United KingdomA study published in iScience has uncovered new insights into female fertility by examining the role of microtubules in ovarian follicle development. Researchers from Japanese institutions, including Waseda and Kyoto Universities, focused on the microtubule-stabilizing protein Camsap3 and its involvement in transzonal projections (TZPs), which are cellular connections between oocytes and granulosa cells. Using Camsap3-knockout (KO) mice, they found that the absence of Camsap3 led to complete infertility and disrupted follicle maturation, particularly during the transition from secondary to antral stages. Super-resolution imaging revealed that over 80% of TZPs contain both microtubules and actin, challenging previous assumptions that TZPs were mainly actin-based. This finding suggests that microtubules play a critical role in granulosa cell-oocyte communication and follicle development.
