What is the difference between red blood cells and bone marrow transplantation?

summary

A few days ago, I heard that a distant relative had leukemia and needed bone marrow transplantation. Then, what's the difference between dry red blood cells and bone marrow transplantation? Let's talk about it.

What is the difference between red blood cells and bone marrow transplantation?

The first difference is that the principle of hematopoietic stem cell transplantation is the same as that of bone marrow transplantation, but the way of collecting hematopoietic cells is different. The majority of hematopoietic stem cells exist in bone marrow, bone marrow transplantation is to extract bone marrow from the bone marrow cavity through bone marrow puncture, and then collect hematopoietic stem cells into the patient's body. The treatment of leukemia is now more umbilical cord blood hematopoietic stem cell transplantation, but it should be noted that as long as the matching is appropriate, transplantation can be carried out, mainly when the related donors are related, the effect will be better.

Second, stem cell transplantation is to promote the release of hematopoietic stem cells from bone marrow to blood, and collect hematopoietic cells from peripheral blood through blood cell separator. In order to perform bone marrow transplantation, voluntary donors need local anesthesia, and drill holes in the iliac bone several times to extract hundreds of ml of bone marrow mixture.

The third difference is that stem cell transplantation only needs to collect blood from the volunteers' veins, enrich it by machine, and transfuse the blood back to the human body. It only needs 50 ml of stem cells. Due to the balance of the total amount of stem cells in and out, the donor will not have circulatory disorder after collection, which is very safe for the human body. At present, hematopoietic stem cell transplantation (HSCT) is used in the transplantation operations provided by 307 donors. In order to prevent confusion, the names of bone marrow transplantation, bone marrow donation and bone marrow bank are still used.

matters needing attention

The treatment of leukemia is mainly based on their own situation, such patients must adjust their mood, but also pay attention to life and daily diet, mainly according to the guidance of doctors.
