Mitosis

Mitosis is a dynamic and stochastic process that has evolved to accurately segregate the geneticmaterialintotwodaughtercells,therebypreventinggenomicinstabilityandthe developmentofdisease. Mitosisisaphenomenallycomplicatedprocessthatinvolvesh- dreds,ifnotthousands,ofproteincomponentsandregulatorystepsthatoperateinboth spaceandtimetodrivecelldivision. Modernmethodsmakeitpossibletoaskformechan- ticprinciplesunderlyingthisbewilderingcomplexity. Themainpurposeofthisvolumeis toprovideanup-to-datecollectionofmethodsandapproachesthatareusedtoinvestigate themechanismofmitosisatthemolecularlevel. Whilemanyofthesemethodsarefocused onmammaliancells,wehave,whereappropriate,includedchaptersusingmodelorg- isms. We hope to capture both current approaches and the future direction of method development,withcontributionsfrombothestablishedresearchersandemergingyoung scientists. Thisbookisdesignedwithtwogeneralgroupsofreadersinmind:First,graduates- dentsandpostdoctoralresearcherswhoarebeginningworkforthe?rsttimeinamitosis laboratory. Second,researcherswhoarealreadyworkinginthemitosis?eldwhorequire a resource for both established and newly developed methodologies.To achieve this, the organization of this book developed into three general areas: First, we cover me- ods that can be used to inactivate your gene of interest, or deplete proteins of interest (chapters1-3). Second,welearnaboutspeci?cbiochemicalandmicroscope-basedme- ods (chapters 4-9). Third, we discover approaches to monitor and measure key mitotic processes(chapters9-20).

I would like to thank all of the authors for their enthusiasm and effort in putting togetherthissetofmethods,aswellasallthemembersofmylaboratoryforproofreading and correcting the chapters and especially Sarah McClelland who read all the chapters atleasttwiceatvariousstages.
