      A genomic study has revealed new insights into the function of anti-Müllerian hormone (AMH) in the context of reproductive biology and fertility. Insights into the physiological, and potentially therapeutic, function were identified based on data from single-cell RNA sequencing, derived from transcriptomic analysis and immunolabeling of antral follicles.

        @debraj The researchers used ovarian cortical xenografts with cotransplantation of engineered endothelial cells to examine the effect of chronic paracrine AMH stimulus on human folliculogenesis. They cotransplanted human ovarian cortex with control or AMH-expressing endothelial cells in immunocompromised mice and recovered antral follicles for purification and subsequent analysis. Overall, 38 antral follicles were observed (19 control and 19 AMH) at long-term intervals, defined as intervals greater than 10 weeks. The researchers found that long-term xenografts showed an accelerated growth rate in the setting of chronically elevated AMH and exhibited a molecular signature indicative of more advanced stages of follicle maturation, including that of luteinization.
