Abstrakt:	Spermatogenesis is one of the most dramatic cellular differentiation events observed in animals. In particular, spermiogenesis (the final stage of spermatogenesis) involves extensive shedding of cytoplasmic organelles, dramatic nuclear rearrangements, and assembly of long flagellar structures. In planarian flatworms, the spherical nucleus present in round spermatids elongates to produce the filamentous nucleus of mature sperm. Newly formed cortical microtubules participate in cytoskeletal rearrangements observed during spermiogenesis and remain present in sperm. In addition, a pair of flagella assemble at one end of each spermatid in a process that likely involves de novo formation of centrioles. This chapter includes a brief introduction to planarian spermatogenesis and current tools for the analysis of molecular players in this process. Step-by-step protocols for isolating and imaging spermatogenic cells are provided with enough detail to be carried out by newcomers to the field who would like to study this unique organism in the laboratory.
