Crean cAi??lulas que producen insulina

Investigadores de Estados Unidos han creado cAi??lulas que producen insulina a partir del donante de ADN de un docente con diabetes, que puede unirse para desarrolla terapia celulares personalizadas para la enfermedad.

Mediante un procedimiento de transferencia nuclear celular, los cientAi??ficos obtuvieron cAi??lulas madres a partir de materiales genAi??ticos de un donante adulto de tipo 1, que suele detectarse en niAi??os. El mismo grupo de investigadores, en el aAi??o 2011, consiguiA? cAi??lulas productoras de insulina a partir del ADN de pacientes con diabetes tipo 1, aunque en aquella ocasiA?n las cAi??lulas eran triploides, por lo tanto, no podrAi??an ser utilizadas para terapia.Ai??

En cambio, con las nuevas cAi??lulas diploides obtenidas tienen dos juegos de cromosomas por lo que pueden usarse para desarrollar tratamientos personalizados. Los pacientes con diabetes tipo 1 carecen de cAi??lulas beta, lo que provoca una deficiencia de insulina y por ende altos niveles de azA?car en sangre. Con dicha investigaciA?n se espera que se pueda ayudar a una potencial cura de la diabetes de tipo 1, pero los investigadores reconocen que este es el primer paso.
