Culturing keratinocytes to form coherent epithelial tissue sheets has improved the treatment of extensively burned patients. Keratinocyte culture is also used to investigate various cellular and molecular mechanisms involved in different skin pathologies. To preserve stem cells during epithelial cell culture, reliable methods and conditions are of the utmost importance. Properly cultured keratinocytes will exhibit a consistent cuboid morphology and can proliferate for many passages. This chapter details materials needed and methods for all aspects of efficient keratinocyte culture for clinical applications, namely tissue sampling and transportation, isolation, routine culture, subculture, and cryopreservation.
