs within short periods of time (seconds to minutes) and near target locations (micrometers to millimeters). However, such a high level of activation precision can not be achieved using current pharmacological and genetic approaches. Photogenetics uses light to control the activity of cells, and has the advantage of being precisely applied and moved (applied and removed) in time and space. Janovjak, Gruch and colleagues redesigned their receptor tyrosine kinases (RTKs) to sense the necessary cell surface receptors for growth factors and hormones under the control of light.
