research Hairless triggers reactivation of hair growth by promoting Wnt signaling
The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.
research Feather arrays are patterned by interacting signalling and cell density waves
Feather patterns in birds are shaped by signaling interactions and cell movements, with EDA/EDAR crucial for pattern formation.
research Stem Cell Heterogeneity and Plasticity in Epithelia
Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
research Hormesis and medicine
Low doses of some substances can be beneficial, while high doses can be harmful or toxic.
research The Chicken Frizzle Feather Is Due to an α-Keratin (KRT75) Mutation That Causes a Defective Rachis
A mutation in the KRT75 gene causes frizzle feathers in chickens.
research Stem cells in tissues, organoids, and cancers
Stem cells are crucial for tissue growth, cancer treatment, and disease modeling, but challenges remain in clinical use.
research Immune deficiency–related enteropathy-lymphocytopenia-alopecia syndrome results from tetratricopeptide repeat domain 7A deficiency
A deficiency in the TTC7A gene causes immune problems, gut issues, and hair loss.
research Compartmentalized organization: a common and required feature of stem cell niches?
Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.
research Hair follicle stem cell cultures reveal self‐organizing plasticity of stem cells and their progeny
The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.
research DKK1 Mediated Inhibition of Wnt Signaling in Postnatal Mice Leads to Loss of TEC Progenitors and Thymic Degeneration
Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.
research Compartmentalized Epidermal Activation of β-Catenin Differentially Affects Lineage Reprogramming and Underlies Tumor Heterogeneity
Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.
research BLIMP1 Is Required for Postnatal Epidermal Homeostasis but Does Not Define a Sebaceous Gland Progenitor under Steady-State Conditions
BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.
research Principles and mechanisms of regeneration in the mouse model for wound‐induced hair follicle neogenesis
Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.
research Live imaging of stem cells: answering old questions and raising new ones
Live imaging has advanced our understanding of stem cell behavior and raised new research questions.
research The Mesenchymal Niche of the Hair Follicle Induces Regeneration by Releasing Primed Progenitors from Inhibitory Effects of Quiescent Stem Cells
The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.
research Glutamate transporter Slc1a3 mediates inter‐niche stem cell activation during skin growth
The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.
research Apoptotic cells represent a dynamic stem cell niche governing proliferation and tissue regeneration
Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.
research Suppression of Wnt/β-catenin signaling by EGF receptor is required for hair follicle development
Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.
research Stem Cells in Dermatology and Anti-aging Care of the Skin
Using defensins to activate stem cells may improve skin aging signs without causing inflammation.
research Deciphering principles of morphogenesis from temporal and spatial patterns on the integument
The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.
research Activated Hair Follicle Stem Cells and Wnt/β-catenin Signaling Involve in Pathnogenesis of Sebaceous Neoplasms
Abnormal activation of hair follicle stem cells and Wnt/β-catenin signaling contributes to sebaceous neoplasms.
research Capturing Stem Cell Behavior Using Intravital and Live Cell Microscopy
Stem cells are more dynamic and adaptable than previously believed.
research Molecular functional analyses revealed essential roles of HSP90 and lamin A/C in growth, migration, and self-aggregation of dermal papilla cells
