Overview
A bone marrow transplant may use cells from your own body (autologous transplant) or a donor (allogeneic transplant). Since 1968, bone marrow transplant has helped treat diseases such as leukemia, lymphomas, aplastic anemia, immune deficiency disorders, and some solid tumor cancers.
About Bone Marrow Transplant
Bone marrow transplant or stem cell transplant, a procedure of infusing healthy blood-forming stem cells into the body to replace damaged or diseased bone marrow, is needed for patients with certain cancers or other diseases. Bone marrow transplants may use cells from your own body (autologous transplant) or a donor (allogeneic transplant). The purpose of BMT is to transfer healthy bone marrow cells into a patient after their own unhealthy bone marrow has been treated to kill the abnormal cells. Allowing safe treatment of conditions with high doses of chemotherapy or radiation, by replacing or rescuing the bone marrow damaged.
Replacing diseased or damaged marrow with new stem cells
Providing new stem cells, which can help kill cancer cells directly
What is Bone Marrow?
Bone marrow is a soft, spongy tissue that resides in the center of certain bones, including the hip and thigh bones. It contains stem cells, which are the precursors to red blood cells, white blood cells, and platelets. These blood cells have vital functions: red blood cells carry oxygen throughout the body, white blood cells fight infections, and platelets help with blood clotting and wound healing.
The bone marrow is divided into two types: red and yellow. Red marrow is responsible for producing red blood cells, some types of white blood cells, and platelets. Yellow marrow, which is high in fat, can convert into red marrow when the body needs to increase its blood cell production, such as when a person has anemia or after a significant blood loss.
Bone marrow also plays a crucial role in the immune system. The white blood cells it produces are part of the body’s first line of defense against disease and infection. These cells identify and destroy pathogens and also help to create antibodies, which the body uses to fight off future infections.
In addition to its role in blood cell production and immunity, bone marrow is also a critical component in medical treatments. Bone marrow transplants can be used to treat diseases that affect the marrow’s function, such as leukemia and lymphoma. In these procedures, the patient’s diseased marrow is replaced with healthy marrow from a donor.
Despite its soft and spongy nature, bone marrow is a robust and vital part of the human body. Its role in producing blood cells and supporting the immune system makes it essential for our survival. Understanding the function of bone marrow can provide insight into how our bodies work and how diseases can affect this important tissue.
