This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review discusses the plasticity of stem cell populations and their ability to switch between functions for tissue homeostasis and regeneration, emphasizing environmental and hormonal influences, and reports no new results.

This retrospective study observed that switching from tofacitinib to baricitinib improved hair growth in patients with alopecia areata, particularly for previous non-responders, and noted fewer side effects with baricitinib.

This case report describes a rare instance of Hashimoto thyroiditis evolving into Graves' disease, emphasizing the potential for such transitions and the importance of early diagnosis and treatment.

Switching Janus kinase inhibitors helped some patients with severe alopecia areata regrow hair, but insurance issues can worsen the condition.

This study aimed to evaluate the outcomes of switching between two JAK inhibitors, tofacitinib and baricitinib, in treating alopecia areata, due to the lack of data on their comparative efficacy.

Triamcinolone acetonide injections help regrow hair in alopecia areata patients.

This paper examines factors affecting the stretching setting treatment of human hair and wool, concluding that the intended outcomes can be achieved using their customized testing equipment and technology.

This study found that perming, combing, and stretching human hair lead to damage, as evidenced by a reduction in keratins with molecular weights between 67,000 to 43,000 daltons.

Mechanical stretching can improve or hinder skin regeneration depending on duration.

In this study, the authors found that applying hypobaric pressure to the skin significantly increases the transdermal permeation of large molecules by enhancing diffusion, despite the associated skin stretching and hair follicle enlargement not fully explaining this effect.

This study found that a single instance of acute skin stretching can enhance immune surveillance and improve vaccine delivery by increasing skin permeability and promoting immune cell recruitment without causing tissue damage.

This research found that perming, combing, and stretching cause hair damage, leading to a significant reduction in keratin levels within a specific molecular weight range.

This article discusses the use of scalp stretching techniques to enhance donor hair supply for hair restoration, but it reports no new clinical findings.

This study found that in murine dermis, fibroblast state switching between proliferation and ECM deposition plays a crucial role in tissue architecture and wound healing.

This study found that fibroblast behavior switching between proliferation and ECM deposition is vital for dermal architecture, where cell migration is primarily important for tissue repair during wound healing.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This source reviews current understanding of fibroblast lineage differentiation and its role in wound healing, highlighting the potential to reprogram adult cells for scar-free repair by emulating fetal-like regenerative states.

This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.

In this study, researchers found that ritlecitinib, a JAK3/TEC inhibitor, significantly improves hair regrowth, quality of life, and psychological well-being in patients with severe alopecia areata who had inadequate or no response to baricitinib, a JAK1/2 inhibitor.

This paper presents a case where alopecia was associated with the use of escitalopram and improved after switching to duloxetine, alongside a literature review of antidepressant-related alopecia.

This study demonstrates that polarized second harmonic generation imaging effectively monitors wool fiber stretching, revealing significant structural changes in keratin alignment that improve textile performance.

In this study, patients with epilepsy who switched from immediate-release to extended-release divalproex sodium did not experience significant changes in seizure frequency, but most preferred the new formulation due to a subjective decrease in tremor during daily activities.

This study by Pérez-Oliva et al. explored how Mahogunin Ring Finger-1 (MGRN1) affects melanocortin-1 receptor (MC1R) signaling, suggesting that MGRN1 competitively inhibits Gαs binding to MC1R, influencing pigment production.

In this study, 93% of patients with inflammatory arthritis remained on the adalimumab biosimilar ABP 501 for 24 weeks after switching from the originator, with some switching back due to adverse reactions or reduced effectiveness.

This study found that using Dexon sutures led to significantly larger postoperative stretching and scar width compared to Prolene in patients undergoing scalp surgery for androgenetic alopecia correction.

This study suggests that using sebaceous glands from rat tail skin samples may effectively capture hair follicle stem cells, potentially aiding skin regenerative medicine when available tissue is limited.

The researchers reported that yak hair fibers undergo macromolecular conformational changes and partial slippage of macromolecules during stretching, confirming this as the main stretching mechanism when the stretching ratio is large.

This study found that cardiac fibroblasts significantly enhance the maturation of neonatal mouse and human embryonic stem cell-derived cardiomyocytes, suggesting a pivotal role in postnatal heart development and disease.

This case report describes a 40-year-old man whose vitiligo and psoriasis responded favorably to ixekizumab after experiencing vitiligo onset and psoriasis relapse during adalimumab treatment.
