Substrates, inhibitors, or other compounds are added to the culture medium in final concentrations as referred to in the text and shown in the tables. The ear fragments are incubated for 1 hour to allow all mitoses originally present in the epidermis to pass beyond metaphase. At this point, the experimental period begins. Colchicine is tipped...

Colchicine is tipped into the main vessel of the Warburg flask and incubation is continued further for 4 hours. The effects of various substrates, compounds, or culture conditions on the development of epidermal mitosis are determined in histological sections by counting the number of metaphase figures arrested by colchicine during the 4-hour experimental period. Observations...
