This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This review discusses the roles and mechanisms of Wnt signaling in embryonic and adult stem cells and its association with cancers, and reports no new experimental findings.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.

This review examines the interaction between hedgehog and Wnt/β-catenin signalling in hair follicles and basal cell carcinoma, linking Hh pathway inhibition to both tumor regression and alopecia.

This discussion explores advances in intravital imaging for visualizing stem cells, highlighting key discoveries and potential future developments; it reports no new experimental results.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.
