Protocadherin-1 is expressed in the notochord of mouse embryo but is dispensable for its formation
Biochemistry and Biophysics Reports, 2021 Notochord is an embryonic midline structure that serves as mechanical support for axis elongation and the signaling center for the surrounding tissues.

Migration and Growth of Protoplanetary Embryos I: Convergence of Embryos in Protoplanetary Disks [PDF]
, 2014 According to the core-accretion scenario, planets form in protostellar disks through the condensation of dust, coagulation of planetesimals, and emergence of protoplanetary embryos. At a few AU in a minimum mass nebula, embryos' growth is quenched by dynamical isolation due to the depletion of planetesimals in their feeding zone.

The Role of Hypoxia in Development of the Mammalian Embryo [PDF]
Developmental Cell, 2009 Hypoxia inducible factor (HIF) is a transcription factor that acts in low-oxygen conditions. The cellular response to HIF activation is transcriptional upregulation of a large group of genes. Some target genes promote anaerobic metabolism to reduce oxygen consumption, while others "alleviate" hypoxia by acting non-cell-autonomously to extend and modify

Advanced Science, EarlyView.Klinefelter syndrome‐derived iPSCs provide an excellent model for studying X chromosome inactivation and functions of escapee genes during human primordial germ cell‐like cells differentiation process. Downregulation of three X‐linked genes—IGSF1, CHRDL1, and USP9X—significantly enhances the efficiency of hPGCLCs.

The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians
The Anatomical Record, EarlyView., 2023 Abstract The sclera of all vertebrate eyes is comprised of connective tissue, with some organisms developing cartilage within this tissue. A review of the cartilages that have been described in the vertebrate sclera and their anatomical relationships is discussed together with their potential homology.

X-chromosome inactivation mosaicism in the three germ layers and the germ line of the mouse embryo [PDF]
, 1982 Electrophoretic variant forms of the X-linked enzyme phosphoglycerate kinase (PGK-1, E.C.2, 7, 2, 3) have been used to examine X-chromosome mosaicism in tissues from 121/2-day post coitum heterozygous female mouse embryos.

Advanced Science, EarlyView.By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Molecular approaches to mammalian uterine receptivity for conceptus implantation
The Journal of Reproduction and DevelopmentMammalian reproduction is more inefficient than expected and embryo/conceptus implantation into the maternal endometrium is considered to be a rate-limiting process. Although extensive physiological and structural diversity exists among mammalian species,
