It is highly unlikely the transplant team will risk the donation. Both the recipient and the donor could be at risk. Methadone does affect bone marrow both by its use and because of why it is being used. High risk behavior including using injectable drugs and unsafe sexual practices while high leaves the possible donor suspect for HIV and other diseases.
While offering bone marrow is a noble gesture, the risk to the patient is high.
Bone marrow is a red compound found at the centre of large bones in the body. It helps the body to make blood cells and have immunity against diseases. A bone marrow donor has a small operation, where a small hole is made in their hip bone. Some bone marrow is removed, under local anaesthetic. This bone marrow is then given to the bone marrow recipient.
Sort of... Assuming there is no GVHD and the bone marrow transplant is successful, a blood test will show what percent of the recipient's blood is their own blood and what percent of the recipient's blood was produced from the donor's bone marrow. If the test comes back ">95%", then the recipient's blood and the donor's blood have become DNA-identical. Interestingly enough, the recipient's hair and saliva remain the same DNA they were born with. Their hair and saliva do NOT change to the donor's DNA. So, the recipient of the bone marrow transplant would then have two DNA's in their body. Neat stuff!
The innermost part of the bone in called the Bone Marrow or inner bone
well bone marrow is a substance that is inside of the bone, so there for bone marrow is part of the skeletal system.
the purpose of the bone marrow is to make up the bone
allogenic
All bone marrow transplants require bone marrow from a donor; the purpose of the transplant is to replace the patient's bone marrow (that no longer works) with some that does work, which clearly cannot come from the patient (since they have none that works). Hence a donor must be used.
Her sister!!
In a procedure called "allogeneic bone marrow transplant," a donor is found whose marrow matches that of the patient.
Autologous = own marrow Allogeneic = transplant from a related (or tissue matched) donor. Syngeneic = transplant from an identical twin.
If it's a blood donor, you don't need to. BMBP'S REPLY-I accept but we are talking about bone marrow transplantation

Bone marrow is a red compound found at the centre of large bones in the body. It helps the body to make blood cells and have immunity against diseases. A bone marrow donor has a small operation, where a small hole is made in their hip bone. Some bone marrow is removed, under local anaesthetic. This bone marrow is then given to the bone marrow recipient.
Either a bone marrow or a stem cell transplant (although these days most stem cell transplants are obtained from blood).
This is bone marrow transplant. A compatible donor should be screen and crossmatch before they can perform the transplant.
There are three types of bone marrow transplant procedure. One of the three is called an Autologous bone marrow transplant. With an Autologous bone marrow procedure, doctors take the persons own bone marrow and freeze it before chemo then reintroduce the marrow into red blood cells after chemo or radiation. The second type is Allogeneic. In an Allogeneic marrow procedure the marrow is taken from a matching marrow donor. The third type is called Umbilical cord blood transplant. With an umbilical cord blood transplant, there can be a wider variety of donor as the cells are still considered immature.
