This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This review outlines the potential of using human pluripotent stem cells for hair follicle bioengineering, detailing current HF morphogenesis and cycling knowledge, various cell sources, and strategies using iPSCs, while discussing the challenges and prospects for therapeutic use in addressing hair loss.

In this viewpoint, researchers discussed the possible role of the developmental origin of scalp dermis in influencing the specific pattern of hair follicle miniaturization seen in male pattern hair loss, noting that frontal follicles are more susceptible while occipital follicles remain largely terminal.

This study reported that an HS-associated NCSTN mutation in iPSC-derived skin organoids led to altered hair follicle stem cell differentiation and increased expression of proteins linked to HS inflammation.

This study found that skin organoids derived from iPSCs with an HS-associated NCSTN mutation showed defects in hair follicle stem cell differentiation and increased expression of inflammatory proteins related to hidradenitis suppurativa.

This study found that dysregulation of the DNA damage response in stem cells is a common factor of aging, affecting tissues like the skin, brain, kidneys, and intestine.

This study found that carefully engineered hydrogels and asymmetric morphogen gradients facilitated the formation of anatomically relevant skin organoids from iPSC-derived EBs, improving pigmentation and hair follicle generation.

This article presents Stemson Therapeutics' development of a stem cell-based approach to generate new hair follicles for treating hair loss, which remains in preclinical stages without tested human results.

QIA-64 software can measure straight wire lengths accurately but needs improvement for curved wires and width measurements.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

The researchers reported that iPSCs derived from Sendai virus reprogrammed blood cells can mature into functional keratinocytes for up to 60 days, potentially offering new approaches for DEB treatment.

This study found that long-term hair follicle stem cells originate from embryonic progenitor cells in a niche with reduced Wnt/β-catenin signaling, which is essential for their specification.

This study found that human hair follicles can be used to generate induced pluripotent stem cells, which can then efficiently differentiate back into keratinocytes.

This review discusses the potential of using human pluripotent stem cells to generate new hair follicles, though practical challenges remain before it can be applied for hair restoration.

This study found that human iPSC-derived dermal papilla precursor cells can regenerate hair follicle structures, offering a potential new treatment approach for permanent alopecia.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

In this review, researchers evaluated sericin-based drug delivery systems for antimicrobial, anticancer, and neurodegenerative treatments, highlighting its potential benefits and challenges related to molecular variability and formulation stability, suggesting future focus on optimizing extraction and integration with advanced biomedical technologies.

In this study, pediatric pemphigus was found to have a chronic but mostly benign progression, with initial remission from corticosteroids typically requiring additional immunomodulators for long-term control, and the authors advocate for using rituximab in these cases.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

In this research, experienced clinicians noted inconsistency in the reproducibility of the commonly used Hamilton-Ludwig scales for assessing pattern hair loss severity in photographic assessments, leading to the proposal of a new 5-point scale for staging female hair loss.

In this study, Smad4 deletion in satellite cells hindered skeletal muscle regeneration in adult mice and did not enhance regeneration in aged mice, indicating Smad4's crucial role in muscle repair.

In this study, researchers found that the microRNA profiles of induced pluripotent stem cells (iPSCs) derived from different adult cell types are largely similar, although each line exhibits some unique gene expression, distinct from both their cells of origin and embryonic stem cells.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.
