Compositions, kits, and methods for preparing nutrient compositions are provided. A nutrient composition can be a food composition such as a dairy composition. A nutrient composition may be produced by an engineered cell composition. Compositions, kits, and methods for preparing engineered cell compositions for producing nutrient compositions are also provided. An engineered cell composition may comprise genetically engineered cells, such as genetically engineered mammary or mammary-like cells. An engineered cell composition can be derived from mammalian stem cells, such as non-mammary adult stem cells. Related methods of characterization, such as for characterizing the engineered cell compositions or the nutrient compositions, are also provided. |
