整整一天,胰腺都在調(diào)節(jié)人體的血糖水平,通過分泌胰島素對餐后葡萄糖增加作出反應(yīng),這有助于細(xì)胞吸收糖類。在1型糖尿病的患者中,其自身免疫系統(tǒng)會錯誤地殺死β細(xì)胞,而原因尚未明了,且身體不能沒有胰島素。人們通過注射仔細(xì)校準(zhǔn)劑量的胰島素來控制他們的糖尿病。但是,這與從健康胰腺獲得的精確胰島素控制幾乎無法匹配,所以研究人員幾十年來希望找到一種方法來代替失去的細(xì)胞。
當(dāng)科學(xué)家在1998年分離出人類胚胎干細(xì)胞(ES細(xì)胞)時,希望一路飆升。ES細(xì)胞是多能的,這意味著在理論上它們可以轉(zhuǎn)變成身體的任一種細(xì)胞,包括β細(xì)胞。事實(shí)上,研究人員首要研究之一是,試圖使用ES細(xì)胞制造出胰島β細(xì)胞。后來,他們試圖使用所謂的誘導(dǎo)多能干細(xì)胞(iPS細(xì)胞),通過將體細(xì)胞重編程成胚胎樣狀態(tài)進(jìn)行。無論哪種方式,“這被證明是一個非常復(fù)雜的工作,” 納什維爾的范德比爾特大學(xué)研究胰腺發(fā)育的馬克·麥格納遜說。
幾個研究團(tuán)隊(duì)已經(jīng)把干細(xì)胞分化成β細(xì)胞的前體,當(dāng)放入實(shí)驗(yàn)動物時才成熟。但這些細(xì)胞需要6周才能*成為功能性β細(xì)胞,并且它們不易在體外研究。然而,臨床試驗(yàn)已在上個月開始測試它們用于患者的療效。
The whole day, the pancreas are regulating the body's blood sugar levels, through the secretion of insulin to respond to increased postprandial glucose, which helps cells absorb carbohydrates. In patients with type 1 diabetes, the autoimmune system kills the beta cells incorrectly, and the reason is unclear and the body can not live without insulin. People control their diabetes by carefully calibrating doses of insulin. However, this is almost impossible to match with the precise insulin control obtained from healthy pancreas, so researchers have for decades sought to find a way to replace the missing cells.
When scientists isolated human embryonic stem cells (ES cells) in 1998, they hoped to soar. ES cells are pluripotent, which means that in theory they can be transformed into any of the body's cells, including beta cells. In fact, one of the first studies of researchers was trying to make islet beta cells using ES cells. Later, they tried to use so-called induced pluripotent stem cells (iPS cells) by reprogramming somatic cells into embryoid-like states. Either way, "it turns out to be a very complex job," said Mark McNagnard at Vanderbilt University in Nashville to study pancreatic development.
Several research groups have differentiated stem cells into β-cell precursors that mature when placed in laboratory animals. However, these cells take 6 weeks to become fully functional beta cells, and they are not easy to study in vitro. However, clinical trials began testing their use in patients last month.
