We report the generation of human induced pluripotent stem cells (hiPSCs) from dermal fibroblasts of a female patient carrier of the two compound heterozygous mutations c.568 C>T p.R190W (maternal allele), and c.1781 G>A p.R594Q (paternal allele) on the KCNQ1 gene, causing Jervell and Lange-Nielsen Syndrome (JLNS). To obtain hiPSCs, we used the classical approach of the four retroviruses each encoding for a reprogramming factor OCT4, SOX2, KLF4, cMYC. The obtained hiPSC clones display pluripotent stem cell characteristics, and differentiate into spontaneously beating cardiomyocytes (hiPSC-CMs)...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and other aryl hydrocarbon receptor (AhR) agonists have been shown to regulate bone development and remodeling in a species-, ligand-, and age-specific manner, however the underlying mechanisms remain poorly understood. In this study, we characterized the effect of 0.01-30 μg/kg TCDD on the femoral morphology of male and female juvenile mice orally gavaged every 4 days for 28 days and used RNA-Seq to investigate gene expression changes associated with the resultant phenotype...

INTRODUCTION: Mesenchymal stem cells are already used in numerous areas of medicine. In the field of plastic surgery, the main focus of recent research has been to utilise adipose-derived stromal cells (ASCs), mainly harvested via liposuction. The ability to release regenerative cytokines is supposed to be the key mechanism for the therapeutic efficacy of ASCs. There are currently a variety of methods and devices in clinical use for harvesting lipoaspirate and consequently ASCs. For most of these devices, the effect on the regenerative cytokine profile of ASCs is unknown...

OBJECTIVE: In the current study, we aimed to accurately evaluate donor/recipient or male/female chimerism in samples from patients who underwent hematopoietic stem cell transplantation (HSCT). METHODS: We designed the droplet digital polymerase chain reaction (ddPCR) for SRY and RPP30 to detect the male/female chimerism. We also developed mutation-specific ddPCR for four primary immunodeficiency diseases. RESULTS: The accuracy of the male/female chimerism analysis using ddPCR was confirmed by comparing the results with those of conventional methods (fluorescence in situ hybridization and short tandem repeat-PCR) and evaluating dilution assays...

Proper specification of germline stem cells (GSCs) in Drosophila ovaries depends on niche derived non-autonomous signaling and cell autonomous components of transcriptional machinery. Stonewall (Stwl), a MADF-BESS family protein, is one of the cell intrinsic transcriptional regulators involved in the establishment and/or maintenance of GSC fate in Drosophila ovaries. Here we report identification and functional characterization of another member of the same protein family, CG3838/Brickwall (Brwl) with analogous functions...

BACKGROUND: Beta thalassemia major (BTM) and its treatment by hematopoietic stem cell transplantation (HSCT) may have deleterious effects on the endocrine systems. We assessed endocrine complications of HSCT in pediatric patients for 3 months. METHODS: In 20 (6 female) pediatric major thalassemic patients (mean age of 10.8 ± 3.9 years old), prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), T4, T3, thyroid-stimulating hormone (TSH), IGF-1, testosterone (in males) or estradiol (in females) were measured as a batch at the Endocrinology and Metabolism Research Center (EMRC) of Tehran University of Medical Sciences (TUMS) laboratories before HSCT and 1 and 3 months afterwards...

Best disease (BD), also termed Best vitelliform macular dystrophy (BVMD), is a juvenile-onset form of macular degeneration and central visual loss. In this report, we generated an induced pluripotent stem cell (iPSC) line, TVGH-iPSC-012-04, from the peripheral blood mononuclear cells of a female patient with BD by using the Sendai virus delivery system. The resulting iPSCs retained the disease-causing DNA mutation, expressed pluripotent markers and could differentiate into three germ layers. We believe that BD patient-specific iPSCs provide a powerful in vitro model for evaluating the pathological phenotypes of the disease...

LIF-mediated STAT3 signaling is critically involved in stem cells and development. However, its function in mouse female germline cells (FGSCs) remains elusive. In this study, we demonstrated that LIF-induced STAT3 activation contributes to the proliferation and undifferentiation maintenance of mouse FGSCs. Characterization of the STAT3-mediated transcriptional network by intersecting ChIP-seq and RNA-seq datasets revealed 405 direct target genes of STAT3, which are primarily involved in proliferation and germline development...

