Allantois and placenta as developmental sources of hematopoietic stem cells

The International Journal of Developmental Biology, 2010
While the aortic region, the para-aortic splanchnopleura/aorta-gonads-mesonephros (P-Sp/AGM) is currently considered as the source of definitive hematopoietic stem cells during development, the mouse placenta has been found to generate large numbers of these cells and to remain functional in this respect for a longer period than the P-Sp/AGM. The fetal

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

Advanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

A comprehensive embryonic staging series of the turtle Trachemys scripta

Developmental Dynamics, Volume 255, Issue 3, Page 260-320, March 2026.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Urachal Mucinous Cystic Tumour of Low Malignant Potential With Incidental Clinical Presentation: A Case Report With Clinicopathologic Features and Review of the Literature

Case Reports in Pathology, Volume 2026, Issue 1, 2026.
Urachal mucinous cystic tumour of low malignant potential (MCTLMP) is a rare cystic epithelial neoplasm of urachal origin, with fewer than 50 cases described as such in the English‐language scientific literature. This case report describes an instance of urachal MCTLMP discovered incidentally in a 59‐year‐old female patient following the performance of

Initial development of bovine placentation (Bos indicus) from the point of view of the allantois and amnion

, 2009
The aim of this study was to perform a morphological characterization of the initial bovine placental development, between 20 and 70 days post-insemination (p.i.), with emphasis on the differentiation of the allantois and amnion.

Cdx2 contributes to the expansion of the early primordial germ cell population in the mouse [PDF]

, 2012
Cdx gene products regulate the extent of axial elongation from the posterior growth zone. These transcription factors sustain the emergence of trunk and tail tissues by providing a suitable niche in the axial progenitor zone, via regulation of Wnt ...

A case of urachal carcinoma – Reporting the less reported

Journal of Current Research in Scientific Medicine
Urachal carcinoma is a rare and aggressive type of bladder cancer that originates from the urachus, a fibrous tissue left over from the allantois, connecting the bladder to the umbilicus.
