Stem cell 'major discovery' claimed Jan.31,2014
Stem cell researchers are heralding a "major scientific discovery", with the potential to start a new age of personalised medicine.
日本科學家發現便宜、安全的幹細胞;以後個人人體器官農場能實現了.
以下摘至"BBC News"
Scientists in Japan showed stem cells can now be made quickly just by dipping blood cells into acid.
Stem cells can transform into any tissue and are already being trialled for healing the eye, heart and brain.
The latest development, published in the journal Nature, could make the technology cheaper, faster and safer.
The human body is built of cells with a specific role - nerve cells, liver cells, muscle cells - and that role is fixed.
However, stem cells can become any other type of cell, and they have become a major field of research in medicine for their potential to regenerate the body.
Embryos are one, ethically charged, source of stem cells. Nobel prize winning research also showed that skin cells could be "genetically reprogrammed" to become stem cells (termed induced pluripotent stem cells).
Acid bath
Now a study shows that shocking blood cells with acid could also trigger the transformation into stem cells - this time termed STAP (stimulus-triggered acquisition of pluripotency) cells.
Dr Haruko Obokata, from the Riken Centre for Developmental Biology in Japan, said she was "really surprised" that cells could respond to their environment in this way.
She added: "It's exciting to think about the new possibilities these findings offer us, not only in regenerative medicine, but cancer as well."
The breakthrough was achieved in mouse blood cells, but research is now taking place to achieve the same results with human blood.
Chris Mason, professor of regenerative medicine at University College London, said if it also works in humans then "the age of personalised medicine would have finally arrived."
He told the BBC: "I thought - 'my God that's a game changer!' It's a very exciting, but surprise, finding.
"It looks a bit too good to be true, but the number of experts who have reviewed and checked this, I'm sure that it is.
"If this works in people as well as it does in mice, it looks faster, cheaper and possibly safer than other cell reprogramming technologies - personalised reprogrammed cell therapies may now be viable."
'Revolutionary'
The finding has been described as "remarkable" by the Medical Research Council's Prof Robin Lovell-Badge and as "a major scientific discovery" by Dr Dusko Ilic, a reader in stem cell science at Kings College London.
Dr Ilic added: "The approach is indeed revolutionary.
"It will make a fundamental change in how scientists perceive the interplay of environment and genome."
But he added: "It does not bring stem cell-based therapy closer. We will need to use the same precautions for the cells generated in this way as for the cells isolated from embryos or reprogrammed with a standard method."
And Prof Lovell-Badge said: "It is going to be a while before the nature of these cells are understood, and whether they might prove to be useful for developing therapies, but the really intriguing thing to discover will be the mechanism underlying how a low pH shock triggers reprogramming - and why it does not happen when we eat lemon or vinegar or drink cola?"

廈門自行車隊-廈門騎迹 Dec.12, 2013
騎單車的時間,加總起來也有5-6年了,還沒調來廈門之前,於2008年,在高雄成立了一個自行車隊,”華航高雄貨運鐵馬隊”.經過了4年多的運作,後因工作關係,奉派大陸,該車隊仍然繼續運行; 但改名稱為”華航之友鐵馬隊(chinaairbike.blogspot.tw).
2013年元月調駐廈門後,我個人仍不改騎車之樂趣,並也在公司內,成立了一支自行車車隊,名為”廈門騎迹”,blog.sina.com.cn/123xmn,於2013年12月開始約騎.每月兩次的騎行活動,帶動運風潮,走向健康;同事,貨代(客戶),機場公務單位均表歡迎,每月的約騎活動, 受到大家的關注,玩得不亦樂乎.
四川 九寨溝之旅Oct.19, 2013
九寨溝是我嚮往的大陸景點之一,老婆說:"參加11/19日的華航員工團",但又聽別人說:成都到九寨溝拉車太遠又危險,所以臨時決定參加當下最熱門的時段,10月下旬,四飛行程(所有航段均使用飛機),是九寨溝一年內最美的季節,也是最貴的費用.
很幸運地,我們第一天到黃龍山時,竟然下著大雪,讓我們興奮極了,但也擔心明日最美的九寨溝是否會受到天氣的影響?但極其幸運的,隔天出了個大太陽,讓我們攬盡了全中國最美的山和水.不多贅說,請觀賞右邊相簿連結.
桂林 灕江四日遊 Sep.03,2013
第一次參加大陸的國內旅行團,滿懷期盼,卻斷羽而歸.
首先,灕江風景之美,不在話下.值得一遊,但對大陸的旅行團,卻不感恭維.
大陸的旅行團的經驗...
1/不按事前說明書行程,隨意擅改.
2/推銷額外付費路線,令人騎虎難下.
3/吃住均差,旅館不到兩顆星;至於吃,更差了.
4/推銷白銀飾品;利用景點假借佛教斂財...等等不足而一.
我要說明的是,我們參加的團,四天三夜,RMB2,420.(約台幣12,100)/一位.
在廈門算是不便宜的旅行團,旅行社像廈門建發旅遊,中國旅行社,廈航國旅
在廈門算是高檔次的.但結果令人失望.
華航鐵馬隊廈門四日遊 Sep.12,2013
於是我們選定了 : 9/12(四）〜 9/15(日）.
當日09/12,老于頭夫妻,Tony,佳音走小三通;水和夫妻,阿杜走直飛班機,一群人於下午時段集合完畢.
•第一天 ..下午
廈門大學參訪,由廈大電機系研究生林同學帶領;晚餐:山東老鄉餐廳.
•第二天
古浪嶼(渡輪),由漢連貨代Ms.小翁(鼓浪嶼人)做導遊;
中午:參訪南普陀寺,中餐,南普陀素食餐廳;
傍晚,單車遊五緣灣;
晚上:隴上人家,大陸蘭州西北正宗烤羊肉大
•第三天,全日單車
南靖土樓一日遊,備補給車,單車由南靖縣城△345m,騎到書洋(福建土樓服務中心)△500m,共41km.爬坡度3.7%;可惜快到書洋時,遇大雨,為避免雨淋,5位勇腳(阿杜,水和,Tim,邱迪,小王/領騎)全部上車.
中餐/晚餐/全程補給:由南靖縣仕紳招待,感謝其盛情款待.
•第四天 ; 上午
