Embryo-Forschung: Ethik jenseits von Checklisten Vorschlag für integrierte Ethik auf Grundlage eines aktiven Dialogs, um ethisch verantwortungsvolle Forschung mit embryonalen Modellen auf Stammzellenbasis zu ermöglichen.

#Forschung mit #Embryo Modellen auf Basis menschlicher #Stammzellen (hSCBEMs) ist aus rechtlicher und ethischer Sicht heikles Terrain. Experten unter Leitung von @jesseveenvliet.bsky.social vom @mpi-cbg.de, zusammen mit @uio.no, schlagen ein neues Rahmenwerk als Orientierungshilfe vor. #Medizinethik

Embryo fossil found in South Africa is world's oldest proof that mammal ancestors laid eggs Between 280 and 200 million years ago, a group of animals evolved which would eventually give rise to mammals, including humans: the therapsids. They were first described more than 150 years ago, based on fossils from South Africa. Since then, many more fossils have been discovered.

Ultra-processed food: A Hidden Threat to Fertility and Embryo Growth? In today's episode we're diving into groundbreaking research on how ultra-processed food (UPF) impacts couples trying to conceive. Drawing from a major prospective cohort study, we explore the surprising discovery that a man's diet may be just as critical for fertility as a woman's. We discuss findings linking higher paternal UPF intake to reduced fertility and maternal consumption to slower embryonic growth and smaller yolk sac volume early in pregnancy. Join us as we unpack these sex-specific findings and what they mean for the future of preconception care.

Schematics showing the mechanism of how ERK activity coordinates ME differentiation and cell cycle. When the pluripotent stem cells (PSCs) differentiate towards mesendoderm (ME), ERK activity increases. Multiple morphogens controlling ME differentiation contribute to the increase of ERK activity, which also quantitatively modulate ERK activity. Increased ERK activity promotes efficient TBXT expression without dramatic remodeling of cell cycle during ME differentiation. This is because the ranges of ERK activity that promote cell cycle progression and TBXT protein production are distinct. The distinct ERK activity response ranges are reflective of gene-specific variations in sensitivity to ERK regulation at both the transcriptional and translational levels.

Polygenic Risk, Polygenic Scores, Polygenic Indices: What Are They? What Should Be Done with Them? This episode of the https://www.spreaker.com/show/progress-educational-trust-podcast discusses the science and ethics of PGT-P – a controversial form of preimplantation genetic testing that uses polygenic scores, rather than using more traditional forms of genomic data.. The discussion – which originally took place at the PET Annual Conference – is chaired by Dr Philip Ball (science writer and broadcaster), with contributions from: ⚫ Dr Emma Meaburn (Behavioural Geneticist at Birkbeck University of London) ⚫ Dr Dorit Barlevy (Senior Researcher at Baylor College of Medicine) ⚫ Professor Angus Clarke (Emeritus Professor of Clinical Genetics at Cardiff University) PET is grateful to the British Fertility Society for supporting this discussion. PET is also grateful to Jon Nicoll, who created the opening and closing music for its podcast. Register at https://www.progress.org.uk/events/upcoming-events/ for upcoming PET events.

"Invisible" culture dishes improve the odds for IVF A clearer view for IVF: New

Selecting the healthiest #embryo is one of the most important steps in #InVitroFertilization, yet it remains one of the most uncertain. A new type of #hydrogel 🧫 dish, developed by 🇺🇸 @vanderbilt.edu researchers, offers hope for more successful #IVF. The findings are published by @spie.org.

The Origins of Preimplantation Genetic Testing This episode of the https://www.spreaker.com/show/progress-educational-trust-podcast features Professor Alan Handyside – a pioneer of preimplantation genetic testing – explaining how and why it became scientifically possible, and also legally permissible, to test the DNA of IVF embryos. This discussion – which originally took place at the PET Annual Conference – is introduced by Sarah Norcross (Director of PET) and chaired by Dr Philip Ball (science writer and broadcaster). PET is grateful to Jon Nicoll, who created the opening and closing music for its podcast. Register at https://www.progress.org.uk/events/upcoming-events/ for upcoming PET events.

PGT-A as an IVF Add-On: 25 Years of Controversy This episode of the https://www.spreaker.com/show/progress-educational-trust-podcast discusses longstanding controversies surrounding PGT-A (preimplantation genetic testing for aneuploidy) – an 'add-on' to IVF treatment whose use has been the subject of lively debate for the past 25 years. The discussion – which originally took place at the PET Annual Conference – is introduced by Sarah Norcross (Director of PET) and chaired by Dr Deborah Cohen (science writer and broadcaster), with contributions from: ⚫ Professor Karen Sermon (former Chair of the European Society of Human Reproduction and Embryology) ⚫ Dr Justin Chu (Medical Director of TFP Oxford Fertility) ⚫ James Lawford Davies (Partner at LDMH Partners) ⚫ Professor Manuela Perrotta (Leader of the Remaking Fertility initiative) PET is grateful to Remaking Fertility – an initiative based at Queen Mary University of London – for supporting this discussion.
