Investigadores de Mayo Clinic crean sistema más eficaz para reprogramar células madre

Mayo Clinic

Las células madre pluripotentes inducidas son las laboriosas obreras de muchos proyectos de medicina regenerativa y empiezan como células diferenciadas que, a través de la exposición a un complejo conjunto de mezclas genéticas, se reprograman para convertirse en células madre pluripotentes.

Sensitive sensor detects Down syndrome DNA

American Chemical Society (ACS)

According to the Centers for Disease Control and Prevention, Down syndrome is the most common birth defect, occurring once in every 700 births. However, traditional non-invasive prenatal tests for the condition are unreliable or carry risks for the mother and fetus. Now, researchers have developed a sensitive new biosensor that could someday be used to detect fetal Down syndrome DNA in pregnant women’s blood. They report their results in the ACS journal Nano Letters.

Mayo Clinic researchers develop more efficient system to reprogram stem cells

Mayo Clinic

Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails.
