Humanized immune system animal models and their recent applications

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this review, we provide an updated and comprehensive overview of the current state of humanized immune system animal model research. We discuss the variety of techniques used to produce humanized mice with their respective strengths and weaknesses, and evaluate the advantages and limitations of these models, including issues with incomplete immune ...

Diagnosis and management of a rare bilateral ovarian mixed germ cell tumor: a case report

open access: yesFrontiers in Oncology
BackgroundMixed ovarian malignant germ cell tumors (MOGCTs) are rare neoplasms composed of two or more malignant germ cell components, representing less than 1% of all ovarian germ cell tumors.

Mouse Germline Restriction of Oct4 Expression by Germ Cell Nuclear Factor

open access: yes, 2001
The POU-domain transcription factor Oct4 is essential for the maintenance of the mammalian germline. In this study, we show that the germ cell nuclear factor (GCNF), an orphan nuclear receptor, represses Oct4 gene activity by specifically binding within ...

Recent advances in the construction of humanized animal models and applications in translational medicine

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Substantial advances have been achieved in the development of humanized mouse models, which have proven highly valuable in evaluating cancer immunotherapies and elucidating the mechanisms of infectious diseases. There is now a growing shift in research toward larger animal models—such as pigs—that offer greater physiological similarity to humans ...

Pure yolk sac tumor of sacrococcygeal region

open access: yesAutopsy and Case Reports, 2021
The sacrococcygeal region is the most common site for the extragonadal germ cell tumors comprising seminomatous and non-seminomatous tumors. Seminomatous tumors are seminomas, and non-seminomatous tumors comprise mainly teratoma (mature and immature ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Advances in the study of tumor markers for intracranial germ cell tumors

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2020
Intracranial germ cell tumors (ICGCTs) are highly heterogeneous tumors that tend to occur in children and adolescents, and their diagnosis and treatment strategies are closely related to their pathological components.

Determining the timeline of gonadal and genital differentiation in male and female equine fetuses allows for early detection and intervention in malformations

open access: yesThe Anatomical Record, EarlyView.
Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

Overview of current European practice for the management of patients with intracranial germ cell tumours

open access: yes
Central nervous system germ cell tumours (CNS GCT) form a diverse group of tumour entities, including germinoma, yolk sac tumour, embryonal carcinoma, choriocarcinoma, teratoma, and mixed tumours.
