Generating gametes from nonreproductive tissues could help overcome infertility. Previous studies have successfully transformed stem cells into viable oocytes through cellular reprogramming. Scientists at Oregon Health & Science University (OHSU) developed a method to derive them from skin cells via somatic cell nuclear transfer (SCNT), unlocking a mechanism that blends mitosis and meiosis. Now, the researchers have taken another step forward by generating fertilizable eggs from human skin cells.

Stem cell implantation is a step closer to becoming the next strategy against Parkinson's disease. Two clinical trials, one in phase I and the other in phase I/II, have demonstrated their safety and potential to restore dopamine production in the brains of patients with this currently incurable neurodegenerative condition. The number of participants in the study is still small, and further research is needed to demonstrate the clinical benefits of these cell therapies.

Six main cell types form glioblastomas, the most aggressive brain cancer due to its high rate of recurrence. Of these six, quiescent cancer stem cells are responsible for resistance to therapy and the reappearance of the tumor, according to a study that identified the six groups and highlighted the importance of these stem cells for the design of more effective therapies.
