BRCA1 preserves genome integrity during the formation of undifferentiated spermatogonia [PDF]
Undifferentiated spermatogonia, which form shortly after birth, consist of spermatogonial stem cells and progenitor spermatogonia that maintain homeostasis.

Doxorubicin and 4-Hydroperoxycyclophosphamide Alter Mitochondrial Dynamics and miR-34 Expression in Spermatogonia and Spermatocytes In Vitro. [PDF]
ABSTRACT Doxorubicin (DOX) and cyclophosphamide (CP) are widely used chemotherapeutic agents with known gonadotoxic effects. Since miRNAs play a key role in the transcriptional regulation of spermatogenesis, they are suggested as biomarkers for male infertility.

This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

AbstractIn the seminiferous epithelium the differentiating spermatogonia proliferate following a very strict synchronous pattern, and undergo the S phase during parts of particular epithelial stages. the undifferentiated spermatogonia do not divide synchronously and display maximum proliferative activity in stages XI‐III.

About half of testicular sperm extraction (TESE) procedures in men with non-obstructive azoospermia (NOA), including men with Klinefelter syndrome (KS), are unsuccessful. To avoid unnecessary invasive surgery, biomarkers for spermatozoa were studied.

BMI1 fine-tunes gene repression and activation to safeguard undifferentiated spermatogonia fate [PDF]
Introduction: Spermatogenesis is sustained by the homeostasis of self-renewal and differentiation of undifferentiated spermatogonia throughout life, which is regulated by transcriptional and posttranscriptional mechanisms.

Set7-Mediated Repression of the HIF-1α Adaptive Response Triggers Apoptosis in Hypoxic Spermatogonia [PDF]
Background:Male infertility, often caused by oligospermia, is a major global health concern. Hypoxia is a known inducer of germ cell death, a process governed by the hypoxia-inducible factor 1α (HIF-1α).

Super-Multiplexed Label-Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation. [PDF]
Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease.
