2D cell lines cannot reflect patient variability, and mouse models often fail on being a reliable translational model
Vlachogiannis et al., built a living biobank of patient-derived organoids (PDOs) from heavily pretreated cancer patients enrolled in phase I/II trials.
And they very accurate🧵🪡

From where does a CRO actually get its clients?
In biotech, every purchase carries risk (delays, rework, lost data...) and teams rarely pick suppliers or partners from ads alone.
The number 1 source of leads is referrals.
But if that's mostly customer service, how can marketing help? ⬇️⬇️

A CRO might say:
“We deliver reports in 5 days.”
But if accuracy is the client’s top concern, that sounds rushed, not reliable.
List speed only when time is the bottleneck.

An ad says: “We’re experts.”
A case study proves it.
A white paper shows why it matters.
The goal: move readers closer to believing you're the right choice.

Been there, done that.
But now it's time to move on.
Next time try numbers over adjectives:
"Get results 2× faster than with standard LC-MS.”

When writing copy, start by asking yourself:
“How does this help my customer?”
Then build it backwards.
You’re not selling “a reliable workflow.”
You’re selling confidence when meeting the FDA.

Everyone says “reliable data.”
But in science, proof is the best adjective.
Try:
“<2% CV across replicates.”
“99.8% recovery rate for small molecules.”

Top 6 things that shocked me when researching in gene editing #WorldCRISPRDay
- Sometimes editing efficiency can be as low as 5%, yet you will still see a change in phenotype.
- The genome is truly strong and delicate at the same time.
- Chromatin folding can make or break your target.

“Automate your data processing pipeline”
Say
“Turn a week of data analysis into a one-hour workflow.”
Scientists don’t buy automation.

A great one:
“Deliver your mRNA vaccine with 95% efficiency.”

I see many young companies going all-in on social media.
They post daily, chase visibility, and measure likes.
But the problem with social media is that posts are temporary
People will only find it on their feeds for a few days (1-2 weeks, if you're lucky).
However.. a web page is permanent.

A few years ago, I was working on a miRNA project to inhibit an appetite pathway in the brain.
I remember having a lot of doubts about what was possible:
“Can I measure functional activity in this specific brain region?”
“Is there a protocol to quantify miRNA-mRNA?”

A lab looking for device X is not looking for the fastest device on the market.
They're looking for solutions.
If time is an issue for them,
That’s when you should list speed as a benefit.
