总之研究发现TRAP-1基因敲除小鼠表现出较少的与年龄相关的病症包括肥胖，炎症组织变性和自发形成的肿瘤等。
在加州大学圣地亚哥医学院神经修复中心主任、神经科学教授Mark Tuszynski博士和同事们将源自于一名86岁的健康男性的皮肤细胞转化为iPSCs后，研究小组将iPSCs重编程为神经元，把这些神经元放入到包含一些生长因子的基质中，然后研究人员再将它们移植到了脊髓损伤达2周的大鼠体内。
3个月后，研究小组在大鼠脊髓中发现了成熟的神经元，神经纤维跨越长距离广泛的生长，通过了损伤组织甚至延伸到了大脑中。尽管移植神经元和大鼠神经元之间存在大量的，但动物肢体的功能尚未得到恢复。研究人员指出，几个iPSC移植物都具有一些抗原抗体，有可能阻断了有益效应。
Tuszynski博士说：“这些结果表明，内在神经元机制可以轻易地克服脊髓损伤建立的障碍，将许多的轴突延伸很长的距离，且这些能力甚至在由非常老化的人类细胞重编程的神经元中持续存在。”
Tuszynski和Paul Lu以及合作者们，现正致力于鉴别利用来自患者自身细胞的移植物，转化神经干细胞疗法用于脊髓损伤患者的途径。
在人类的健康肠道中，干细胞会不断地彼此竞争得以生存，而在某一个时间某一个肠道区域往往只会存在一种特定数量的干细胞生存下来;然而当研究者调查早期肿瘤组织中的干细胞时，他们却发现随着干细胞生存竞争的剧烈增加，干细胞的数量也在相应增加，这就明显揭示了肠癌发生和干细胞活性之间的关系。
文章中，研究者利用一种特殊开发的“工具盒”对人类机体的干细胞进行研究，这种新型工具盒可以随机测定老化干细胞的突变情况，这种突变情况正表明了干细胞所发生的行为;在本项研究开展之前，关于人类肠道干细胞生物学的分子机制依然是个谜，而在这篇研究报道中研究者就解开了这一谜题;研究者利用小鼠进行试验，由于小鼠的肠道特性和人类的肠道特性具有明显的相似性，因此利用小鼠进行研究得到的结果就可以转化到人类机体中。

In conclusion, the study found that TRAP-1 knockout mice showed less age-related disorders including obesity, inflammatory tissue degeneration and spontaneous formation of tumors.
After Mark Tuszynski, professor of neuroscience at the University of California San Diego School of Medicine's neurorestoratology center and colleagues converted skin cells from an 86-year-old healthy male into iPSCs, the team reprogrammed iPSCs into neurons, The neurons were placed in a matrix containing some of the growth factors, and the researchers then transplanted them into rats that had been injured for up to two weeks.
Three months later, the team found mature neurons in the rat spinal cord, which grew extensively over long distances, damaged tissues and even extended into the brain. Despite the large number of connections between transplanted and rat neurons, the function of animal limbs has not been restored. Researchers pointed out that several iPSC implants have some antigenic antibodies, potentially blocking the beneficial effects.
Tuszynski said: "These results show that intrinsic neuronal mechanisms can easily overcome the barriers established by spinal cord injury, extending many axons over long distances, and these abilities even in neurons reprogrammed by very aged human cells In the persistence. "
Tuszynski and Paul Lu and collaborators are now working on identifying the best ways to use neural stem cell-based therapies for patients with SCI using grafts from their own cells.
In human healthy gut, stem cells constantly compete with each other to survive, and at some point there is often only one specific number of stem cells in one gut area; however, when investigators investigate stem cells in early tumor tissues They found that as the number of stem cells increased with the dramatic increase in competition for stem cell survival, this clearly revealed the relationship between colorectal carcinogenesis and stem cell activity.
In this article, the researchers used a specially developed "toolbox" to study human stem cells. This new toolbox allows for the random determination of mutations in aging stem cells, a mutation that is indicative of the behavior of stem cells. Before the study was carried out, the molecular mechanism of human gut stem cell biology remained a mystery, and in the report, researchers solved the mystery; researchers used mice to test that mice Of the intestinal traits and human intestinal characteristics have obvious similarities, so the results of the study using mice can be transformed into the human body.
