New Intermediate Embryonic Stem Cell Type: A Breakthrough in Regenerative Medicine and Reproductive Technology

A team led by UT Southwestern has developed a new type of embryonic stem cell, termed "XPSCs," from mice, horses, and humans. These cells can contribute to chimeras and create precursors to sperm and eggs, opening up new possibilities in basic biology, regenerative medicine, and reproductive technology. XPSCs bridge the gap between naïve and primed pluripotency, offering potential advancements in organ development, infertility treatments, and the preservation of endangered species. This discovery marks a significant step forward in stem cell research and its applications.
