    Laboratory of Endocrinology and Tissue Culture, Institute of Zoology, Jagiellonian University, Krakow, Poland
    Folia Biol (Krakow) 51:181-8. 2003
    ..It should be stressed, however, that the effect of hormone stimulation or aromatase inhibitor action appeared to be dependent on the length of light cycles that bank voles were exposed prior to the isolation of Leydig cells...

    Waclaw Tworzydlo
    Institute of Zoology, Jagiellonian University, Krakow, Poland
    Genesis 43:49-58. 2005
    ..These findings indicate that in higher dipterans the processes leading to the formation of a functional egg are variable and often markedly different from those in the model organism, D. melanogaster...

    Department of Systematic Zoology, Institute of Zoology, Jagiellonian University, 30 060 Krakow, Poland
    Arthropod Struct Dev 37:310-20. 2008
    ..In other words, the rigid extensions keep the nucleus in the cell centre while the cytoplasm flows, in between these extensions, towards the intercellular bridge connecting the nurse cell with the oocyte...
  4. doi request reprint The Balbiani body in the female germline cells of an earwig, Opisthocosmia silvestris
    Waclaw Tworzydlo
    Department of Systematic Zoology, Institute of Zoology, Jagiellonian University, Ingardena 6, 30 060 Krakow, Poland
    Zoolog Sci 26:754-7. 2009
    ..We also show that in the cyst cells, the Bbs are invariably located next to the fusome, a specialized cytoplasm occupying the bridge connecting sibling cells...

    Waclaw Tworzydlo
    Department of Systematic Zoology, Institute of Zoology, Jagiellonian University, Krakow, Poland

    Department of Systematic Zoology, Institute of Zoology, Jagiellonian University, Krakow, Poland
    Arthropod Struct Dev 39:360-8. 2010

    Waclaw Tworzydlo
    Department of Developmental Biology and Morphology of Invertebrates, Institute of Zoology, Jagiellonian University, Krakow, Poland
    Cell Tissue Res 366:191-201. 2016

    Zoology (Jena) 117:200-6. 2014
    ..We suggest, in the light of these data, that the localization of the Bb together with the polar attachment of the bouquet chromosomes play a crucial role in the early asymmetrization of Thermobia oocytes. ..
  11. pmc Embryos of the viviparous dermapteran, Arixenia esau develop sequentially in two compartments: terminal ovarian follicles and the uterus
    Waclaw Tworzydlo
    Department of Developmental Biology and Morphology of Invertebrates, Institute of Zoology, Jagiellonian University, Krakow, Poland
    PLoS ONE 8:e64087. 2013
    ..Our results indicate that viviparity in arixeniids is more complex than previously considered. We propose the new term "pseudoplacento-uterotrophic viviparity" for this unique two-phase reproductive strategy...
  12. doi request reprint A very simple mode of follicular cell diversification in Euborellia fulviceps (Dermaptera, Anisolabididae) involves actively migrating cells
    Waclaw Tworzydlo

    Zoolog Sci 28:802-8. 2011
    ..This suggests that, in E. fulviceps, cells from at least one FCs subpopulation show the ability to change position within an ovarian follicle by means of active migration...
