Antioxidant effects of quercetin in freeze-thawing process of mouse spermatogonial stem cells

The Effects of Plla Nanofiber Scaffold on Proliferation of Frozen-Thawed Neonate Mouse Spermatogonial Stem Cells

Purpose: To investigate of the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on proliferation of frozen-thawed neonate mouse spermatogonial stem cells.Materials and Methods: Spermatogonial cells were isolated from neonatal 3-6-day-old NMRI mice testes by two steps enzymatic digestion and differential plating. The isolated spermatogonial cells were divided into four culture groups: 1...

Effect of Antioxidant D-Aspartic Acid and Thawing Rate on the Freeze-Thawing Process of Ram Semen

The study was conducted to determine the influence of D-aspartic acid (D-Asp) as antioxidant supplement and thawing rates on ram sperm motility, membrane integrity, abnormality, viability, mitochondria activity, malondialdehyde and antioxidant activities, and total antioxidant capacity after freezing-thawing process. Semen samples from five mature rams (3-4 years old) were diluted with extender...

Comparison of Neonatal and Adult Mice-derived Sertoli Cells in Support of Expansion of Mouse Spermatogonial Stem Cells In vitro

Phenotypic Plasticity of Mouse Spermatogonial Stem Cells

BACKGROUND Spermatogonial stem cells (SSCs) continuously undergo self-renewal division to support spermatogenesis. SSCs are thought to have a fixed phenotype, and development of a germ cell transplantation technique facilitated their characterization and prospective isolation in a deterministic manner; however, our in vitro SSC culture experiments indicated heterogeneity of cultured cells and s...

Transfection of bovine spermatogonial stem cells in vitro

Spermatogonial stem cells (SSCs) are the only stem cells in adults that can transfer genetic information to the future generations. Considering the fact that a single SSC gives rise to a vast number of spermatozoa, genetic manipulation of these cells is a potential novel technology with feasible application to various animal species. The aim of this study was to evaluate enhanced green fluoresc...
