• hematopoietic stem and progenitor cells (HSPCs) of mice treated with tamoxifen do not exhibit a selective advantage over cells not expressing the modified cDNA
• the total number of HSPCs is normal in irradiated mice
• following irradiation, the proportion of GFP+ cells in the hematopoietic stem and progenitor cell compartment and myeloid and lymphoid lineages of tamoxifen-treated mice is increased compared to un-irradiated mice
• GFP+ cell accumulation occurs whether mice are treated with tamoxifen 2 or 7 days after irradiation
• however, no competitive advantage is observed when mice are treated with tamoxifen and 5-fluorouracil without DNA damage or over similarly treated Cdkn2atm2.1Rdp cells in irradiated chimera experiments

neoplasm
• mice develop a tumor within the skull between 3 and 6 months of age; tumors are found primarily in the brain parenchyma, but also in the choroid plexus and orbit
• tumors show characteristic nests of polygonal cells with an open chromatin pattern, surrounded by neatly arcading capillary and larger vascular channels, resembling alveolar soft part sarcoma
• tumors often arise in or near the leptomeninges, along sulci
• some tumors show aggressive invasive growth, with extensions of tumor cells into the cerebellum, cerebrum, and the vessels of the choroid plexus
• mice do not develop tumors in the skeletal muscle
• tumors form in the areas highest in lactate, the cranial vault, express high levels of lactate importers, have abundant mitochondria, metabolize lactate as a metabolic substrate, and respond to exogenous lactate administration with increased cell proliferation and angiogenesis

craniofacial
• mice often exhibit enlargement of the occipital bone from the inner soft tissue expansion

• administration of tamoxifen prior to 3 weeks of age results in stunted growth

mortality/aging
• administration of tamoxifen prior to 3 weeks of age results in death by 12 weeks of age without tumor formation

neoplasm
• when tamoxifen is administered after 3 weeks of age more tumors form than without tamoxifen
• tumors most often in extremities, rib cage, and facial tissue
• tumors rare in dermis, liver, and bone
• mice develop clear cell sarcoma mimicking tumors across a broad anatomic distribution at 3-6 months of age in the absence of tamoxifen, indicating leakiness of the cre transgene
• all mice have tumors by 12 weeks regardless of treatment

• in MEFs at later time points after OHT treatment and serum addition cells develop large aberrant nuclei with frequent micronuclei

• in MEFS after OHT treatment and serum addition more cells are in prophase and most of these show an early prophase phenotype
• in MEFS after OHT treatment and serum addition almost no cells in metaphase, anaphase, and telophase are detected
• in MEFS after OHT treatment and serum addition cells in prometaphase have a monopolar spindle with closely adjacent chromosomes, the presence of these monopolar spindles activates the spindle checkpoint
• in MEFS 28 h after OHT treatment and serum addition the percent of cells positive for PH3 is increased about 3 fold compared to controls
