Our results indicate the presence of multiple stem cells in cutaneous epithelium, some with restricted lineages in the absence of major injury. Epidermal stem cells reside in the lower part of the epidermis (stratum basale) and are attached to the basement membrane through hemidesmosomes.Epidermal stem cells divide in a random manner yielding either more stem cells or transit amplifying cells. A., Delwel, G. O., Hulsman, E. H. M. S., Kuikman, I., andSonnenberg, A. Ophthalmol. We summarize here the current knowledge of epidermal SCs of the adult skin.

A distinct germinative epidermal cell population is activated, The question of how stem cells function and are replaced in the growing hair follicle and the role that stem cells in the bulge region of the follicle play in hair production remains somewhat confused.

Human diploid keratinocytes may be divided into three clonal types with differing capacities for proliferation. In adult skin, each hair follicle contains a reservoir of stem cells (the bulge), which can be mobilized to regenerate the new follicle with each hair cycle and to reepithelialize epidermis during wound repair. 49–62, Sonnenberg, A., Calafat, J., Janssen, H., Daams, H., van der Raaji-Helmer, L.

It is estimated that, in 1992, there were 35.2 million cases of significant skin loss (US data) that required major therapeutic intervention. Although the boundaries of the columns cannot be traced to the basal layer in man in the same way as they can in the mouse, the existence of such columns implies some compartmentalization comparable to the EPU of the mouse (. 765–778, Choate, K.

Transcriptionally targeted lentiviral vectors efficiently transduced clonogenic stem/progenitor cells derived from a skin biopsy of a JEB patient, restored normal synthesis of LAM5 in cultured keratinocytes, and reconstituted normal adhesion properties in human skin equivalents transplanted onto immunodeficient mice.

Effect of adenovirus-mediated expression of Sonic hedgehog gene on hair regrowth in mice with chemotherapy-induced alopecia.

We investigated whether non-circular wounds or smaller (≤1 cm) circular wounds could induce early entry of hair follicle stem cells into anagen.

We report that keratinocytes with characteristics of stem cells can be isolated from cultured human epidermis on the basis of high surface expression of beta 1 integrins and rapid adhesion to extracellular matrix (ECM) proteins. The paper also reviews recent data showing that: (i) cultured epidermal autografts bearing melanocytes can be used for the treatment of stable vitiligo; (ii) keratinocytes isolated from other lining epithelia, such as oral, urethral and corneal epithelia, can be cultivated and grafted onto patients suffering from disabling epithelial defects; (iii) keratinocyte stem cells can be stably transduced with retroviral vectors and are therefore attractive targets for the gene therapy of genodermatoses.". Previously, we provided single cell lineage tracing and proliferation history data (based on H2B-GFP label dilution over time) in mouse hair follicles.

While their full function has yet to be determined, numerous studies have implicated their role in homeostatic skin processes. Pract.,8, pp.

They discovered a panel of cell surface markers useful for isolating living hair follicle stem cells, a finding with potential therapeutic implications since isolated stem cells in mice can generate new hair follicles when transplanted to other mice.

Although we found LRCs in both collagen- and scaffold-based OTCs, only the scaffold-OTCs supported long-term survival and regeneration.

We proposed a population deterministic model with symmetric stem cell fate decisions throughout life.

It was assumed that this label was persisting in the stem cells because these cells cycle more slowly than other members of their dependent lineage, i.e., the incorporated precursors dilute more slowly (see also below). NLM

Article  ‘Cultured keratinocyte grafting. In: Research Community (ed) The stem cell, Stembook. Several putative biomarkers have been suggested for identifying murine follicular stem cells; however, human hair follicles have a different pattern of biomarker expression, and follicular stem cell isolation methods have not been established.

Skin and its appendages provide a protective barrier against the assaults of the environment. At present it is clear that the bulge region contains very potent regenerative stem cells that are normally quiescent and, hence, presumably represent a reserve population of cells. Hair follicle stem cells sustain growth and cycling of the hair follicle and are located in the permanent portion of the follicle known as the bulge.

Here we provide data suggesting that in hair follicle stem cells the self-renewing divisions within the niche (bulge) are symmetric with respect to localization of daughter cells near the basement membrane, an important niche component.
