This study found that bikunin is expressed in human keratinocytes and may play a role in regulating keratinocyte function during mitosis or inflammation.

This study used a probabilistic Boolean network model to explore hair follicle cell fate regulation and predicted that varying TGF-β levels, in coordination with BMP and TNF, can influence either apoptosis or cell proliferation during different follicle growth stages.

This study found that bursts of ERK activation in the skin, termed SPREADs, are linked to increased cell division and help synchronize cell cycle progression in living mice.

This study discovered a novel mechanism by which germ stem cells exit their niche in C. elegans, involving thin membranous protrusions from adjacent somatic gonad cells.

This thesis explores the role of the actin cytoskeleton in plant cell growth, highlighting its involvement in signal transduction and the regulation of tip growth in cells like root hairs.

This study found that Sox9 plays a critical role in maintaining radial glial progenitor cells and regulates the timing of their generation of upper-layer cortical neurons.

Substance P helps restore skin thickness and cell renewal when sensory nerves are reduced.

Glycogen helps E. coli cells divide unevenly and organize their contents.

Human epidermal stem cells divide faster than previously thought.

Overexpression of certain genes can shorten hair by disrupting the hair-growth cycle.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This study suggests that high concentrations of minoxidil may prolong the proliferative capacity of keratinocytes, which may partially explain its positive effect on hair growth.

This review discusses the mechanisms, uses, and side effects of conventional synthetic DMARDs, particularly methotrexate, for rheumatoid arthritis, but reports no new clinical findings.

Ovol2 is essential for normal skin and hair regeneration.

This study found that altering CDK4 expression in mice affects the population of keratinocyte stem cells, suggesting a correlation with susceptibility to skin papillomas.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This chapter discusses the concepts of regeneration and homeostasis, noting that in vertebrates, regeneration is limited to certain tissues like liver, blood, and bone.

This study revealed that basement membrane dynamics are crucial to hair follicle development, influencing progenitor cell behavior and cell division patterns in developing mouse hair follicles.

This study found that the Wnt-β-catenin pathway directly promotes TERT expression in both stem and cancer cells, highlighting a mechanistic link between tumorigenesis and pluripotency.

This study found that 4-aminopyridine significantly enhanced skin wound healing by accelerating wound closure, improving skin architecture, and promoting hair follicle neogenesis and tissue regeneration.

In this study, epidermal growth factor (EGF) was shown to increase the length of rat organ of Corti segments containing supernumerary hair cells, with the effect peaking at birth and independent of cell division.

This study found that ethanolic, aqueous, and hydroethanolic extracts of Tridax procumbens inhibited mitosis and caused mutagenic effects on cell division in Allium cepa root meristematic cells.

Alloxan diabetes, methylthiouracil, cortisone, and adrenaline affect how white mice hair follicles use glucose and cystine and their cell division.

This study demonstrates that modeling clone size independently of time offers analytical advantages for understanding cell distribution and mutation frequency in epithelial progenitors, extending applications beyond neutral models.

This study found that the curl in hair is due to the arrangement of different cell types, with shorter paracortical cells inside the curve and longer orthocortical cells outside.

This study found that MYH9 acts as a tumor suppressor in squamous cell carcinomas by stabilizing p53 in the nucleus, suggesting its role in cancer prevention.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

This review assessed the role of scalp hair Survivin protein in individuals with premature graying, exploring its potential involvement in graying-related processes and highlighting its overexpression in autoimmune diseases that may influence the survival of specific immune cell clones.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

This chapter examines how toxins such as inorganic arsenic, dioxin, and bacterial toxins can disrupt the balance of keratinocyte stem cell regeneration and differentiation, affecting skin barrier maintenance.
