The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 6, Page 325-340, September 2025.The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,

Zebrafish as a Versatile Model Organism: From Tanks to Treatment
MedComm – Future Medicine, Volume 4, Issue 3, September 2025.The zebrafish, with its optical transparency and genetic tractability, serves as a versatile in vivo platform for biomedical research. This review underscores its significance in modeling a wide spectrum of human diseases—from cancer to metabolic disorders—and in leveraging cutting‐edge technologies like CRISPR and TALENs.

Developmental Dynamics, Volume 254, Issue 8, Page 887-901, August 2025.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Embryo-mediated genome editing for accelerated genetic improvement of livestock
, 2021 Selecting beneficial DNA variants is the main goal of animal breeding. However, this process is inherently inefficient because each animal only carries a fraction of all desirable variants. Genome editing technology with its ability to directly introduce

Arguing Along the Slippery Slope of Human Embryo Research
, 1996 One frequent argument in the debate over federal funding of human embryo research is the slippery slope argument. Slope arguments can be of several types: either logical, empirical, or full (a combination of logical and empirical slope arguments, with an

Embryonic stem cells: modelling effects ofearly embryo environment
, 2013 The Developmental Origins of Health and Disease (DOHaD) hypothesis proposes that embryonic environment can induce permanent changes in metabolism during development, increasing the risk of disease in adults. Adverse environments during critical stages of

Micro-magnetic resonance imaging study of live quail embryos during embryonic development [PDF]
, 2011 Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place.

The Spare Embryo: A Red Herring in the Embryo Experimentation Debate
, 1993 Whenever embryo experimentation is discussed the question of whether it is preferable to use spare or specifically produced ('research') embryos for destructive embryo experimentation always enters the debate at some stage.

Embryo Research: The Ethical Geography of the Debate
, 1997 Three basic political positions on embryo research will be identified as libertarian, conservative, and social-democratic. The Human Embryo Research Panel will be regarded as an expression of the social-democratic position.
