Placenta: an old organ with new functions

Frontiers in Immunology
The transition from oviparity to viviparity and the establishment of feto-maternal communications introduced the placenta as the major anatomical site to provide nutrients, gases, and hormones to the developing fetus. The placenta has endocrine functions,

An Adenoviral‐Vectored Tp0326 Vaccine Elicits Robust Functional Antibodies to Prevent Treponema pallidum Dissemination in a Rabbit Model

Advanced Science, EarlyView.
Vaccination promotes cellular infiltration into primary lesions and effectively inhibits T. pallidum dissemination to distal organs. Notably, transfer of lesion tissue from immunized animals fails to establish infection in naive recipients, confirming specific protective immunity.

DNA Methylation Signatures in Paired Placenta and Umbilical Cord Samples: Relationship with Maternal Pregestational Body Mass Index and Offspring Metabolic Outcomes

Biomedicines
An epigenomic approach was used to study the impact of maternal pregestational body mass index (BMI) on the placenta and umbilical cord methylomes and their potential effect on the offspring’s metabolic phenotype.

Updates on placental studies in bitches [PDF]

Ciência Rural
: The placenta, despite being a temporary organ, is essential for the development and survival of the conceptus. During pregnancy, it performs essential functions, such as nutrition, protection, circulation, excretion, and secretion.

Generation of precision-cut slice cultures of human placenta.

, 2022
We present a protocol to generate an advanced ex vivo model of human placenta. We use a vibrating tissue slicer to obtain precision-cut slices representative of the entire thickness of human placenta.

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

Advanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.

Giant chorioangioma of the complicated placenta with retroplacental hematoma. Presentation of a patient

Acta Médica del Centro, 2016
The abnormal proliferation of vessels derived from the placenta is known as chorioangioma, although it is the most common placental benign tumor not trophoblastic of the placenta occurs in a frequency as low as 1% of pregnancies.

Mitochondrial Transformations in the Ageing Human Placenta

, 2020
Mitochondria play a key role in homeostasis and are central to one of the leading hypotheses of ageing, the free radical theory. Mitochondria function as a reticulated network, constantly adapting to the cellular environment through fusion (joining ...
