Assessing candidate DLX‐regulated genes in the first pharyngeal arch of chick embryos

Developmental Dynamics, EarlyView.
Abstract Background Insights into the development and evolution of asymmetrical jaws will require an understanding of the gene regulatory networks that underpin the differential morphogenesis of the maxillary and mandibular domains of the first pharyngeal arch in a variety of gnathostomes.

Structures and functions of cilia during vertebrate embryo development

Molecular Reproduction and Development, Volume 89, Issue 12, Page 579-596, December 2022., 2022
Abstract Cilia are hair‐like structures that project from the surface of cells. In vertebrates, most cells have an immotile primary cilium that mediates cell signaling, and some specialized cells assemble one or multiple cilia that are motile and beat synchronously to move fluids in one direction.

Application of a methodological framework for the development and multicenter validation of reliable artificial intelligence in embryo evaluation

Reproductive Biology and Endocrinology
Background Artificial intelligence (AI) models analyzing embryo time-lapse images have been developed to predict the likelihood of pregnancy following in vitro fertilization (IVF).

Optical matrix imaging applied to embryology [PDF]

arXiv
High-resolution label-free imaging of oocytes and embryos is essential for in vitro fertilization procedures. Yet conventional microscopy fails in this task because of aberrations and multiple scattering induced by refractive index heterogeneities inside the sample.

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes

Molecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022
Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

A Novel Nonlinear Fertility Catastrophe Model Based on Thom's Differential Equations of Morphogenesis [PDF]

arXiv
A novel fertility model based on Thom's nonlinear differential equations of morphogenesis is presented, utilizing a three-dimensional catastrophe surface to capture the interaction between latent non-catastrophic fertility factors and catastrophic shocks.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.
