This review explores the potential use of plucked hair follicles in regenerative medicine and diagnostics but presents no new research findings.

The article concludes that studying how skin forms is key to understanding skin diseases and improving regenerative medicine.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This study on Indian dromedary camel breeds investigated the KRTAP7 protein, finding all four breeds shared an identical gene sequence, with 13 phosphorylation and glycosylation sites influencing hair characteristics, alongside predicted interactions with other biosynthesis-related proteins.

This review discusses how stem and progenitor cells communicate to synchronize their differentiation responses, highlighting the challenges in identifying these mechanisms and surveying new technologies that may overcome these obstacles.

This review explores the challenges of treating chronic wounds and highlights regenerative medicine as a promising approach, emphasizing the roles of growth factors, stem cell therapies, and novel regenerative treatments in improving wound healing and tissue regeneration.

This study presents evidence that hair matrix progenitors and the enzyme Stearoyl CoA Desaturase 1 may play a role in maintaining the dermal papilla niche via autocrine Wnt and paracrine Hedgehog signaling in mice.

This study reviewed and reclassified 37 cases of primary scarring alopecia using histological methods to achieve more accurate diagnoses within subtypes like lupus erythematosus and lichen planopilaris.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

This study found that the main structural proteins of tree frog toe pads, which aid in their adhesive properties, are alpha keratins that have evolutionary origins in early tetrapods.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

This study explains how the development of keratin-associated proteins in embryonic epidermis is crucial for forming protective barriers in vertebrates, enabling them to adapt to terrestrial environments.

This study found that hypothermically stored amniotic membrane grafts promoted greater tissue regeneration, including basket-weave collagen matrix and follicle formation, compared to dehydrated amnion/chorion meshed grafts in a rat wound model.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.

Only Deomyinae rodents can regenerate complex tissues.

In this study, the researchers found that mammalian hair likely evolved through the adaptation of existing structural proteins, as similar cysteine-rich α-keratins were identified in chicken and lizard genomes, suggesting pre-mammalian origins.

The researchers reported that scaffoldin, a protein identified in chicken embryos, likely plays a role in forming periderm granules and contributes to the soft cornification of embryonic epidermis.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

This study observed that during the postnatal development of gray short-tailed opossums, skin transitions from facilitating gas exchange through a dense capillary network at birth to supporting thermoregulation, with significant changes in skin thickness and structure occurring by 35 days old.

In this study, extracellular vesicles derived from amniotic fluid stem cells enhanced fetal lung development in models of pulmonary hypoplasia, showing promise for therapeutic application.

This study found that the Florida worm lizard has lost certain genes associated with claw development, which are present in other lizard species with claws, suggesting a link between the evolution of their limbless body and the loss of claw-related genes.

Mouse embryos can develop in chick embryos, but they grow smaller with some organ issues.

In this study using a rat full-thickness burn model, the amnion bilayer dressing showed better healing and skin recovery than the standard protocol, including quicker complete healing and restored skin appendages.
