Background: Primary culture takes place following the cell isolation from tissues. Isolation and culture of melanocytes based on their roll in the protection of body against hazardous sun rays, production of skin, cornea and hair color is really important. This study was done to set isolation, culture and proliferation of melanocytes from children foreskin and adult eyelashes, and also comparison of two types of melanocyte culture medium.
Methods: Human foreskin and eyelash samples were used for melanocyte isolation and culture. After isolation of epidermis from dermis, epidermis cell suspensions were prepared by enzymatic digestion. The isolated cells were cultured in two melanocyte selective culture media. Immunocytochemistary and reverse transcription-polymerase chain reaction (RT-PCR) assays were used for confirmation of isolated and cultured melanocytes.
Results: Our results indicated that isolated melanocyte cultured in the selective medium without phorbol esters is better than the melanocytes cultured in selective medium cont-aining phorbol esters not only morphologically but also physiologically and from the aspect of cell adhesion. In addition, the results showed that isolated melanocyte from adult eyelashes are more dendritic than melanocytes isolated from children foreskin. Conversely, our results indicated that the number of cell passages in melanocyte isolat-ed from foreskin is more than melanocytes isolated from adult eyelashes.
Conclusion: Melanocytes cultured in selective medium containing convenient growth factors in absence of phorbol esters show more native physiological and adhesive properties. In addition, melanocyte isolated from younger tissues such as foreskin have better proliferative and sub-culturing properties so we suggest isolation and culture of younger tissues.
