Spermatogonial stem cells from domestic animals: progress and prospects

Area of Science:

• Reproductive Biology
• Stem Cell Science
• Animal Science

Background:

• Spermatogenesis, the production of spermatozoa for male fertility, depends on spermatogonial stem cells (SSCs).
• SSCs possess self-renewal and differentiation capabilities, and can be converted to pluripotent stem cells in vitro.
• This conversion offers an ethical alternative to human embryonic stem cells and bypasses the need for exogenous transcription factors.

Purpose of the Study:

• To review recent advancements in the characterization, isolation, in vitro propagation, and transplantation of spermatogonia/SSCs from domestic animals.
• To highlight the potential of these cells for future research and the development of reproductive technologies in large animals.

Main Methods:

• Review of recent scientific literature on spermatogonial stem cells in domestic animals.
• Analysis of techniques for SSC characterization, isolation, in vitro culture, and transplantation.
• Comparative assessment of progress in rodents versus domestic animals.

Main Results:

• Significant progress has been made in understanding and manipulating SSCs in domestic animals, though not yet at the rodent level.
• Established methods for germ cell transplantation facilitate in vivo and in vitro studies.
• SSCs from domestic animals show potential for generating transgenic animals and advancing reproductive technologies.

Conclusions:

• Spermatogonial stem cells from domestic animals hold significant value for reproductive technology development.
• Further exploration of SSCs is crucial for advancing large animal breeding and conservation efforts.
• The potential applications of SSCs include generating transgenic animals and overcoming infertility issues.
