• DMBA/TPA-induced melanomas involve the epidermo-dermal junction and show vertical invasive growth into the dermis; at 12 weeks of age, vertical tumor thickness is larger than that in Cdk4tm1.1Bbd/Cdk4+ Tg(Mt1-HGFSF)#Lmb/0 mice

|
|
• DMBA/TPA-treated mice show locoregional metastatic growth of melanoma cells in the draining lymph nodes as well as numerous melanoma micrometastases in lung tissue
• in lymph nodes of DMBA/TPA-treated mice, melanoma cells are mostly spindle-shaped cells with little/no melanin that eventually disrupt lymph node architecture and displace lymphoid cells; however, heavily pigmented epitheloid melanoma cells are also observed

|
|
• all DMBA/TPA-treated mice develop rapidly growing skin melanomas reaching >10 mm in diameter at 12 weeks of age
• few mitoses and a low % of Ki67 staining are noted in spindle-shaped melanoma cells near the invasion front, indicating proliferative activity of melanoma cells
|
|
