Background: Preterm deliveries remain the leading cause of neonatal morbidity and mortality. Current therapies target only myometrial contractions and are largely ineffective. As labor involves multiple coordinated events across maternal and fetal tissues, identifying fundamental regulatory pathways of normal term labor is vital to understanding successful parturition and consequently labor pathologies. We aimed to identify transcriptomic signatures of human normal term labor of two tissues: in the fetal-facing choriodecidua and the maternal myometrium...

Loss of photoreceptor cells due to retinal degeneration is one of the main causes of blindness in the developed world. Although there is currently no effective treatment, cell replacement therapy using stem-cell-derived photoreceptor cells may be a feasible future treatment option. In order to ensure safety and efficacy of this approach, robust cell isolation and purification protocols must be developed. To this end, we previously developed a biomarker panel for the isolation of mouse photoreceptor precursors from the developing mouse retina and mouse embryonic stem cell cultures...

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by the presence of antiphospholipid antibodies, such as lupus anticoagulant, anticardiolipin antibodies and anti-β2-glycoprotein 1 antibodies. APS can present with a variety of clinical phenotypes, including thrombosis in the veins, arteries and microvasculature as well as obstetrical complications. The pathophysiological hallmark is thrombosis, but other factors such as complement activation might be important. Prevention of thrombotic manifestations associated with APS includes lifestyle changes and, in individuals at high risk, low-dose aspirin...

Spheroid culture has gained increasing popularity, arising as a promising tool for regenerative medicine applications. Importantly, spheroids may present advantages over single-cell suspensions in cell-based therapies (CT). Unfortunately, most growth media used for spheroid culture contain animal origin-components, such as fetal bovine serum (FBS). The presence of FBS compromises the safety of CT and presents economic and ethical constraints. SCC (supplement for cell culture) is a novel xeno-free (XF) industrial cell culture supplement, derived from well-controlled pooled human plasma and processed under good manufacturing practice rules...

Data from previous seasonal epidemics and pandemics have confirmed that pregnant women are at increased risk for severe influenza virus infection. Complications including fetal loss, higher rates of hospitalization and maternal death are most notable during the late gestational period. Antiviral therapy and influenza vaccination are recommended in pregnant women as both are effective and safe. This review discusses the epidemiology, pathophysiology, treatment and prevention of influenza virus infection in pregnancy, with a focus on recent developments...

Nicotine replacement therapy (NRT) is recommended in current Australian clinical guidelines for pregnant women who are unable to quit smoking unassisted. Clinicians report low levels of prescribing NRT during pregnancy, due to safety concerns and low levels of confidence in their ability to prescribe NRT. Animal models show that nicotine is harmful to the fetus, especially for brain and lung development, but human studies have not found any harmful effects on fetal and pregnancy outcomes. Studies of efficacy and effectiveness in the real world suggest that NRT use during pregnancy increases smoking cessation rates...

The imbalance of Th1/Th2 cytokines is well known in recurrent spontaneous abortion (RSA) mouse model. Mesenchymal stem cells (MSCs) possess potent immunoregulatory properties that could modulate the Th1 cytokine responses in benefit of Th2 types. In this study, we aimed to analyze the local and systemic balance of Th1/Th2 cytokines following MSCs therapy. Syngeneic adipose derived MSCs were administered to abortion prone mice during the implantation window. The abortion rate was determined and IL-4, IL-6, IL-12, IL-2, IFN-γ and GM-CSF gene expression was evaluated by Real-Time-PCR in decidual and placental tissues of pregnant mice at day 13...

Hypoplastic left heart syndrome (HLHS) encapsulates a spectrum of complex congenital cardiovascular malformations involving varying degrees of underdevelopment of the left-sided heart structures. However, despite improved survival rates since the introduction of staged surgical reconstruction, treatment options for HLHS remain palliative rather than curative. A major limiting factor in the development of definitive curative therapy for HLHS is an incomplete understanding of its pathogenesis. Currently, the aetiology HLHS is best conceptualised by the 'flow theory' of cardiogenesis, which states that normal cardiac development is reliant on the interrelationship of normal flow patterns of blood through the developing heart, and appropriate growth of the cardiac valves and myocardium...

Since the discovery of scarless fetal skin wound healing, research in the field has expanded significantly with the hopes of advancing the finding to adult human patients. There are several differences between fetal and adult skin that have been exploited to facilitate scarless healing in adults including growth factors, cytokines, and extracellular matrix substitutes. However, no one therapy, pathway, or cell subtype is sufficient to support scarless wound healing in adult skin. More recently, products that contain or mimic fetal and adult uninjured dermis were introduced to the wound healing market with promising clinical outcomes...

Treating neurodegenerative diseases with cell transplantation has been within reach since the first pioneering clinical trials in which dopamine neuron progenitors from the fetal brain were transplanted to individuals with Parkinson's disease. However, the use of fetal tissue is problematic in terms of low availability and high variability, and it is also associated with ethical concerns that vary between countries. For decades, the field has therefore investigated new scalable source of therapeutic cells from stem cells or via reprogramming...

Organ-on-a-chip technology can simulate the physiological and pathological microenvironment of tissues and organs in vitro, thus offering the potential of dispensing with animal models to predict the toxicity and efficacy of therapies. In this study, taking the alveolar microenvironment as a model, we developed a lung-on-a-chip with a poly(lactic-co-glycolic acid) (PLGA) electrospinning nanofiber membrane as the chip substrate and cell scaffold. The PLGA nanofiber membrane, with a controlled thickness of ∼3 μm, is porous and permeable to molecules, has good biocompatibility, and offers a means to simulate the alveolar respiratory membrane...

Isoprenoids play widely differing roles in various physiological processes in animals and plants. Geranylgeraniol (GGOH) is an isoprenoid found in plants, and is an important metabolic derivative in the isoprenoid/cholesterol synthesis pathway. Earlier studies focused on GGOH's ability to improve the side effects of bisphosphonate therapy by regulating the mevalonate pathway. More recently, the mevalonate pathway-independent effects of GGOH have been described, including anti-inflammatory, anti-tumorigenic, and neuroprotective activities...

Pregnancies affected by preeclampsia (PE) or fetal growth restriction (FGR) display increases in thrombin generation and reductions in angiogenesis and cell growth. There is significant interest in the potential for low molecular weight heparins (LMWHs) to reduce the recurrence of PE and FGR. However, LMWH is associated with an increased risk of bleeding. Therefore, it is of vital importance to determine the exact molecular function of heparins in pregnancy if they are used as therapy for pregnant women. We aimed to determine this using our model for PE/FGR in microvascular endothelial cells...

Genes encoding the human β-like hemoglobin proteins undergo a developmental switch from fetal γ-globin to adult β-globin expression around the time of birth. β-hemoglobinopathies, such as sickle-cell disease and β-thalassemia, result from mutations affecting the adult β-globin gene. The only treatment options currently available carry significant adverse effects. Analyses of heritable variations in fetal hemoglobin (HbF) levels have provided evidence that reactivation of the silenced fetal γ-globin genes in adult erythroid cells is a promising therapy...
