   What is a stem cell in biology?

   • stem cell, an undifferentiated cell that can divide to produce some offspring cells that continue as stem cells and some cells that are destined to differentiate (become specialized). Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants.

   What is stem cell therapy?

   • Stem cell therapy, also known as regenerative medicine, promotes the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. It is the next chapter in organ transplantation and uses cells instead of donor organs, which are limited in supply. Researchers grow stem cells in a lab.

   Where do stem cells come from?

   • There are several sources of stem cells: Embryonic stem cells. These stem cells come from embryos that are 3 to 5 days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.

   What are the characteristics of a stem cell?

   • The classical definition of a stem cell requires that it possesses two properties: Self-renewal: the ability to go through numerous cycles of cell growth and cell division, known as cell proliferation, while maintaining the undifferentiated state. Potency: the capacity to differentiate into specialized cell types.

   幹 細胞 （英語： stem cell ）是原始且未特化的 細胞 ，它是未充分分化、具有再生各種組織器官的潛在功能的一類細胞。 幹細胞存在於所有多細胞 組織 裡，能經由 有絲分裂 與 分化 來 分裂 成多種的特化細胞，而且可以利用 細胞分裂 來產生更多相同的幹細胞。 對哺乳動物來說，幹細胞分為兩大類： 胚胎幹細胞 與 成體幹細胞 ， 胚胎幹細胞 取自 囊胚 裡的 內細胞團 ；而 成體幹細胞 則來自各式各樣的組織。 在成體組織裡，間葉幹細胞與 前體細胞 擔任身體的修復系統，補充成體組織。 在胚胎發展階段，幹細胞不僅能分化為所有的特化細胞- 外胚層、內胚層和中胚層 (參考 人工多能幹細胞 )，而且能維持新生組織的正常轉移，例如血液、皮膚或腸組織。
