Endosomes deliver ceramide phosphoethanolamine with unique acyl chain anchors to the cleavage furrow during male meiotic cytokinesis

This study identifies Ceramide phosphoethanolamine (CPE) and its delivery via Rab7-positive endosomes as essential for male meiotic cytokinesis.

Cytonemes with complex geometries and composition extend into invaginations of target cells

The paper uses electron microscopy to reveal structural details of cytonemes in Drosophila, showing their variable diameters and contents, including ER, mitochondria, and ribosomes.

Cellular heterogeneity of the LH receptor and its significance for cyclic GMP signaling in mouse preovulatory follicles

This study investigates the cellular localization of LHR and NPR2 in mouse preovulatory follicles and suggests that LHR-expressing cells signal to neighboring cells to inactivate NPR2.

Three-dimensional organization of transzonal projections and other cytoplasmic extensions in mouse ovarian follicles

The paper examines the three-dimensional structure of transzonal projections and other cytoplasmic extensions in mouse ovarian follicles using serial section electron microscopy, revealing their branching, gap junction formation, and interactions with oocyte microvilli.
