The researchers found that melanocytes are more resistant to UVR-mediated DNA damage than keratinocytes. They also found that both melanocytes and keratinocytes are sensitive to arsenic. However, if there is enough DNA damage generated by UVR in either cell type, then both are susceptible to arsenic-mediated DNA repair inhibition.

They produce the pigment melanin, which gives the skin color. Melanocytes are also the cell of origin for melanoma, which is most commonly caused by exposure to UV radiation. Recent Studies Using Lifeline® Keratinocytes and Melanocytes The researchers found that melanocytes are more resistant to UVR-mediated DNA damage than keratinocytes. They also found that both melanocytes and keratinocytes are sensitive to arsenic.

Each epidermal melanocyte is associated with a group of neighbouring keratinocytes (keratin -synthesizing epidermal cells) into which its dendrites transfer pigment. This structure is known as an epidermal melanocyte unit. The melanin produced by melanocytes is of two kinds: dark brown eumelanin and pale red or yellowish phaeomelanin. ASA reduced UVB-induced 8-oxoguanine and cyclobutane pyrimidine dimers in Melan-A melanocytes and HaCaT keratinocytes. 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. Melanocytes and keratinocytes work together in protecting the skin from UV damage when keratinocytes a.

Once mature and in place, melanocytes produce melanin, the pigment responsible for skin colour, which is exported to the surrounding keratinocytes (each melanocyte is connected to roughly 40 keratinocytes) in grain-like structures known Melanocytes and keratinocytes establish a complex intercellular dialog required for skin photoprotection. 2D co-culture systems, where these two cell types share the same medium, have been widely cultured keratinocytes and melanocytes were stained for pancytokeratin to distinguish keratinocytes.

Melanocytes and keratinocytes attached and proliferated on both acid and amine substrates (without significant preferences), and co-cultures of cells proliferated more successfully than individual cultures.
