Animal Testing: A Necessary Evil for Medical Breakthroughs
As scientists push to develop alternative methods to replace animal testing in research, it's becoming increasingly clear that abandoning this practice altogether may not be the best course of action. Dr. Robin Lovell-Badge and Prof Emma Robinson argue that while new approach methodologies (NAMs) show promise, they are still limited by their reliance on animal-derived products.
Currently, many NAMs, such as organoids and organs-on-a-chip, rely on a crucial growing matrix called matrigel, which is derived from mouse sarcoma tumors. These technologies also often require foetal bovine serum, containing essential growth factors that synthetic alternatives cannot currently replace.
While increased investment in NAMs may help identify and develop alternative products, it's unrealistic to expect these alternatives to emerge quickly enough to completely replace animal testing. Biology is complex, and understanding the intricacies of complex diseases such as developmental changes, aging, or interactions between biology and environment will likely require further research involving living organisms.
Moreover, premature abandonment of animal testing could demotivate highly skilled and well-trained animal technologists who are crucial to many studies. The loss of these experts would affect not only the UK's competitiveness but also the wellbeing of animals in research.
The authors suggest that aspects of NAMs could be sped up for simpler assays such as toxicity and pharmacokinetics, where regulations already require animal testing. However, even with advancements in NAMs, it's likely that some areas of science will remain reliant on animal testing for years to come.
Ultimately, finding a balance between the use of animals in research and the development of alternative methods is key. Strict regulation and continued investment in NAMs may be necessary to drive progress towards an animal-free future while ensuring that medical breakthroughs continue to emerge.

. I mean, organoids and organs-on-a-chip are still pretty new tech and while they show promise, we can't just expect them to magically replace every single aspect of animal testing right away. What if these alternative methods require even more resources than our current methods? It's like trying to build a Lego castle without the instructions 
. We need to find that balance between investing in NAMs and making sure we're not sacrificing medical breakthroughs in the process.
It's not like we can just magic up a new way of doing things overnight. And what about all the people who work with animals in research - they're basically getting left behind? 
It's like, we need to find a balance between being animal-friendly and still making progress on diseases and stuff. I don't think we can just switch everything off to animal testing right now. We gotta keep investing in these new alternative methods, but also make sure we're not just leaving the people who work with animals behind. 
I think its pretty wild that we're still debating whether or not animals have a place in medical research. Like, we're making so much progress with these new techs like organoids and organs-on-a-chip, but we're also acknowledging the limitations of those methods too. Its all about finding that balance, right? I mean, I'm not saying animals should be used for everything, but at the same time, abandoning animal testing altogether seems pretty unrealistic... especially when you consider how many people are trained to do this work and would lose their jobs.
. So we're stuck between a rock and a hard place, right? We gotta keep using animals for testing or risk losing the expertise of these awesome scientists 
. And let's be real, animal-derived products are still our only option for now 
.
. Like, why not use these new NAMs for simple tests and save the animals (and experts) for more complex stuff? 
. We can't just ditch animal testing cold turkey - it's too much of a risk to our medical progress 
.
. Maybe then we can create an animal-free future that's still got science on its side 
! 
, dont think we can skip steps in science, biology's too complex 
, what about all those experts who know animal testing? 
, demotivating them and losing our competitive edge isn't cool 
, strict reg's and more funding for NAMs is probably the way forward 
and we cant just skip over the hard stuff 
its like trying 2 solve a puzzle w/o even lookin @ the pieces 
- NAMs are promisin, but they got limitations too 
- im all 4 strict regulation tho 
wanna make sure thats R&D is done w/ integrity & safety first 
. We need to keep investing in these new approaches, like organoids and organs-on-a-chip, but let's not expect them to come out of nowhere, you know? 
... we can't just lose them. It's like, if we abandon animal testing too quickly, we'll be left with a big hole that's hard to fill 
.
. Let's keep pushing forward with NAMs, but also make sure we're regulating things properly so we don't have any big issues down the line 
.
And what's the point of having highly skilled animal technologists if they're not needed for actual research? It's time to let those smart folks move on to more exciting jobs, like... I don't know, playing video games or something. 
but let's be real, biology is super complicated and we need more time to figure out these alternative methods before we get rid of animal testing altogether 
gotta find a balance, right?
. It's like when you're trying to get to work and your phone is out of battery - you know you need to charge it ASAP, but then again, it's hard to keep going without a charger 
. Similarly, NAMs are like that charger, but they need some time to mature. And what about all the people who've dedicated their lives to animal research? We can't just leave them high and dry 
. We can't just ditch animal testing cold turkey, biology is too complex 
I don't think it's that black & white, you know? Animal testing has been a thing for ages, but now we're being told we gotta ditch it altogether? 
Maybe it's not an either-or situation, but more like... how can we speed up the process while still being kind to those who work with animals? 
. And can you imagine if we lost all the experts who have been doing this work for years? That would be a huge loss 
. I think we need to find a way to balance progress with compassion 
. Maybe it's not about getting rid of animal testing completely, but more about making sure it's done in a responsible and humane way 
The thing I find most frustrating is that animal techs are being demotivated just so we can avoid animal testing. Like, what's wrong with being an animal scientist?! It's a real job! We should be supporting people in it, not letting them go because of hypothetical alternatives 
. And honestly, I think its kinda refreshing to see people like Dr Lovell-Badge and Prof Robinson having this conversation - its not as easy as saying 'lets just ditch animal testing' because biology is wild 
. And what about all those skilled animal techs who are super important to their studies? Losing them would be a major setback, you feel?
? We can use NAMs for simpler stuff and still keep the more complex research going with animals. Does that make sense?
... maybe that's the middle ground we need
