Is bone marrow or blood drawn for bone marrow transplantation

summary

Although we have heard of bone marrow transplantation and know that bone marrow transplantation needs hematopoietic stem cells for surgery, many people may have a lot of doubts. Now let's talk about whether to draw bone marrow or blood for bone marrow transplantation.

Is bone marrow or blood drawn for bone marrow transplantation

First, injection is given to the donor to mobilize the hematopoietic stem cells into the peripheral blood, then the hematopoietic stem cells are isolated from the donor's blood, and other blood is transfused back to the body. It seems that there are bone marrow transplants from Taiwan and Hong Kong.

Second: when doing bone marrow transplantation, the patients are injected with bone marrow hematopoietic stem cells, which come from bone marrow. Now the method of extracting bone marrow hematopoietic stem cells is to extract the hematopoietic stem cells released from bone marrow into the blood instead of directly extracting bone marrow.

Third: in peripheral blood stem cell transplantation, the donated blood is pumped out and then flows through the cell separator. After the stem cells are picked out, the blood is then transported back to the donor. This method can avoid the pain of bone marrow puncture and minimize the impact of transplantation on donors. In addition, this process does not require anesthesia, much like blood donation.

matters needing attention

At present, many hospitals take blood for bone marrow transplantation, so it will also make many people avoid the simple and painful process of direct puncture from bone marrow. So if you want to contribute, you can donate with confidence.
