Las células madre son células no especializadas que tienen el potencial de convertirse en cualquier tipo de célula del cuerpo.. This makes them a valuable resource for medical research and potential treatments for a variety of diseases. Las células madre se pueden obtener de diversas fuentes., incluyendo embriones, sangre del cordón umbilical, y tejidos adultos.
El origen de las células madre
Las células madre se derivan de la masa celular interna de un blastocisto., which is a very early embryo. La masa celular interna da lugar a todos los tejidos y órganos del cuerpo.. Stem cells are also found in the umbilical cord blood, which is the blood that flows through the umbilical cord from the fetus to the mother.
Fuentes de células madre
Hay dos tipos principales de células madre.: células madre embrionarias y células madre adultas. Las células madre embrionarias se derivan de la masa celular interna de un blastocisto., while adult stem cells are found in various tissues throughout the body. Adult stem cells are more limited in their potential than embryonic stem cells, but they are easier to obtain and less controversial.
Células madre embrionarias
Las células madre embrionarias son pluripotentes, lo que significa que tienen el potencial de convertirse en cualquier tipo de célula del cuerpo.. This makes them a valuable resource for medical research, as they could potentially be used to treat a wide variety of diseases. Sin embargo, embryonic stem cells are also controversial, as they are derived from embryos that are destroyed in the process of obtaining the cells.
Células madre adultas
Las células madre adultas son multipotentes, lo que significa que tienen el potencial de convertirse en un número limitado de tipos de células. Sin embargo, adult stem cells are more readily available than embryonic stem cells, and they are not controversial. Adult stem cells have been used to treat a variety of diseases, incluyendo leucemia, linfoma, y anemia falciforme.
Stem cells are a valuable resource for medical research and potential treatments for a variety of diseases. Sin embargo, the ethical issues surrounding embryonic stem cells have led to a search for alternative sources of stem cells. Adult stem cells are a promising alternative, as they are more readily available and less controversial than embryonic stem cells.
