Skin papillomas were induced in transgenic mice overexpressing CDK4 in the epidermis (K5CDK4) by the two-stage carcinogenesis protocol as we previously described (27 (link),28 (link)). Briefly, groups of 20 mice each (K5CDK4 and wild type siblings) were initiated at day 1 after birth by topical application of 50 mg of DMBA in 50 ml of acetone on the mouse back. At day 14, mice received 2.5 mg of TPA in 200 ml of acetone twice a week for 20 weeks. Skin papillomas were collected at the end of the experiment at 30 weeks. Immunohistochemical analysis of skin tumors was performed on paraffin-embedded sections from mouse skin papillomas as described below.
B6 cg tg krt1 15 egfp 2cot j
B6.Cg-Tg [Krt1-15-EGFP] 2Cot/J is a transgenic mouse strain that expresses enhanced green fluorescent protein (EGFP) under the control of the keratin 1-15 (Krt1-15) promoter. This model is useful for visualizing and studying keratinocytes and other epithelial cell types.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
