O texto a seguir é parte de uma chamada para publicação de
artigos em uma edição especial da revista Nature.
The environmental and ethical implications of traditional
livestock rearing, combined with an increasing global
population and demand for protein-rich nutrition, has led to
investments in alternative protein research. One emerging
approach is cellular agriculture, in which traditional ‘meat’
tissues, such as muscle and fat cells from cows, chicken
and fish, or alternative protein sources, such as algae, are
cultivated under controlled laboratory conditions. However, the
optimisation of these protocols is highly dependent on cell types,
and further development is required to make cellular agricul-
ture an economically viable alternative to traditional sources of
protein. This special issue welcomes research on improvements to
cellular agriculture protocols to maximize sustainable protein
production.
