Female germ cells ofDrosophila require zygoticovo andotu product for survival in larvae and pupae respectively

Mutations in the genes ovo or otu can cause abnormal proliferation of XX germ cells, which leads to so-called ovarian tumors, or they can lead to the elimination of XX germ cells, such that adult females possess empty ovaries. Males carrying ovo or otu mutations are unaffected. To find out when this sexual dimorphism affects germ cells, we analyzed the requirement of embryos and larvae for zygo...

Assessment of In Vitro-Derived Germ Cells Contribution in Oogenesis in Female Mice Ovaries

Introduction: Contrary to a common belief, most mammalian females lose the ability of Germ Cell (GC) renewal and oogenesis during fetal life. Although, it has been claimed that germ line stem cells preserve oogenesis in postnatal mouse ovaries, that postnatal oogenesis keeps producing functional and sufficient GCs in the case of infertility (caused by different reasons) is doubtful. On the othe...

isolation and enrichment of mouse female germ line stem cells

objective: the existence of female germ-line stem cells (fgscs) has been the subject of a wide range of recent studies. successful isolation and culture of fgscs could facilitate studies on regenerative medicine and infertility treatments in the near future. our aim in the present study was evaluation of the most commonly used techniques in enrichment of fgscs and in establishment of the best p...

Visualization of Proprioceptors in Drosophila Larvae and Pupae

Proprioception is the ability to sense the motion, or position, of body parts by responding to stimuli arising within the body. In fruitflies and other insects proprioception is provided by specialized sensory organs termed chordotonal organs (ChOs). Like many other organs in Drosophila, ChOs develop twice during the life cycle of the fly. First, the larval ChOs develop during embryogenesis. Th...

Adult hematopoietic stem cells require NKAP for maintenance and survival.

Steady-state hematopoiesis is sustained through differentiation balanced with proliferation and self-renewal of hematopoietic stem cells (HSCs). Disruption of this balance can lead to hematopoietic failure, as hematopoietic differentiation without self-renewal leads to loss of the HSC pool. We find that conditional knockout mice that delete the transcriptional repressor NKAP in HSCs and all hem...
