Mouse skin carcinomas arise from a small subpopulation of benign papillomas with an increased risk of malignant conversion. These papillomas arise with limited stimulation by tumor promoters, appear rapidly, and do not regress, suggesting that they differ in growth properties from the majority of benign tumors. The transforming growth factor beta (TGF-beta) proteins are expressed in the epidermis and are growth inhibitors for mouse keratinocytes in vitro; altered TGF-beta expression ...

Transgenic mice that overexpress PKCalpha in the epidermis (K5-PKCalpha mice) exhibit acute CXCR2-mediated intraepidermal neutrophilic inflammation and a strong epidermal hyperplasia in response to application of 12-O-tetradecanoylphorbol-13-acetate (TPA). We now show that hyperplasia is independent of infiltrating neutrophils. Furthermore, when K5-PKCalpha mice were initiated with 7,12-dimethylbenz(a)anthracene (DMBA) and promoted with a low dose of TPA, 58% of K5-PKCalpha mice ...

The role of intracellular Ca2+ in the regulation of Ca(2+)-induced terminal differentiation of mouse keratinocytes was investigated using the intracellular Ca2+ chelator 1,2-bis(o-aminophenoxy)-ethane-N,N,N',N'-tetraacetic acid (BAPTA). A cell permeable acetoxymethyl (AM) ester derivative BAPTA (BAPTA/AM) was loaded into primary mouse keratinocytes in 0.05 mM Ca2+ medium, and then the cells were induced to differentiate by medium containing 0.12 or 0.5 mM Ca(2+) Intracellular BAPTA ...

Disaggregated epidermal cells, sheets of epidermis, and explants of partial and full-thickness skin have been grown in cell, organ, and explant cultures. Each type of epidermal sample has also been "cultured" as a graft on a living animal host. The extent of tissue-specific phenotypic expression by the epidermal cell varies with the type of culture and the culture conditions: medium, biologic and pharmacologic additives, substrate, cell density, pH, and temperature. Specific culture ...

TUMOUR-PROMOTING agents have been defined by their ability to promote tumour formation on carcinogen-initiated mouse skin. The most potent of these agents are the diesters of phorbol which are the active components of croton oil, the classic promoting substance. Phorbol esters can be chemically modified in a number of positions to form molecules with a wide range of promoter potency1. Such modifications have been useful in determining structure-function relationships2. A good correlation ...

Calcium modulation of keratinocyte growth in culture was studied by both transmission (TEM) and scanning electron microscopy (SEM). Under standard culture conditions (1.2-1.8 mM calcium), cells were connected by desmosomes and stratified to 4-6 cell layers. Many aspects of in vitro epidermal maturation were analogous to the in vivo process, with formation of keratohyalin granules, loss of nuclei, formation of cornified envelopes and shedding of cornified cells containing keratin ...

Modification of the ionic calcium concentration in the culture medium markedly alters the pattern of proliferation and differentiation in cultured mouse epidermal cells. When medium calcium is lowered to 0.05--0.1 mM, keratinocytes proliferate rapidly with a high growth fraction and do not stratify, but continue to synthesize keratin. The cells grow as a monolayer for several months and can be subcultured and cloned in low Ca++ medium. Ultrastructural examination of cells cultured under ...
