Imagine two people are listening to music.

After all, everyone has very different tastes in music.

畢竟每個人對音樂的喜好非常不同，

the exact same medical care and treatment

each of us will have very different needs

Scientists and doctors are constantly researching ways

Stem cells are cells that are undifferentiated,

幹細胞是沒有經過分化的細胞，

meaning they do not have a specific job or function.

stem cells do not have any specific structures or functions.

然而幹細胞沒有任何特殊結構或功能，

to become all other kinds of cells in your body.

就是變成人體中任何一種細胞，

the lining of your intestines every four days.

Stem cells beneath the lining of your intestines

Scientists hope that stem cells could be used

to create a very special kind of personalized medicine

創造出非常特殊的個人化醫療，

in which we could replace your own body parts with,

Using stem cells to replace damaged bodily tissue

使用幹細胞取代損壞的身體組織，

For example, scientists currently use stem cells

Bone marrow is the spongy tissue inside your bones

In leukemia, some of the cells inside your bone marrow

白血病的症狀，是骨隨內的一些細胞

grow uncontrollably, crowding out the healthy stem cells

the blood cells needed by the patient's body.

Adult stem cells or tissue-specific stem cells

在人體器官既有的細胞死亡的時候，

from leftover embryos that are willingly donated

來自剩餘胚胎，通常由生育診所

is called induced pluripotent stem cells.

These are regular skin, fat, liver, or other cells

they, too, can become any kind of cell in the body.

這些幹細胞也能變成人體中任何一種細胞，

製造出新的人體組織進行治療，

科學家透過觀察幹細胞成長組織，

into tissue to understand the mechnanisms

they can not only develop specialized medicine

發展出更專門、為個人量身打造的
