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.

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! 🧵 onlinelibrary.wiley.com/doi/10.1002/...

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.

Noah is thrilled to find a home in the Segura lab, where he looks forward to merging his two previous interests – brain characterization & cell based therapeutics – by utilizing customized MAP hydrogels in stroke recovery. You can learn more about Noah at: seguralab.duke.edu/team/noah-ca...

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/...

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 😆.
