Human skin cells can create new hair follicles when transplanted into mice.
research Differential sensitivity of epidermal cell subpopulations to β-catenin-induced ectopic hair follicle formation
Sebaceous glands can form new hair follicles when activated, but hair follicle bulges cannot.

The method allows detailed observation of hair tissue structures.
research Structure and Function of the Skin
The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.
research Histological characterisation of the skin of the Paraechinus hypomelas, Brandt, 1836 (Erinaceidae: Eulipotyphla)
Brandt's hedgehog has thick skin on its back and many glands near its nostrils.
research Immunohistochemical analysis of tissue remodelling during the anagen—catagen transition of the human hair follicle
The inner root sheath is vital for hair follicle stability during growth changes.
research Cytokeratin expression in trichoblastic fibroma (small nodular type trichoblastoma), trichoepithelioma and basal cell carcinoma
Trichoblastic fibroma and basal cell carcinoma are similar but different from trichoepithelioma.
research Harnessing the intradermal delivery of hair follicle dermal papilla cell spheroids for hair follicle regeneration in nude mice
Delivering specific cell clusters into the skin can help regrow hair in mice.
research Expression of the Intermediate Filament Keratin Gene,K15,in the Basal Cell Layers of Epithelia and the Hair Follicle
K15 gene is mainly active in the basal layers of hair follicles and epithelia, aiding early skin cell development.
research Existence of trichohyalin-keratohyalin hybrid granules: Co-localization of two major intermediate filament-associated proteins in non-follicular epithelia
Trichohyalin is found in non-hair tissues and works with filaggrin in certain skin areas and conditions.
research Anatomical Mapping and Density of Merkel Cells in Skin and Mucosae of the Dog
Dogs have varying numbers of touch-sensitive Merkel cells in different skin areas, with most in the oral mucosa and facial skin, unrelated to age, sex, breed, or color.
research Faculty Opinions recommendation of De novo production of dermal papilla cells during the anagen phase of the hair cycle.
New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
research Manipulation of stem cell proliferation and lineage commitment:visualisation of label-retaining cells in wholemounts of mouse epidermis
Stem cell behavior varies with stimuli, and lineage changes can happen without affecting stem cell division.
research KERATIN PHENOTYPES IN BASAL-CELL CARCINOMAS OF THE SKIN
Basal cell carcinoma shows keratin patterns similar to hair follicle structures.
research [Hair follicle cell mixture forms hair follicle-like structures after subcutaneous implantation in nude mice].
Implanted human scalp cells can regenerate hair-like structures in mice.
research Locations of synthesis of hair structural proteins in human anagen follicles
Hair structural proteins are synthesized sequentially in specific cells, offering a new way to study hair proteins and defects.
research Potency of implanting microencapsulated human hair dermal papilla cells to induce hair follicle formation
Microencapsulated human hair cells can successfully grow new hair follicles in mice.
research 1323 Human dermal fibroblasts and mast cell populations are altered in hidradenitis suppurativa, with epithelial-mesenchymal-transition signals ameliorated by spleen tyrosine kinase antagonism.
Skin cells and immune cells change in a skin condition called hidradenitis suppurativa, and a certain treatment can improve these changes.
research Heparanase 1: a key participant of inner root sheath differentiation program and hair follicle homeostasis
Heparanase is essential for hair follicle health and inner root sheath differentiation.
research Type II Epithelial Keratin 6hf (K6hf) Is Expressed in the Companion Layer, Matrix, and Medulla in Anagen-Stage Hair Follicles
K6hf is found in specific parts of hair follicles, nails, and tongue, and is linked to hair growth and structure.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research EctopicAtoh1expression drives Merkel cell production in embryonic, postnatal and adult epidermis
Atoh1 expression can create new Merkel cells in the skin.
research Morphological characteristics and notes of the skin in preclinical toxicity assessment
Skin structure complexity and variability are crucial for assessing skin toxicity in safety tests.
research Synchronizing actin and microtubules for axonal branching
Certain proteins help nerve cells branch, and other findings relate to cancer, stem cell behavior, and cell division.
research Detection of Functionally Active Melanocortin Receptors and Evidence for an Immunoregulatory Activity of α-Melanocyte-Stimulating Hormone in Human Dermal Papilla Cells
αMSH may help regulate immune responses in hair follicles and its disruption could lead to hair loss.
