fbs is added fbs prevents the replicating stem cells from committing suicide normally cells have a mechanism that tells them they're 00:06:29 growing in the wrong place and shuts it down this is normally a good thing and keeps different parts of the body developing properly but when cells are growing in a metal tank and not a body this warning system 00:06:42 needs to be turned off and for whatever reason fbs works almost completely universally when added to any type of cell

potential progress trap
- in vivo, an animal body has a mechanism to turn off stem cells when they are growing in the wrong place in the body. This regulates the body to grow properly.
- in lab grown meat, an artificial in vitro environment is created for the stem cells and they are encouraged to keep growing continuously (some critics compare this to cancerous growth)
- for UNKNOWN REASONS, FSB seems to prevent the mechanism from turning off cell growth, no matter what animal food species.
- the worrying thing here is that the scientific community does not know why FSB has this behavior.

Question
- What are the views of the regulatory agencies that have passed Lab grown meat on this subject?

there's one glaring problem here 00:05:11 with creating this animal-free meat it's not actually animal-free that special fbs serum i just mentioned that stands for fetal bovine serum which is collected from the dying fetuses of 00:05:25 slaughtered cows

- FBS
- Fetal Bovine Serum
- FBS
-
This is used for the growth of all kinds of stem cells, not just those from cows
- We do not know the full implications of mixing FBS from cows with all other species

an estimated 50 liters of bovine serum is needed and depending on age a single cow fetus can yield between 150 and 550 milliliters of serum that means to 00:07:33 create a single burger you need the blood of between 90 and 333 cow fetuses until a synthetic or plant-based alternative to fbs is found
- FBS volumes needed for a single lab grown burger are impractical
- an estimated 50 liters of bovine serum is needed
- a single cow fetus can yield between 150 and 550 milliliters of serum

a single muscle stem cell could be grown into one trillion muscle cell tubes

The researchers say it would make more sense to invest in increasing the efficiencies of existing livestock farms to limit their environmental footprint, which may provide greater emissions reductions sooner that this fledgling industry of lab-grown meat can.

Their life-cycle assessment of current meat-growing processes – which has yet to be peer-reviewed – found cultured meat production could emit between four to 25 times more carbon dioxide per kilogram than regular beef and all its hidden costs, depending on the techniques used.

- findings are that cultured meat production could emit between four to 25 times more carbon dioxide per kilogram than regular beef and all its hidden costs, depending on the techniques used.
- Pros
- cultured meat uses less land than herds of cattle or flocks of sheep,
- cultured meat uses less water and antibiotics,
- Cons
- laboratories to extract growth factors from animal serums,
- growing crops for sugars and vitamins.
- energy required to purify all of these broth ingredients to a high standard before they can be fed to the growing meat lumps.
- energy-intensive, extreme level of purification is needed to prevent introducing microbes to the culture.
- "Otherwise the animal cells won't grow, because the bacteria will multiply much faster,
