Correspondingly, miR-155 was induced by vitiligo-associated cytokines in human primary melanocytes and keratinocytes. When overexpressed, miR-155 inhibited the expression of melanogenesis-associated genes and altered interferon-regulated genes in melanocytes and keratinocytes.

IL-36RN is predominantly expressed in keratinocytes but not in fibroblasts, endothelial cells or melanocytes. IL-36RN is also detected in the spleen, brain  av A Julander · Citerat av 2 — the epidermis, which is composed of keratin cells (keratinocytes), it is possible (UV) and visible light by producing a dark pigment (melanin) in the melanocytes.

However, hyperpigmented lesions may develop if a cluster of keratinocytes accumulates an excessive amount of melanin. 2013-11-21 · Although melanocytes require a greater dose of UVR exposure to generate DNA damage equivalent to keratinocytes (Fig. 6A), arsenite concentrations of 1 μM were sufficient to cause retention of UVR-induced DNA damage in keratinocytes (Cooper et al., 2013; Zhou et al., 2011) and melanocytes (Fig. 6 B and C).

Skin from UVB-irradiated C57BL/6 mice receiving 0.4 mg ASA daily by gavage exhibited less inflammation, fewer sunburn cells, and reduced 8-oxoguanine lesions than skin from irradiated control animals.

Conclusions: It could be concluded that vitamin C has a potent effect on melanocytes. Vitamin C affected the melanocytes function and their quantitative productivity, as well as decreasing the cell-cell contact between melanocytes and keratinocytes.

The cytotoxic effects of caulerpenyne, the major secondary metabolite from C. taxifolia, was studied in different in vitro models: skin cells, primary cultures of melanocytes and keratinocytes, immortalized keratinocytes (HaCaT and HESV), and bone marrow cells (hematopoietic progenitors CFU-GM).

Given that melanocytes are in direct contact with keratinocytes in human skin, and that many age‐associated epidermal changes can be attributed to the loss of replicative capacity of keratinocytes (Gilhar et al, 2004), we next examined whether senescent melanocytes could also exert adverse paracrine effects in these cells. Melanocytes are found in the basal layer of the epidermis.

Skin biology and inflammation. Co-culture of Melanocytes with Adipose-derived Stem Cells as a Potential Substitute for Co-culture with Keratinocytes, J-Y.

Keratinocytes form in the deep, basal cell layer of the skin and gradually migrate upward, becoming squamous cells before reaching the surface of the skin over the course of a month. To determine the role of autophagy as a melanosome degradation machinery, we administered several autophagy inducers in human keratinocytes and melanocytes. Our results showed that the synthetic autophagy inducer PTPD-12 stimulated autophagic flux in human melanocytes and in keratinocytes containing transferred melanosomes. A co-culture system of human primary melanocytes and keratinocytes from the same indi- vidual was established.

Melanocytes are branch-shaped, which allows them to transfer melanin to other skin cells, like keratinocytes. Keratinocytes are the most common skin cells that strengthen the hair, nails, and skin.

This volume includes contributions on different cell types relevant in in vitro systems in dermatology such as melanocytes, keratinocytes or fibroblast cultures.

When melanocytes were cocultured with keratinocytes in monolayer or in epidermal reconstructs, they assumed a multidendritic morphology and donated pigment to surrounding keratinocytes. The majority of pigmented cells localized singly within the basal layer of the reconstructs and their dendrites were intimately associated with keratinocyte plasma membranes. Lifeline® offers a number of keratinocytes and melanocytes, including: • Neonatal epidermal melanocytes (primary, secondary, and highly pigmented) • Adult epidermal melanocytes (secondary and highly pigmented) • Neonatal epidermal keratinocytes • Adult epidermal keratinocytes • 10-donor pool of 2014-12-01 · An important function of the skin is to protect an animal's body from external stimuli.
