This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse 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 provides new insights into the identification and expression patterns of miRNAs in wool follicles, which could improve understanding of wool follicle development in sheep.

This study concluded that hair follicle hyperplasia found in pseudolymphomatous folliculitis can also occur in genuine cutaneous lymphomas, potentially as a coincidental result of underlying pathological processes.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This study reports that milk goats exhibit significantly more differentially expressed genes related to hair follicle cycling across different months compared to cashmere goats, especially in December.

This study identified and characterized several long noncoding RNAs in Cashmere goats, revealing complex regulatory roles in hair follicle development and growth, particularly within the Wnt signaling pathway.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This study found that intact pilosebaceous units were more effective than truncated hair follicles at regenerating a multilayered epidermis in a de-epidermalized dermis in vitro.

This study found that lncRNA-000133 may play a role in secondary hair follicle reconstruction and cashmere fiber growth in goats, potentially through its interaction with the methylation of its regulatory region and dermal papilla cells.

This study found that PEGylation of nanoparticles enhances their penetration into hair follicles, with higher molecular weight PEG resulting in deeper follicular delivery.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

This study suggests that the long noncoding RNA H19 helps dermal papilla cells maintain their hair follicle-inducing ability by activating the Wnt signaling pathway, potentially offering a therapeutic target for androgenetic alopecia.

This study found that epidermal melanocytes can regenerate hair follicles, whereas non-cutaneous or dermal melanocytes cannot, suggesting two distinct melanocyte lineages with potential implications for melanocyte-related diseases.

This study found that while the EtOAc fraction of Centella asiatica had the highest antioxidant activity, it was toxic to human follicle dermal papilla cells, but the EtOH crude extract promoted hair growth by enhancing VEGF expression.

In this study, nondermal-derived CD34+ cells from adult peripheral blood were found to enhance wound healing and contribute to hair follicle neogenesis and skin regeneration.

This study explored the spatial variation of THFD in cashmere goats and identified four genes associated with it, offering insights that could aid in the development of THFD genes for these animals.

This article describes a modified follicular unit extraction technique using a reverse rake scalp elevator, which may reduce follicular transection rates in hair transplantation from the lower occipital donor region.

This review discusses hair follicle organoids as emerging models for studying hair biology and disorders, emphasizing their promise for bridging basic research and clinical applications, but reports no new results.

This study found that PGRP-S expression in mouse epidermis is specific to certain hair follicle epithelia, depending on the skin region, and can be transiently induced in flank skin hair follicle epithelium after exposure to Staphylococcus aureus, suggesting a role in environmental surveillance.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.
