A research team at Kyoto University has discovered STAG3-cohesin, a new mitotic cohesin complex that helps establish the unique DNA architecture of spermaotogonial stem cells (SSCs), the stem cells that give rise to sperm. This “DNA organizer” is crucial for sperm production in mice: without STAG3, SSCs cannot differentiate properly, leading to a fertility problem. In humans, the researchers found that STAG3 is highly expressed in immune B cells and in B-cell lymphomas (a type of blood…
