Storage of stem cells on stem cells is a technique that involves taking blood stored in the umbilical cord and storing it in a bank, using stem cells for future research or treatment.
The concept of storage of umbilical cord blood cells is based on the fact that these cells contain stem cells that can be used for treatment or research.
Stem cells (or primary or primary cells or cells of origin) have the capacity to divide, reproduce and regenerate, they are able to form an adult cell and their importance comes from their ability to form n Any type of specialized cell; Neurons and skin cells, so that they can be used in treatment.
Stem cells are the gross body block, cells that have an unlimited ability to divide and multiply and that can differentiate and pass to any type of cell, such as muscles, nerves or bone marrow.
The stem cell is divided to give new cells and these remain stem cells as the parent cell, or differentiate into a cell with specific properties, such as a neuron or a muscle cell, and among the cells of the body.
Physicians can obtain stem cells from several sources, including embryonic cells produced five days after in vitro fertilization of the egg.This type of cell is limited to the treatment of eye diseases such as degeneration macular, bone marrow in adults, umbilical cord
Current scientific evidence indicates that umbilical cord blood stem cells can be used to treat some cases of leukemia (white blood cell carcinoma). After chemotherapy and irradiation, they have completely eliminated bone marrow cells, The body needs cells to produce new bone marrow, and the stem cells can be used as a source.
Although this therapeutic option is a good alternative to the transfer of bone marrow cells from another donor, the success of cord blood stem cells in the treatment of other diseases does not. has not been proven yet.
Cord blood banks are divided into two types:
Public Banks: It follows state or research institutions or universities Parents donate umbilical cord blood for stem cell research After blood donation, parents can no longer afford it. 39, get in the future.
Private banks: Private banks of umbilical cord blood, in which stem cells are stored in the blood of the umbilical cord of a person and kept in his name. At his disposal, where he can get them in the future when he wants, and for the treatment of a family member, for example. This service is provided for a specific amount, including the costs of collecting and storing samples in subsequent years.
In contrast, the technique of storage of stem cells in cord blood is criticized, including:
The amount of stem cells obtained from the umbilical cord is not sufficient for treatment.
The results of studies that say this technique has been successful are flawed and it is unclear how treatment can help. Adults may render unusable the storage of umbilical cord blood, since stem cells can be obtained at any time from the infected child for treatment.
