Thus, bulge stem cells are multipotent and can give rise to epidermis, hair follicle and sebaceous gland lineages.
Such preparations are difficult to study pharmacologically because the tegument or epidermis restricts access of drugs to the muscles.
This relationship in stomatal density between lower and upper epidermis also held true for shade plants.
Accelerated melanin transfer to keratinocytes then results in a large increase in melanin granules in the epidermis (fig005hah).
Accelerated melanin transfer to keratinocytes then results in a large increase in melanin granules in the epidermis.
Structurally, the skin consists of epidermis, dermis and basement membrane zone.
The basement membrane is a zone of 0.1 mm thickness that connects the epidermis to the dermis.
As seedling growth proceeds, lipoxygenases become confined to cells surrounding the vascular bundle, to the epidermis and to the hypodermis.
