What is allogenic?
allogeneous directly is translated into the word homologous . Both are adjectives that mean they refer to tissue, bone marrow or blood, in any form of transplantation or transfusion, ie from the same species. These terms are contrasted with autologous , which means the use of one of these tissues from the same person to the same person. A person who acquires his own tissue is an autologous procedure. When allogeneic transplantation is carried out, donated tissue comes from the same species, unlike any other form of animal species (xenograph) or from each other (autolog).
In most cases, tissue, blood or other cell types are transplanted. This still means that before inserting into one body, there must be a certain degree of match that lived in another. Blood donation should also be checked to confirm that it is not contrary to the blood type of the receiver. Rejection of autologous blood transplantation can OCCUR if blood is not fully aligned. This does not always mean that types of blood must beto match exactly. The positive blood could be able to accept most other types of blood, but negative blood can usually only receive negative.
More accurate comparison may be needed for things such as allogeneic bone marrow transplantation or organ transplantation. That is why doctors often often look for a suitable match for bone marrow or organs that people can donate to all or parts such as kidneys or liver. The closer the match, the less likely the rejection. From time to time, suitable matches are produced outside the close family and for certain organs are almost always produced outside the family, such as heart transplantation.
What needs to be understood is whether transplantation or transfusion comes from or comes from the family of man, so long, so long comes from another person, it is allogenic. If it comes specifically fromA person who needs transplant/transfusion is described differently. For example, take a person who cannot have blood transplantation. In this case, the surgeon could decide to collect blood lost during surgery and transfer it to the body of the person. That would be autologous.
Similarly, the collection of bone marrow at birth, usually through the collection of cords, could make people who later developed cancer to choose to use their own pulp. It would be a perfect match. That would not be allogenic, but it would be autologous. Egg collection for later fertilization can also be considered autologous, although after fertilization they would also be allogeneous, containing the genetic material of other persons.
Simply put, a homologous or allogeneous diameter of the same species. The donor may or may not be a close relative. A close comparison of genetics is still very important, but a thnezing relationship. Two things that a homologist cannot be, are me or a member of another kind.
