A comprehensive analysis of chromosomal anomalies in metaphase II spermatocytes from infertile patients
Cell suspensions were fixed using methanol:acetic acid (3:1) and dropped onto slides. Samples were analyzed following a sequential methodology combining Leishman’s staining (PanReac AppliChem, Castellar del Vallès, Spain) and multiplex fluorescence in situ hybridization (M-FISH, Spectra VysionTM Assay Protocol, Vysis Inc., Downers Grove, IL, USA) to identify unequivocally all chromosomes.2 MII ...

The spindle apparatus is a vital structure and must be structurally intact for proper segregation of the oocyte's genetic material during metaphase II. Endometriosis, oxidative stress, and cryopreservation can all adversely affect the structural integrity of the spindle, potentially resulting in aneuploidy and spontaneous abortion of the embryo. Advances in spindle imagery have made it possible...
متن کاملChromosomal Structures in Crayfish Spermatocytes

Indeed, even the grosset morphology long familiar to cytologists in the light microscope is harldy recognizable, partly for want of suitable electron stains and partly, undoubtedly, because of fixation and preparative effe...
