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 study found that loss of the folliculin protein delays transferrin receptor recycling, leading to iron deficiency and suggesting a role in the mechanisms of Birt-Hogg-Dubé syndrome.

This study found that pyramidal neural precursors best grew neurites on matrigel, while neural stem cells differentiated directionally on aligned fibrin, suggesting the importance of biomaterial selection for cell culture.

This study explored the development of GelMet, an electrospun hybrid nanofiber scaffold made from gelatin and PEG methacrylate, which demonstrated strong mechanical properties and effectively supported cell growth in vitro, suggesting its potential for skin tissue engineering applications.

In this study, a collagen sponge with isogenic fibroblasts did not enhance skin graft survival or wound healing in rats, but it did promote re-epithelization, potentially inducing epithelial inclusion cysts.

This theoretical research project proposes the Carnivore Follicular Integrity Framework, suggesting that animal-based diets may support hair follicle stability through various evolutionary and mechanistic pathways.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This study investigated the gene and protein expression differences in early and late feathering chickens, identifying several pathways, like JAK-STAT and WNT, potentially involved in non-Mendelian feather growth regulation.

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

In this study, researchers used embryonic chicken skin as a model to show that perturbing calcium signaling can induce feather bud formation in areas that typically do not form them, highlighting developmental bioelectricity as a crucial yet underexplored layer in tissue patterning.

This overview outlines the latest advancements and challenges in developing three-dimensional scaffolds for biomanufacturing cultured meat, focusing on organizing muscle stem cells to better mimic the structure of traditional meat. Results are not reported in the abstract.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This study reported that supplementing rat hair follicle stem cells with chick embryo extract enhanced their migration and proliferation, possibly promoting differentiation toward Schwann cells.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This study found that the miR-140-y-TCF4 axis regulates the proliferation of goose embryonic dermal fibroblast cells by affecting the Wnt signaling pathway, highlighting its role as a dynamic regulator during skin and feather follicle development.

In this study, in ovo injection of CHIR-99021 promoted the morphogenesis and development of feather follicles in chick embryos by activating the Wnt/β-catenin signaling pathway.

This study found that protein hydrolysates from mealworms, especially those derived using flavourzyme, significantly enhance adipogenic differentiation in 3T3-L1 preadipocytes, suggesting their potential as sustainable ingredients for glycemic control, skin health, and tissue regeneration products.

This study developed a multifunctional core-shell fiber dressing that preserves platelet-rich plasma for 180 days, facilitating sustained growth factor release and improved wound healing.

This study found that human dermal fibroblasts can promote the viability and proliferation of microvascular endothelial cells in vitro, revealing important interactions at play in hair growth.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This review highlights the role of various signalling pathways, particularly the inhibitory BMP pathway, in regulating feather follicle development in poultry and discusses the application of biotechnology for enhancing poultry aesthetics, emphasizing the increasing importance of feather follicles in ice-fresh poultry sales in China.

This study found that the polyurethane-cellulose acetate scaffold containing plasma rich in growth factors enhanced gene expression linked to wound healing compared to controls.

This study developed a prototype pneumatic dual-cell implanter that successfully stacked and implanted cells in tests, reducing hand burden for operators, which may improve alopecia treatments compared to traditional hair transplantation.

This study found that RALF peptides, through liquid-liquid phase separation, form condensates with pectin and other proteins, playing a pivotal role in plant development and stress response regulation.
