這項研究由心臟科副教授Reza Ardehali博士和同事進行，解決了zui近關(guān)于心臟肌肉是否具有自我再生的力量的爭論。該研究結(jié)果也對于未來研究心臟組織的再生修復(fù)損傷導(dǎo)致疾病或心臟病非常重要。這項研究結(jié)果發(fā)表于2014年5月29日的《PNAS》雜志上。
zui初人們認為心臟肌肉細胞，或心肌無法自我復(fù)制，它們的總數(shù)與出生的時候一樣。然而，在過去的二十年研究中已表明，這些心肌細胞具有有限的增殖活性，盡管科學(xué)界沒有明確給出原因以及數(shù)量。
在某種程度上，很難找到用來衡量這種潛在的細胞分裂的間接方法，有時這種方法并不準確，難以達成科學(xué)共識。有些研究組使用碳年代測定法檢測人類心肌細胞的年齡，以確定它們是否為初始胎兒發(fā)育后分裂，但這種技術(shù)的準確性有爭議。其他發(fā)表的理論表明，心臟肌肉具有一個非常高的增殖能力; zui近，許多這些論文被撤回，因為同行們無法復(fù)制這些數(shù)據(jù)。
創(chuàng)建一個直接測量的模型
為了解決測量問題，Ardehali和他的同事開創(chuàng)了稱為馬賽克分析雙標記(或MADAM)的新穎遺傳方法，*次直接測量小鼠模型的心臟細胞分裂。他們發(fā)現(xiàn)心肌細胞分裂是有限的，終身對稱的，雖然小鼠中這種明顯的現(xiàn)象很少見，但在*個月的生活后顯著減小。研究人員說，并沒有任何的干細胞參與這一過程，以及心肌細胞的分裂每年僅限于不到1%。
研究人員說，子代的心肌細胞是這種罕見的細胞分裂的產(chǎn)品也能夠分裂，這很不平常(以前沒有研究發(fā)現(xiàn)過這種現(xiàn)象)?？茖W(xué)家發(fā)現(xiàn)，細胞分裂的速度并沒有隨著小鼠心肌梗塞誘導(dǎo)的一個修復(fù)反應(yīng)而提高。
“這是顯示心臟再生力量非常有限的zui有說服力的和直接的方式之一，” Ardehali說。 “這是一個非常令人興奮的發(fā)現(xiàn)，因為我們希望利用這些知識zui終能夠使心臟組織再生。其目的是確定參與心肌細胞對稱分裂的分子途徑，以及在疾病或受傷后使用它們來誘導(dǎo)再生補充心臟肌肉組織。”
人類的免疫系統(tǒng)是非常復(fù)雜的，它有著大量不同的細胞具有各種各樣的功能，這確保侵入的微生物如病毒或細菌能夠迅速地使之無害并保持整個機體的健康。
免疫系統(tǒng)還包括自然殺傷細胞(NK細胞)，其識別并消除腫瘤或病毒感染的細胞。因此，NK細胞對抗人體自身的應(yīng)激細胞以防止它們成為一個潛在的危險。然而，這種承擔是有風(fēng)險性的。其他的免疫細胞——特異性殺傷細胞，也被稱為CD8 + T細胞，響應(yīng)于病毒感染時不斷地繁殖和變得成熟，也可以表現(xiàn)出應(yīng)激癥狀，從而可能終結(jié)在NK細胞的名單上。

The study, conducted by Dr. Reza Ardehali, an associate professor of cardiology, and colleagues resolved the recent controversy over whether the heart muscle has the power to regenerate itself. The results of this study are also of great importance for future studies on regenerative repair of cardiac tissue leading to disease or heart disease. The study was published in the May 29, 2014 issue of PNAS.
Initially, people thought that heart muscle cells, or myocardium, could not replicate themselves, and their total number was the same as when they were born. However, in the past two decades of studies, it has been shown that these cardiomyocytes have limited proliferative activity despite the fact that the scientific community has not clearly given the reason and the quantity.
To some extent, it is difficult to find an indirect way to measure this potential cell division, which is sometimes not accurate enough to reach a scientific consensus. Some groups use carbon dating to test the age of human cardiomyocytes to determine whether they are post-embryonic developmental fissures, but the accuracy of this technique is controversial. Other published theories show that cardiac muscle has a very high proliferative capacity; recently, many of these papers have been withdrawn because of their inability to replicate these data.
Create a model for direct measurement
In order to solve the measurement problem, Ardehali and his colleagues pioneered a novel genetic approach called mosaic analysis double labeling (or MADAM), the first direct measurement of cardiac cell division in mouse models. They found that cardiomyocyte division was limited and life-long symmetrical, although this notable phenomenon in mice was rare but significantly reduced after the first month of life. The researchers said that no stem cells involved in this process, and myocardial cell division is limited to less than 1% per year.
It is not uncommon for researchers to say that offspring of cardiomyocytes are the rare products of cell division that divide (this has not been done before). Scientists found that the rate of cell division did not increase with a repair response induced by myocardial infarction in mice.
"This is one of the most persuasive and direct ways to show that the power of heart regeneration is very limited," Ardehali said. "This is a very exciting finding because we hope to eventually use this knowledge to regenerate heart tissue and its purpose is to identify the molecular pathways involved in the symmetrical division of cardiomyocytes and their use in the event of illness or injury to induce regenerative heart replenishment Muscle tissue. "
The human immune system is very complex. It has a large number of different cells that have a variety of functions that ensure that invading microbes, such as viruses or bacteria, can quickly be rendered harmless and maintain the health of the entire body.
The immune system also includes natural killer cells (NK cells) that recognize and eliminate tumor or virus-infected cells. Therefore, NK cells fight the body's own stress cells to prevent them from becoming a potential danger. However, this commitment is risky. Other immune cell-specific killer cells, also known as CD8 + T cells, may also display stress symptoms in response to continued multiplication and maturation of the virus infection and may thus end up on the NK cell list .
