Kök hücreler vücutta herhangi bir hücre tipine dönüşme potansiyeline sahip, uzmanlaşmamış hücrelerdir.. This makes them a valuable resource for medical research and potential treatments for a variety of diseases. Kök hücreler çeşitli kaynaklardan elde edilebilir, embriyolar dahil, göbek kordonu kanı, and adult tissues.
Kök Hücrelerin Kökeni
Kök hücreler blastosistin iç hücre kütlesinden elde edilir, which is a very early embryo. İç hücre kütlesi vücudun tüm doku ve organlarını meydana getirir.. 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.
Kök Hücre Kaynakları
İki ana kök hücre türü vardır: embriyonik kök hücreler ve yetişkin kök hücreler. Embriyonik kök hücreler blastosistin iç hücre kütlesinden elde edilir., 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.
Embriyonik Kök Hücreler
Embriyonik kök hücreler pluripotenttir, bu da onların vücuttaki herhangi bir hücre tipine dönüşme potansiyeline sahip oldukları anlamına gelir. This makes them a valuable resource for medical research, as they could potentially be used to treat a wide variety of diseases. Fakat, embryonic stem cells are also controversial, as they are derived from embryos that are destroyed in the process of obtaining the cells.
Yetişkin Kök Hücreler
Yetişkin kök hücreler multipotenttir, bu da sınırlı sayıda hücre tipine dönüşme potansiyeline sahip oldukları anlamına gelir. Fakat, 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, lösemi dahil, lenfoma, and sickle cell anemia.
Stem cells are a valuable resource for medical research and potential treatments for a variety of diseases. Fakat, 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.
