PAX2+ Mesenchymal Origin of Gonadal Supporting Cells Is Conserved in Birds

Frontiers in Cell and Developmental Biology, 2021
During embryonic gonadal development, the supporting cell lineage is the first cell type to differentiate, giving rise to Sertoli cells in the testis and pre-granulosa cells in the ovary. These cells are thought to direct other gonadal cell lineages down

Development and Conservation of Gonadal Primordial Germ Cells for Preservation of Local Chicken in Indonesia [PDF]

, 2017
One of the ex situ conservation techniques for poultry that recently developed was to collect primordial germ cell (PGC) or gonadal primordial germ cell (gPGC) that isolated from embryo development.

Use of quantitative real-time PCR to select reference genes in the testis and ovary of Apostichopus japonicus during the breeding period

Aquaculture Reports, 2022
Gonads play a critical role in the reproduction of sea cucumbers, and their development is regulated by a large number of genes. To date, the ideal reference genes (RGs) for studying sea cucumber gonadal development have not been reported. In this study,

Identification and differential expression of piRNAs in the gonads of Amur sturgeon (Acipenser schrenckii) [PDF]

PeerJ, 2019
Objective Sturgeons are considered living fossils, and have a very high conservation and economic value. Studies on the molecular mechanism of sturgeon gonadal development and sex differentiation would not only aid in understanding vertebrate sex ...

Transcriptome analysis of genes related to gonad differentiation and development in Muscovy ducks

BMC Genomics, 2020
Background Sex-related genes play a crucial role in gonadal differentiation into testes or ovaries. However, the genetic control of gonadal differentiation in Muscovy ducks remains unknown.

Combined analysis of embryonic gonadal development differences of mulard duck and muscovy duck using long non-coding RNAs and mRNAs

浙江大学学报. 农业与生命科学版, 2023
The purpose of this study was to screen key mRNAs and long non-coding RNAs (lncRNAs) that affect gonadal development in duck embryos and to explain scientifically gonadal development defects in the mulard duck. Three male embryonic gonadal tissues of the
