SALL4 is expressed by undifferentiated spermatogonia in postnatal day 7 and postnatal day 14 testes.

open access: yes, 2013
(A–F) SALL4 expression is restricted to LIN28 positive undifferentiated spermatogonia at PND 7 and PND 14. (G–L) SALL4 expression is restricted to PLZF positive undifferentiated spermatogonia at PND 7 and PND 14. Scale bars = 10 µm.

Long-term culture of undifferentiated spermatogonia isolated from immature and adult bovine testes [PDF]

open access: yes, 2018
ウシ精巣に由来する多能性生殖幹細胞株の樹立 --精子になるはずのものが多能性細胞に--. 京都大学プレスリリース. 2018-03-08.Undifferentiated spermatogonia eventually differentiate in the testis to produce haploid sperm. Within this cell population, there is a small number of spermatogonial stem cells (SSCs).

Igf binding proteins protect undifferentiated spermatogonia in the zebrafish testis against excessive differentiation [PDF]

open access: yes, 2016
Insulin-like growth factor (Igf) binding proteins (Igfbps) modulate the availability of Igfs for their cognate receptors. In zebrafish testes, Igf3 promotes the proliferation and differentiation of type A undifferentiated (Aund) spermatogonia, and igf3 ...

FSH regulates RA signaling to commit spermatogonia into differentiation pathway and meiosis

open access: yesReproductive Biology and Endocrinology, 2021
Background Spermatogenesis is a complex process that is controlled by interactions between germ cells and somatic cells. The commitment of undifferentiated spermatogonia to differentiating spermatogonia and normal spermatogenesis requires the action of ...

Loss of Ubiquitin Carboxy-Terminal Hydrolase L1 Impairs Long-Term Differentiation Competence and Metabolic Regulation in Murine Spermatogonial Stem Cells

open access: yesCells, 2021
Spermatogonia are stem and progenitor cells responsible for maintaining mammalian spermatogenesis. Preserving the balance between self-renewal of spermatogonial stem cells (SSCs) and differentiation is critical for spermatogenesis and fertility ...

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Mouse Chd4-NURD is required for neonatal spermatogonia survival and normal gonad development

open access: yesEpigenetics & Chromatin, 2022
Testis development and sustained germ cell production in adults rely on the establishment and maintenance of spermatogonia stem cells and their proper differentiation into spermatocytes.

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

open access: yesAnimal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Sertoli cell and spermatogonial development in pigs

open access: yesJournal of Animal Science and Biotechnology, 2022
Background Spermatogenesis is an intricate developmental process during which undifferentiated spermatogonia, containing spermatogonial stem cells (SSCs), undergo self-renewal and differentiation to generate eventually mature spermatozoa. Spermatogenesis

A New Paradigm: 46 Structural Cell Types Function as Environment‐Supporting Innate Immune Cells, With Endothelial and Vascular Smooth Muscle Cells as Key Prototypes

open access: yesiNew Medicine, EarlyView.
ABSTRACT The scope, organization, and biological significance of innate immune functions across structural cell types remain poorly defined. To address these fundamental knowledge gaps, we analyzed experimental data of transcriptomes generated by our group and others.
