Separation of Human Epidermal Cells by Using Percoll / 대한피부과학회지

ABSTRACT

The epidermis, which is composed mainly of keratinocyt;es, undergoes continual proliferation and differentiation, To study keratinocyte differentiation, it is necessary to separate the keratinocytes at their sucessive stages of maturation. We separate the keratinocytes by layers by using Percoll and obtain the relatively pure fractions of basal cells, spinous cells, and granular cells, 76. 8%, 67. 2%, 30%. respectively.
