Abstract
Genetically engineered mouse models of lung adenocarcinoma have proven invaluable for understanding mechanisms of tumorigenesis, therapy response, and drug resistance. However, mechanistic studies focused on studying these processes in tumor-bearing mouse lungs are confounded by the fact that, in most cases, relevant signaling pathways are analyzed in whole-lung preparations, which are composed of a heterogeneous mixture of cells. Given our increasing knowledge about the roles played by different subpopulations of cells in the development of lung adenocarcinoma, separating the major cellular compartments of the tumor microenvironment is recommended to allow for a precise analysis of relevant pathways in each isolated cell type. In this study, we optimized magnetic- and fluorescence-based isolation protocols to segregate lung epithelial (CD326/epithelial cell adhesion molecule-positive), endothelial (CD31-positive), and immune (CD45-positive) cells, with high purity, from the lungs of transgenic mice with mutant epidermal growth factor receptor-induced lung adenocarcinomas. This approach, which can potentially be extended to additional lung adenocarcinoma models, enables delineation of the molecular features of individual cell types that can be used to gain insight into their roles in lung adenocarcinoma initiation, progression, and response to therapy.

Abstract
The INHAND Project (International Harmonization of Nomenclature and Diagnostic Criteria for Lesions in Rats and Mice) is a joint initiative of the Societies of Toxicologic Pathology from Europe (ESTP), Great Britain (BSTP), Japan (JSTP) and North America (STP) to develop an internationally-accepted nomenclature for proliferative and non-proliferative lesions in laboratory animals. The purpose of this publication is to provide a standardized nomenclature for classifying microscopic lesions observed in the respiratory tract of laboratory rats and mice, with color photomicrographs illustrating examples of some lesions. The standardized nomenclature presented in this document is also available electronically on the internet (http://www.goreni.org/). Sources of material included histopathology databases from government, academia, and industrial laboratories throughout the world. Content includes spontaneous developmental and aging lesions as well as lesions induced by exposure to test materials. A widely accepted and utilized international harmonization of nomenclature for respiratory tract lesions in laboratory animals will decrease confusion among regulatory and scientific research organizations in different countries and provide a common language to increase and enrich international exchanges of information among toxicologists and pathologists.

Abstract
Injury models have suggested that the lung contains anatomically and functionally distinct epithelial stem cell populations. We have isolated such a regional pulmonary stem cell population, termed bronchioalveolar stem cells (BASCs). Identified at the bronchioalveolar duct junction, BASCs were resistant to bronchiolar and alveolar damage and proliferated during epithelial cell renewal in vivo. BASCs exhibited self-renewal and were multipotent in clonal assays, highlighting their stem cell properties. Furthermore, BASCs expanded in response to oncogenic K-ras in culture and in precursors of lung tumors in vivo. These data support the hypothesis that BASCs are a stem cell population that maintains the bronchiolar Clara cells and alveolar cells of the distal lung and that their transformed counterparts give rise to adenocarcinoma. Although bronchiolar cells and alveolar cells are proposed to be the precursor cells of adenocarcinoma, this work points to BASCs as the putative cells of origin for this subtype of lung cancer.

Abstract
In recent years several new mouse models for lung cancer have been described. These include models for both non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC). Tumorigenesis in these conditional mouse tumor models can be initiated in adult mice through Cre-recombinase-induced activation of oncogenic mutations in a subset of the cells. They present a marked improvement over mouse models that depend on carcinogen induction of tumors. These models permit us to study the consecutive steps involved in initiation and progression and allow us to address questions like the cell of origin, and the role of cancer stem cells in the maintenance of these tumors. They now need to be validated as suitable preclinical models for intervention studies in which questions with respect to therapy response and resistance can be addressed.

Abstract
Lung cancer is a devastating disease that presents a challenge to basic research to provide new steps toward therapeutic advances. The cell-type-specific responses to oncogenic mutations that initiate and regulate lung cancer remain poorly defined. A better understanding of the relevant signaling pathways and mechanisms that control therapeutic outcome could also provide new insight. Improved conditional mouse models are now available as tools to improve the understanding of the cellular and molecular origins of adenocarcinoma. These models have already proven their utility in proof-of-principle experiments with new technologies including genomics and imaging. Integrated thinking to apply technological advances while using the appropriate mouse model is likely to facilitate discoveries that will significantly improve lung cancer detection and intervention.

Abstract
Rapid advances in generating new mouse genetic models for lung neoplasia provide a continuous challenge for pathologists and investigators. Frequently, phenotypes of new models either have no precedents or are arbitrarily attributed according to incongruent human and mouse classifications. Thus, comparative characterization and validation of novel models can be difficult. To address these issues, a series of discussions was initiated by a panel of human, veterinary, and experimental pathologists during the Mouse Models of Human Cancers Consortium (NIH/National Cancer Institute) workshop on mouse models of lung cancer held in Boston on June 20-22, 2001. The panel performed a comparative evaluation of 78 cases of mouse and human lung proliferative lesions, and recommended development of a new practical classification scheme that would (a) allow easier comparison between human and mouse lung neoplasms, (b) accommodate newly emerging mouse neoplasms, and (c) address the interpretation of benign and preinvasive lesions of the mouse lung. Subsequent discussions with additional experts in pulmonary pathology resulted in the current proposal of a new classification. It is anticipated that this classification, as well as the complementary digital atlas of virtual histological slides, will help investigators and pathologists in their characterization of new mouse models, as well as stimulate further research aimed at a better understanding of proliferative lesions of the lung.

