Pre‐oviposition development of the brown anole (Anolis sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Mullerian adenosarcoma-like tumor arising from an extragonadal germ cell tumor: Case Report and Literature Review

open access: yesHuman Pathology Reports
Extragonadal germ cell tumors (GCTs) are rare neoplasms, accounting for 1–5 % of all germ cell tumors. Mixed germ cell tumors are neoplasms with more than one GCT component.

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Reversible programming of pluripotent cell differentiation [PDF]

open access: yes, 2000
We have undertaken an in vitro differentiation analysis of two related, interconvertible, pluripotent cell populations, ES and early primitive ectoderm-like (EPL) cells, which are most similar in morphology, gene expression, cytokine responsiveness and ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Study of germ cell tumors of ovary and associated immunohistochemistry [PDF]

open access: yesJournal of Clinical and Basic Research
Background: Females have a 6–7% lifetime risk of developing ovarian tumors. Ovarian cancer is often termed a “silent killer” due to its frequent diagnosis at advanced stages.
