Lab meat: Will Canada get left behind?
Cultivated meat — real protein grown directly from animal cells — is officially moving out of the lab and into commercial production. While U.S. producers are scaling up, Canada is on a much more cautious timeline. CBC News’ Johanna Wagstaffe looks into the science behind cellular agriculture and the regulatory framework that novel foods must navigate before hitting Canadian shelves.

Green Synthesis of CdTe Quantum Dots and Their Effect on Human and Animal Cells - Cytology and Genetics

Abstract Since the nanoscale in combination with luminescent properties and prospective applications in different fields of optoelectronics and biomedicine is stimulating a growing interest towards research in the area of cadmium telluride (CdTe) quantum dots (QDs), the method of “green” synthesis of CdTe QDs with the use of the Pleurotus ostreatus mycelium culture as a biological matrix has been developed. The study of their physical and chemical characteristics has shown that the synthesized CdTe QDs are characterized by a crystalline structure and a predominantly spherical morphology and are 3–8 nm in size with the luminescence maximum within the 340–370 nm range. The study of their effects on different types of mammalian cells has shown that CdTe QDs have dose-dependent effects on mouse endothelial cells and human and rat erythrocytes, T- and B-lymphocytes, colorectal cancer cells (Colo 205), and human breast cancer cells (MCF-7). In particular, suppression of proliferative indices of endotheliocytes and an increase in the count of dead cells were observed, which indicates the cytotoxic action of nanocrystalline CdTe and its antiproliferative effect on endothelial cells. At the 5 µM concentration, CdTe QDs exhibited hemolytic activity, due to their action on erythrocytes, and affected adhesive contacts and cancer cell survivability. At the same time, human breast cancer cells (MCF-7) were more sensitive to their action. The data obtained are exclusively important for the understanding of mechanisms underlying the toxicity of CdTe QDs and for their future application in biological and biomedical research.

Fact Check: Lab-Grown Meat Is NOT Cultivated From Cancerous Or Pre-Cancerous Animal Cells

Is lab-grown meat cultivated using cancerous or pre-cancerous animal cells? No, that's not true: Cell-cultured meat is cultivated using animal cells that have been modified to replicate indefinitely. Cell-cultured or lab-grown meat is regulated in the U.S. under the same...
