neoplasm
• at 8-15 weeks after DMBA treatment, mice exhibit significantly increased melanoma multiplicity relative to control mice, with primary melanomas invading the dermis and showing tumor-associated angiogenesis
• less than 15 weeks after DMBA treatment, mice show increased incidence of distal melanoma metastases in the lungs relative to control mice (57.1% versus 16.7%)
• in DMBA-treated mice, primary melanomas show an increased proliferative index, with a significantly higher number of PCNAhigh melanoma cells relative to control mice, consistent with increased melanoma multiplicity

homeostasis/metabolism
• at 8-15 weeks after DMBA treatment, mice exhibit significantly increased melanoma multiplicity relative to control mice, with primary melanomas invading the dermis and showing tumor-associated angiogenesis

neoplasm
• in a 2-step (DMBA/TPA) skin carcinogenesis protocol, all (18 of 18) mice develop slowly growing skin melanomas with an average of 12 cutaneous melanomas
• DMBA/TPA-induced melanomas involve the epidermo-dermal junction and show vertical invasive growth into the dermis; however, no proliferative activity of melanoma cells is detected by Ki67 staining
• 10 of 18 DMBA/TPA-treated mice also develop large subcutaneous cystic tumors filled with serous liquid and have to be sacrificed by 30 weeks of age
• all DMBA/TPA-treated mice develop on average 3 papillomas in the skin; these appear early after carcinogen treatment
• at 30 weeks of age, untreated mice exhibit melanocytic nevi in skin
• however, untreated mice are all alive and healthy at 1 year of age
• DMBA/TPA-treated mice show locoregional metastatic growth of melanoma cells in draining lymph nodes as well as numerous melanoma micrometastases in lung tissue
• in lymph nodes of DMBA/TPA-treated mice, melanoma cells are mainly 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
• in DMBA/TPA-treated mice, the average number of lung metastases is comparable to that in Cdk4tm1.1Bbd/Cdk4+ Tg(Mt1-HGFSF)#Lmb/0 mice

neoplasm
• in a 2-step (DMBA/TPA) skin carcinogenesis protocol, all (16 of 16) mice show melanocytic nevi within the first weeks of life while still under TPA treatment
• all DMBA/TPA-treated mice develop widespread, rapidly growing skin melanomas and have to be sacrificed by 12 weeks of age due to melanomas >10 mm in diameter and systemic signs of illness; an average of ~48 cutaneous melanomas is observed
• 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
• heavily pigmented epitheloid melanoma cells are arranged in bands and nests between lightly pigmented spindle-shaped melanoma cells
• only 3 of 16 DMBA/TPA-treated mice develop a single papilloma in skin
• at 30 weeks of age, untreated mice exhibit a similar number of melanocytic nevi in skin as untreated Tg(Mt1-HGFSF)#Lmb/0 mice
• untreated mice develop single, rapidly growing, spontaneous skin melanomas starting at ~30-40 weeks of age; ~20% of these mice have to be sacrificed by 1 year of age, with primary melanomas >10 mm in diameter
• 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

• untreated mice with large spontaneous primary melanomas arising in skin also show locoregional metastases in adjacent draining lymph nodes as well as distal micrometastases in the lungs
• 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
