Sheep-derived cell immortalization through the expression of cell cycle regulators and biological characterization...

Area of Science:

• Veterinary Medicine
• Cell Biology
• Animal Science

Background:

• Sheep are vital livestock for wool and meat, but sheep-derived cell lines are scarce compared to human and mouse models.
• Limited availability of sheep cell lines hinders research in veterinary medicine and animal science.

Purpose of the Study:

• To establish and biologically characterize immortalized cell lines derived from sheep.
• To overcome the scarcity of sheep cell lines for research applications.

Main Methods:

• Utilized the K4DT method, introducing mutant cyclin-dependent kinase 4, cyclin D1, and telomerase reverse transcriptase into sheep muscle-derived cells.
• Employed the Simian virus 40 (SV40) large T oncogene for cell immortalization.
• Characterized the biological properties of the established immortalized cells.

Main Results:

• Successfully immortalized sheep muscle-derived fibroblasts using both the K4DT method and SV40 large T antigen.
• The established cell lines exhibited biological characteristics similar to ear-derived fibroblasts.
• Confirmed the successful creation of a novel sheep cell line resource.

Conclusions:

• The K4DT method and SV40 large T antigen effectively immortalize sheep muscle-derived fibroblasts.
• The developed cell lines serve as a valuable cellular resource for advancing veterinary medicine and cell biology research.
• This study addresses the need for more sheep-derived cell lines, facilitating future scientific investigations.
