Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 542-549, December 2022., 2022 Schematic diagram showing RHAU can bind and unwind the G4 “knots” to modulate embryonic development and post‐natal organ function. Deficiency of RHAU gives rise to embryonic lethality, impaired organogenesis and organ dysfunction. RHAU modulates Nkx2‐5 mRNA and Yap1 mRNA at the post‐transcriptional level and facilitates the transcription of c‐Kit and ...

Have necrohormones a role in embryogenesis?
Acta Societatis Botanicorum Poloniae, 2014 The recognition of apoptosis (programmed cell death) as an accompaniment of normal development, the products released by the protoplasts undergoing self-destruction being utilized by adjacent living cells, stimulates renewed interest in Haberlandt's ...

Come together over me: Cells that form the dermatocranium and chondrocranium in mice
The Anatomical Record, EarlyView., 2023 Abstract Most bone develops either by intramembranous ossification where bone forms within a soft connective tissue, or by endochondral ossification by way of a cartilage anlagen or model. Bones of the skull can form endochondrally or intramembranously or represent a combination of the two types of ossification.

The small intestinal mucosa and its stem cells
Journal of Pediatric and Neonatal Individualized Medicine, 2016 In the first part of this review a brief summary of the embryology and histology of the gastrointestinal tract is provided. In the second part intestinal stem cells (ISCs) are discussed. Several signaling pathways play a crucial role in the crypt base in

The Biological Bulletin, 1997 Embryogenesis in hydra includes a variable period of dormancy; and this period, as well as subsequent stages through hatching, takes place within a thick cuticle that hinders observation. Thus, although the early stages of development have been well-characterized qualitatively, the middle and later stages are only poorly understood.

Acta Scientiarum: Agronomy, 2015 This study aimed to induce callus formation in Jatropha curcas L. and to evaluate the ultrastructure and cytochemical behavior of the calli. Calluses were induced with 2,4-D, picloram-PIC, kinetin (Kin) and BAP: (1) control; (2) 4.52 µM 2,4-D; (3) 9.04 ...

Assembly of embryonic and extraembryonic stem cells to mimic embryogenesis in vitro
Science, 2017 In vitro embryogenesis Pluripotent embryonic stem cells (ESCs) can differentiate into any adult cell type; however, aggregates of these cells do not mimic embryonic architecture when grown in culture.

Polarized interfacial tension induces collective migration of cells, as a cluster, in a three-dimensional tissue [PDF]
, 2021 Cells collectively migrate as a cluster in three-dimensional (3D) tissues, such as in embryogenesis and cancer invasion. Here, numerical simulations using a 3D vertex model show that polarized interfacial tension, expressing cell adhesion and cortex contractility, induces the cluster migration in the 3D space.

Embryogenesis of the peristaltic reflex [PDF]
The Journal of Physiology, 2019 Key points Neurogenic gut movements start after longitudinal smooth muscle differentiation in three species (mouse, zebrafish, chicken), and at E16 in the chicken embryo. The first activity of the chicken enteric nervous system is dominated by inhibitory neurons. The embryonic enteric nervous system electromechanically couples circular and longitudinal
