This review discusses the unique features of fetal wound healing that may enable scarless repair and reports no new experimental findings.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

This study reported that the absence of Lsh in skin led to significant epidermal hyperplasia and altered gene expression, suggesting its crucial role in regulating epidermal proliferation, differentiation, and wound healing.

This study found that late embryonic skin injuries can regenerate multiple tissue types, but this ability is hindered postnatally due to fibroblast-driven hyperinnervation, which can be mitigated to enable regeneration.

This article discusses the unique regenerative healing process in fetal skin that can occur without scarring, highlighting potential therapeutic targets to reduce fibrosis in postnatal wound healing.

This review discusses the role of microRNAs in skin function and potential therapeutic applications, emphasizing their importance in wound healing and disease management, though it reports no new experimental findings.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This comprehensive review suggests that CD44 signaling plays a significant role in post-natal skin wound healing and scar formation, with potential for therapeutic approaches targeting CD44 to shift from fibrotic scarring towards regenerative healing, including wound regeneration and hair neogenesis.

This study demonstrated that disrupting sonic hedgehog signaling, using cyclopamine, significantly impaired wound healing in a mouse model, suggesting its crucial role in postnatal tissue repair.

This review discusses the roles of key developmental signaling pathways in mammalian skin repair compared to skin development, and suggests these insights could lead to better wound healing therapies, but it reports no new findings.

Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.

This article discusses the development of skin patterns during embryogenesis and postnatal life, linking them to genetic, environmental, and mathematical factors, but presents no new empirical findings.

This study found that MRL/MpJ mouse dorsal skin wounds heal with similar scar formation and collagen deposition as C57bl/6 and Balb/c mice.

Fetuin-A helps wounds heal without scars by promoting cell movement.

This study successfully developed a reproducible mouse model demonstrating fetal scarless wound healing, which may provide insights for minimizing scarring in adults.

This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This study found that overexpression of sPLA2-IIA in homozygous mice resulted in cyclic alopecia, a halt in hair follicle cycling, and impaired wound healing due to complete loss of hair follicle stem cells.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

This study found that ILK/ELMO2 complexes in epidermal keratinocytes are selectively activated by epidermal growth factor to induce cell migration, unlike with other growth factors.

This study found that FZD2 is crucial for hair follicle formation and postnatal growth in mice and has a novel role in regulating early epidermal development, including stratification and cornification.

This study found that protein extracts from embryonic skin can induce hair follicle neogenesis in mice by activating insulin/IGF signaling in adult fibroblasts.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.
