Researchers on the Roslin Institute, a part of the College of Edinburgh, have developed a line of self-renewing pig fats cells that might help large-scale cultivated meat manufacturing by enabling constant, environment friendly era of fats tissue with out genetic modification.
“These fats cells have the potential to be a game-changer within the subject of cultivated meat”
The cells, designated as FaTTy, are derived from early-stage pig stem cells and exhibit the uncommon potential to each proliferate indefinitely and reliably differentiate into fats cells. This capability addresses a long-standing technical barrier in cultivated meat manufacturing, the place most animal stem cells lose their potential to turn into fats cells over time, making scalable fats manufacturing troublesome.
“These cells not solely develop indefinitely but additionally retain their potential to turn into fats at such excessive effectivity—one thing we’ve by no means seen earlier than in livestock stem cells. It opens the door to new prospects in cultivated meat and past,” famous Dr Tom Thrower, lead researcher on the Roslin Institute.

The analysis, published in NPJ Science of Food, concerned isolating stem cells from 5 piglets and cultivating them below numerous circumstances. Just one cell line demonstrated the required stability and self-renewal properties with out requiring gene modifying or animal-derived dietary supplements. Over a 40-day interval, the cells have been proven to constantly accumulate fats, which was visualized utilizing fluorescent markers.
Chemical evaluation revealed that the lab-grown fat intently resembles pure pig fats in composition, with barely elevated ranges of monounsaturated fat, a profile that will attraction to health-conscious shoppers and meals builders.
Open entry to speed up mobile agriculture
Fats stays a important part within the sensory profile of meat merchandise, offering taste and texture. Its dependable replication in cultivated codecs is taken into account important for market viability. The brand new FaTTy cell line might provide a viable pathway for producing animal fats at scale for integration into hybrid or totally cultivated meat products.
The cell line is at the moment being made out there to tutorial and industrial companions to help additional analysis into mobile agriculture and fats tissue engineering.
Professor Xavier Donadeu, principal investigator on the Roslin Institute, acknowledged, “This discovery represents a really particular growth. These fats cells have the potential to be a game-changer within the subject of cultivated meat, and assist make this a actuality within the very close to future.”
