Abstract: A method for meat production by in vitro cell culture includes isolating tissue from an animal or plant source and making a cell suspension of cells, and growing the cells into a solid or semi-solid structure that mimics an animal organ by growing the cells on a food grade scaffold in a culture medium. Expression of one or more proteins in the growing cells may be increased by altering a level of one or more micro RNAs that regulate expression of the protein. Additionally, the growing cells may be co-cultured with bioengineered cells that secrete growth factors and cytokines that support the growth of the cells in situ. The co-culturing technique reduces or eliminates the need for animal-derived fetal bovine serum in the culture medium.

Abstract: A method for quantifying cells embedded in a scaffold, comprising the steps of (a) a lysing step to cause the cells to lyse using alkali or proteinase; (b) a purification step comprising centrifugation or a series of elution; and (c) a quantification step comprising the steps of (i) simultaneously carrying out probe-based qPCR on a sample reaction mix and a plurality of reference reaction mixes; (ii) collecting the signals from the probe-based qPCR products from the sample reaction mix and reference reaction mix; (iii) creating a standard curve based on the collected signals from the reference reaction mixes; and (iv) deducing the number of cells in the sample through the standard curve.