Abstract
Adenocarcinoma of the lung is the most common form of lung cancer, but the cell of origin and the stages of progression of this tumor type are not well understood. We have developed a new model of lung adenocarcinoma in mice harboring a conditionally activatable allele of oncogenic K-ras. Here we show that the use of a recombinant adenovirus expressing Cre recombinase (AdenoCre) to induce K-ras G12D expression in the lungs of mice allows control of the timing and multiplicity of tumor initiation. Through the ability to synchronize tumor initiation in these mice, we have been able to characterize the stages of tumor progression. Of particular significance, this system has led to the identification of a new cell type contributing to the development of pulmonary adenocarcinoma.

Abstract
Primary lung tumors in mice have morphologic, histogenic, and molecular features similar to human lung adenocarcinoma, and in particular, the bronchiolo-alveolar carcinoma subtype. Because of this, and because of the genetic homology between man and mouse and the ease of genetic manipulations in mice, this model system is receiving intense research attention. This review is intended to be informative to clinical investigators, and describes features of this model, how it is being used for translational research, and points out additional avenues of study that could have practical benefits, such as application for identifying novel therapeutic strategies.

Abstract
Mice injected with urethane develop tumors with distinct histological patterns, which are classified as solid, papillary, or a mixture of these two patterns within the same tumor. Most investigators agree that solid tumors arise from alveolar type II cells, but the cellular origin of papillary tumors is less certain, being attributed to either type II cells or nonciliated bronchiolar epithelial (Clara) cells. To characterize the state of differentiation of these tumors more precisely and to provide additional information on gene expression, we used immunocytochemistry and/or in situ hybridization to determine the cellular localization of surfactant-associated proteins A (SP-A), SP-B, SP-C, and SP-D; Clara cell-associated protein CC-10; and thyroid transcription factor-1. In normal mouse lung, the messenger RNAs (mRNAs) for SP-A, SP-B, and SP-D were expressed in both type II cells and Clara cells. SP-C mRNA, however, was expressed only in type II cells, and CC-10 expression of mRNA was restricted to Clara cells. All tumors examined, both solid and papillary, expressed SP-A, SP-B, SP-C, SP-D, and thyroid transcription factor-1, but not CC-10. However, SP-C expression was slightly diminished in larger (older) papillary tumors. These results demonstrate that urethane-induced murine lung tumors express the type II cell phenotype.

Abstract
The pulmonary tumorigenicity of dimethylarsinic acid (DMAA), a main metabolite of inorganic arsenics, was examined in A/J mice fed with drinking water containing DMAA for 25 and 50 weeks. Mice fed with 400 ppm DMAA for 50 weeks produced more pulmonary tumors than untreated mice (mean number per animal 1.36 versus 0.50; P < 0.05). Histological examination revealed that the number of mice which bore adenocarcinomas or papillary adenomas correlated with the concentration of DMAA given (untreated versus 400 ppm; P = 0.002), suggesting that DMAA could promote tumorigenic processes. These results are consistent with the epidemiological studies on the pulmonary carcinogenesis of arsenics and suggest that DMAA alone can act as a carcinogen in mice.

Abstract
Because of the cellular complexity and spatial organization of the lung, investigation of the pathogenesis of human pulmonary diseases relies to a considerable extent upon the use of animal models. In this review, the author examines new models and new applications of existing models of pneumonia, asthma, emphysema, interstitial lung disease and neoplasms in laboratory mice and rats. Studies of such models may assist in the development of appropriate strategies for early diagnosis and intervention.

Abstract
Strain A mice develop a high incidence of spontaneous lung tumors during their lifetime. These tumors may be found in some animals as early as 3 to 4 weeks of age, increasing to nearly 100% by 24 months of age. The strain A mouse is also highly susceptible to the induction of lung tumors by several classes of chemical carcinogens and has been used extensively as a mouse lung tumor bioassay for assessing the carcinogenic activity of a variety of chemicals. In addition to its use in carcinogen detection, the strain A mouse lung tumor model has been employed extensively for the identification of inhibitors of chemical carcinogenesis. A number of chemopreventive agents including beta-naphthoflavone, butylated hydroxyanisole, ellagic acid, phenethyl isothiocyanate, phenylpropyl isothiocyanate, phenylbutyl isothiocyanate, phenylhexyl isothiocyanate, indole-3-carbinol, etc., have been shown to inhibit chemically induced lung tumors in strain A mice. In most instances, inhibition of lung tumorigenesis has been correlated with effects of the chemopreventive agent on the metabolic activation and/or detoxification of carcinogens. To date, no chemopreventive agent has been shown to inhibit lung tumorigenesis in strain A mice when administered after the carcinogen, i.e., during the promotion/progression stages of tumor development. Efforts should be made to develop a standardized protocol in strain A mice for evaluating chemopreventive agents as inhibitors of both the initiation and progression stages of lung tumor development.

Abstract
The histogenesis of mouse lung adenomas is currently being investigated in several laboratories. Based upon studies of a limited number of carcinogens in different mouse strains, some investigators suggest that all lung adenomas in mice are derived from alveolar type II cells, whereas others suggest a Clara cell origin for a majority of the tumors. This report differs from previous investigations in that 12 different carcinogens were evaluated for the types of lung tumor growth patterns they induced in a single mouse strain (strain A mice). The carcinogens aflatoxin B1 (AFB1), benzo(a)pyrene (BP), 1,2-dimethylhydrazine (DMH), 3-methylcholanthrene (MCA), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), and N-nitrosomethylurea (MNU) induced tumors with a predominantly solid/alveolar growth pattern, whereas N-nitrosodiethylamine (NDEA) induced predominantly papillary tumors. Most of the other carcinogens induced a higher proportion of lung tumors with the solid/alveolar growth pattern than with the papillary growth pattern; however, ratios between the 2 growth patterns varied. If, as suggested by others, solid tumors are derived from alveolar type II cells and papillary tumors from Clara cells, then carcinogens may differ with respect to their ability to transform one cell type or the other.
