The paper investigates the cell and molecular origins of the primate ovarian reserve using rhesus macaques, identifying PG2 cells as the primary source of primordial follicles and describing the recruitment of fetal theca cells for hormone production.

This study uses single-nuclei RNA-seq and spatial transcriptomics to analyze human sacrococcygeal teratomas, revealing cellular heterogeneity and X-chromosome inactivation patterns linked to sex bias.

This study validates the differentiation of rhesus macaque primordial germ cell-like cells (rPGCLCs) using transplantation into adult gonadal niches, showing they commit to late PGCs and spermatogonia-like cells but not ENO2-positive spermatogonia.
