Analyzing the role of the fusome in symmetry breaking during gametogenesis

#Fusome #Gametogenesis #image #processing #cell #division

Proper development and growth of all organisms requires biological decisions that are precisely defined spatially and temporally.  In many cases, these processes arise from the breaking of some symmetry, creating new structures essential for continued development.  Throughout oogenesis and spermatogenesis, many symmetry breaking events must occur to ensure proper formation and patterning of the developing organism.  A key feature in Drosophila cyst formation in both cases is the presence of the fusome, a membranous organelle that stretches throughout all cells in the cyst and enables intercellular transport.  However, while the presence of this organelle is well-appreciated in developing males and females, systematic quantification of its evolution and structure throughout sperm and egg development has lacked.  Here, we use simple mathematical models and image processing tools to analyze three key symmetry breaking events in Drosophila gametogenesis: fusome growth and evolution, oocyte selection, and male germline cyst formation.
