We find that heterogenous MAPgels support vasculogenesis! Here we only studied binary mixtures. Imagine what higher order mixtures can do!

Congratulations Alex on a job well done.

Tatiana Segura @seguralab.bsky.social · Dec 8

To engineer ways to have nascent vessels transverse HMPs rather than wrap around them Alex turned to heterogenous MAP gels composed of different ratios of HMPs that have different biochemical composition.

An early feature of vasculogenesis is vacuole formation. Here we show that #MAPgel can support vacuole formation but only in MAPgel composed of #HMP that have 3D pore sizes of <20pL. But, after 24-hours the next stages of vasculogenesis do not continue and the cell instead spread along the HMP.

New publication ⚠️This study was led by the✨Dr. Alexa Anderson✨, who graduated with her PhD back in 2023. Here she investigated the process of vasculogenesis (not sprouting angiogenesis) in #MAPgel. She did a very comprehensive an amazing job! 🧵

This was such a #proudPI moment! It is truly an honor to be part of @juhisamal.bsky.social 's mentoring team. It's the best to see great people become great PIs. It's not enough to be a great scientist.

juhisamal.bsky.social @juhisamal.bsky.social · Nov 30

Couldn’t possibly overstate the role of my postdoc mentor Tatiana @seguralab.bsky.social in my academic career! She’s a forever champion of her trainees and everything I want to be for my mentees! Also the hugs are stellar! 😂 Exhibit A (signing my faculty job offer letter) here was followed by one!💕

Based on my two posts (I know you all probably already know this), GIFs do not work in bsky but videos do! This is again NPCs growing in an RGD/IKVAV modified #MAPgel! Amazing work by former graduate student Katrina Wilson! onlinelibrary.wiley.com/doi/10.1002/...

Thank you Michaela! So nice to be highlighted! The Duke BME community is indeed stellar ⭐

Michaela Martinez @michaelakmartinez.bsky.social · Nov 13

Duke BME has a stellar community of biomaterials experts, including @seguralab.bsky.social. Her team develops biomaterials that can harness the body’s own ability to repair itself. One of the applications of this work is in the brain, potentially limiting issues caused by strokes.

You can find this and all other manuscripts in the special issue in our MAP timeline (which we try hard to keep updated) seguralab.duke.edu/what/highlig... All articles in this issue have a midnight blue background😀

MAP stands for Microporous Annealed Particles, and it’s a biomaterial we invented with special properties that make it stand out in a class of its own.

I am so behind on posts and really wanted to finish positing about the special issue I edited for Advanced Healthcare Materials. I got through half the papers in X... onlinelibrary.wiley.com/doi/10.1002/... I do not think I will finish that project, too much work, but will start with new papers 😆.
