This study found that excess vitamin A in organotypic cultures of embryonic mouse skin led to abnormal hair follicle development and glandular metaplasia, unlike in untreated controls that showed normal differentiation.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

In this chicken embryo study, E40 hemp seed callus-derived exosomes counteracted DHT-induced inhibition of hair follicle development, suggesting potential for alopecia treatment and hair follicle regeneration.

This summary reports that γδ T cells play a role in regulating hair follicle formation during wound healing in adult skin.

In this study of mouse embryos, the researchers found that the expression of the Lhx2 gene plays a significant role in wound healing and may promote scar formation in later stages of development.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

In this study, researchers observed that knocking down the LPA 4 receptor in zebrafish embryos led to vascular and lymph vessel development abnormalities, including edema and decreased heartbeats.

This study introduces genital sex differentiation parameters (GSDP) to analyze sexual differences in external genitalia and perineum development in mice, revealing varied sensitivity to androgen inhibition in genital structures.

This study found that Eda and activin A regulate Foxi3 expression, which may contribute to the development of hypohidrotic ectodermal dysplasia by affecting Foxi3 activity in ectodermal appendages like hair and teeth.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

This study identified a critical NF-κB-LHX2-TGFβ2 signaling pathway essential for primary hair follicle development in mice, revealing new insights into the underlying mechanisms of morphogenesis.

This study found that misexpression of Hoxc8 in mice led to ectopic mammary development and suggests Hox genes may play crucial roles in the regional specification and initiation of cutaneous accessory organs.

This study found that the corneal epithelium differentiation program can proceed independently of lens formation, suggesting the corneal program is the default in eye development.

This review covers the history and development of CRISPR-Cas9 technology, highlighting its groundbreaking applications and the ethical concerns surrounding its use in human germline editing.

This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

This study found that gene-regulatory interactions among parental alleles contribute significantly to heterosis in early stages of maize development, with many differentially expressed genes showing non-additive expression in hybrids.

This study found that maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This study found that K79+ keratinocytes migrate outward to help form the hair follicle lumen both during development and adult regeneration, revealing a novel mechanism of hair follicle formation in mice.

At the 21st Royan International Stem Cell Congress, researchers highlighted the growing integration in regenerative medicine, emphasizing advances in pluripotency, AI applications, and bioengineering for the development of accessible stem cell therapies.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This study identified that the Wave complex proteins ABI1 and Wave2 play a crucial role in regulating epidermal shape and growth during skin development, notably influencing SOX9 expression and Wnt signaling pathways.

This research observed that the skeletal abnormalities in Noggin null mice varied based on genetic background, and identified haploinsufficiency leading to joint fusions, similar to human conditions associated with NOGGIN deficiency.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

This review explores the potential of small molecules to activate the Wnt/β-catenin signaling pathway in treating diseases and reports no new experimental findings.

This study found that over-expression of thymosin beta-4 in transgenic mice accelerated wound healing and hair growth, but did not affect tumor progression despite stimulating tumor metastasis.
