Bone marrow harvest

Doctors use a needle to extract stem cells from liquid bone marrow, often from the hip bone but sometimes from other locations like the chest bone.
Peripheral blood stem cell (PBSC) collection
This is now a widely used method. It involves stimulating the body to release stem cells into the bloodstream through medications. The stem cells are then collected using a machine similar to that used in blood donation.

While some donors might experience discomfort or fatigue after the procedure, most people can regenerate the harvested bone marrow within a month. For the donor, the process is relatively simple. For the recipient, a bone marrow transplant can be life-saving.
If you would like to help people in need of a stem cell transplant, consider joining a registry like the Buddhist Tzu Chi Stem Cells Center. The group is available for consultations and holds seminars on developments in bone marrow transplant procedures.
骨髓收集
醫生使用針筒來取出骨髓液中的幹細胞，通常是從髖骨的位置取，但有時也會從其他地方（像是胸骨）抽取。
周邊血液幹細胞移植
這是現在廣泛使用的方法。其涉及透過藥物來刺激身體釋放幹細胞至血液中。接著再透過與類似於捐血所使用的機器來收集幹細胞。
雖然一些捐贈者在術後可能會經歷一些不適或疲勞，但大多數人在一個月內被收集的骨髓就會再生了。對捐贈者而言，這個過程相對簡單。而對受贈者而言，骨髓移植可以挽救生命。
如果你想要幫助需要幹細胞移植的人們，考慮在像是慈濟骨髓幹細胞中心登記吧。這個組織提供諮詢，並且會舉辦骨髓移植手術發展的研討會。