Common protocols for chondrogenic differentiation of adipose-derived mesenchymal stem cells (ADSCs) are generally expensive and time-consuming and so far, have not successfully recreated pure chondrocytes. We hypothesize that a low level of H2 O2 may induce differentiation of ADSCs into chondrocytes in a shorter incubation time and relatively lower cost. Therefore, this study aimed to comparatively investigate the effectiveness of H2 O2 -containing or free medium in the induction of ADSCs to chondrocytes. ADSCs were isolated from the lipoaspirate of four healthy females and evaluated by immunophenotyping for their CD90, CD73, CD44, CD34, and CD45 cell surface markers...

PURPOSE OF REVIEW: The current review provides an update on recent advances in stem cell biology relevant to female reproduction. RECENT FINDINGS: Stem cells are undifferentiated cells that often serve as a reservoir of cells to regenerate tissue in settings or injury or cell loss. The endometrium has progenitor stem cells that can replace all of the endometrium during each menstrual cycle. In addition, multipotent endometrial cells replace these progenitor cells when depleted...

Uncontrolled host immunological reactions directed against tissue-trapped eggs precipitate a potentially lethal, pathological cascade responsible for schistosomiasis. Blocking schistosome egg production, therefore, presents a strategy for simultaneously reducing immunopathology as well as limiting disease transmission in endemic or emerging areas. We recently demonstrated that the ribonucleoside analogue 5-azacytidine (5-AzaC) inhibited Schistosoma mansoni oviposition, egg maturation and ovarian development...

Up to the 18th century, the prevailing view of reproduction, or 'generation' as it was referred to, was that organisms develop from miniatures of themselves, termed preformation. The alternative theory, epigenesis, proposed that the structure of an animal emerges gradually from a relatively formless egg. The teachings of the Ancient Greeks who argued either that both sexes each contributed 'semen' to form the embryo, or held a more male-centred view that the female merely provided fertile ground for the male seed to grow, dominated thinking until the 17th century, when the combined work of numerous scholars led to the theory that all female organisms, including humans, produced eggs...

Evidence from different sources sustains a pro-oncogenic role of hormones, estrogens and progestogens, on the breast. The issue is of interest for young women, who are exposed to the hormonal changes imposed by the ovarian cycle and, often, take hormones with contraceptive purposes. Experimental and clinical studies show that both estrogens and progesterone are involved in mammary development during puberty and lactation, the changes being observed across mammalian species, including humans. Estrogen receptors, and more particularly the alpha isoform, participate in molecular processes of stem cells differentiation and epithelial proliferation through paracrine actions implicating growth factors...

REVIEW
Elena Abati, Stefania Corti
Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by muscle weakness and atrophy resulting from progressive degeneration and loss of the anterior horn cells in the spinal cord and brain stem nuclei. The onset of weakness ranges from prenatal age to young adulthood. Thus, many female patients reach fertile age and may consider getting pregnant. However, only little information is available about outcomes and complications of pregnancy in women with SMA. In this review, we compared different studies on the subject, then we analyzed outcomes in the different stages of the pregnancy (preconceptional period, embryonal period, fetal period, delivery and post partum), with a special focus on maternal and fetal complications, prematurity, mode of delivery, anesthesiological risk, respiratory function and influence of pregnancy on the disease course...

INTRODUCTION: Bone marrow cells (BMC) from obese adult mice display an increased apoptosis rate over proliferation. Hematopoietic stem cells (HSC) form all blood cells and are important BMC used in cell therapy. Because it is known that prenatal development can be affected by adverse metabolic epigenetic programming from the maternal organism, this work aimed to investigate the effects of maternal overweight on placenta and fetal liver hematopoietic niches. METHODS: Overweight was induced in female mice by overfeeding during lactation...

BACKGROUND: Triptorelin, a gonadotropin releasing hormone analogue, can be administered to postpubertal female individuals with cancer who receive chemotherapy to obtain menstrual suppression and decrease the risk of hemorrhage caused by thrombocytopenia. Our goal was to assess whether triptorelin also has a protective role against the gonadotoxicity of chemotherapy. PATIENTS AND METHODS: This retrospective observational study includes all postmenarchal female patients who presented to our Unit from 2000 to 2015 and received chemotherapy for cancer...
