First, some context.
Glioblastoma (GBM) is one of the deadliest, most aggressive cancers that exist, with a median survival of only 15 months.
In GBM, 'single cell heterogeneity' are not simply buzzwords.
Rather, this immense heterogeneity is a main reason of treatment failure

Recent work demonstrated that single GBM tumors are mosaics of cells in different states, each associated with distinct genomic driver alterations.
While transitions between cell states can occur, each genetic driver favors a particular cell state.

In #JPM2023 news, $NSTG NanoString presented on January 11, 2023. Started in single-cell gene expression, now expanding into #SpatialBiology. They see a $3B+$3B market opportunity both on the NGS-based and the Imaging-based tech respectively.
The GeoMx is the NGS-based spatial biology solution, akin to the 10X Genomics Visium (and Visium HD in the future), with 25+ instruments in the pipe. CosMx is the imaging-based equivalent (Xenium in 10x portfolio), with about 80 instruments already in the pipe.
Lots of slides to describe CosMx, which is the newest and fastest growing instrument for $NSTG NanoString. High Plex, up to 1000-plex RNA assay, but also does Protein, FFPE Compatible, Tunable Throughput, Complete Informatics (AtoMx). Now 180 cummulative orders.

We are thrilled to share #Starfysh ⭐️ an auxiliary deep generative model for multi-modal analysis and integration of spatial transcriptomic (ST) datasets and histology images, and its application to heterogeneous #breastcancer tumors! 😃 tinyurl.com/hffdhvx7 1/
Incredibly fortunate to have a passionate, collaborative & talented team that didn't slow down with all the challenges of the past few years 🙏: @SiyuHe7 @YinuoJin6, @AchilleNazaret @shi_lingting and a fruitful and ongoing collaboration with @GeorgePlitas and Sasha Rudensky. 2/
Using ST, we wanted to find out if our previously observed continuous phenotypic expansion of intratumoral immune states (doi.org/10.1016/j.cell…) could be explained by the #spatialdynamics of immune cells and exposure to different environmental signals and nutrient supply? 🧐 3/
#GraphNeuralNetworks are way too cool to be left unexplored!
In a nutshell, GNNs are an exciting merger between graph theory (math) & #DeepLearning (coding).
Here's my detailed resource stack of best GNN theory explainers, videos & coding tutorials I used for my own learning.

1. This is a great place to start if you either: want to learn the basics, or enjoy reading about basic concepts explained in a well structured way.
It walks us through graphs in real world, what graphs & GNNs consist of, and how GNNs do prediction.

2. Further, this next tutorial walks us through graphs & GNNs in an intuitive manner, while also going quite deep into the specific mathematical terminology of the field.
I like this one a lot because it also includes hands-on PyTorch code at every step.

But first, some background.
Spatial molecular biology has actually been around since the 70s. @lpachter's wonderful book-like article "Museum of Spatial Transcriptomics" comprehensively discusses history, tech & methodology advances in the past 50 years.

Nevertheless, recent advances in single cell molecular technologies (brought by e.g. @10xGenomics & @AkoyaBio) have facilitated the high-throughout profiling of (groups of) single cells in their tissue context across embryogenesis, normal tissue development & disease progression.

In #biotech #stocks news, $TXG @10xGenomics is opening upwards +4% in today's trading. The company is down more than 75% in the 52-wk window. They peaked in Q1 2021 and have since then declined at a similar pace as other $XBI stocks out there.
$TXG is in the #Singlecell and #Spatial biology field. They've recently made their pivot into Spatial Biology apparent, and have both an #NGS Next-Generation Sequencing and #InSitu imaging play on it, with their #Visium and #Xenium lines respectively.
The $TXG top institutional holders include Morgan Stanley with less than 10%, followed by 3 of the heavy hitters in #biotech: UK's Baillie Gifford, Vanguard Group, and Black Rock.
In #biotech #stock news, I've added $NSTG NanoString to the list of companies I follow, one of the players in the single cell and spatial omics fields
The field is still dominated by $TXG 10X Genomics, which also have recently acquired 3 different companies in the spatial omics area, which encapsulate 60-70% of the technologies used for all the papers published using such technologies.

Almost three years of work to deliver Baysor: a tool for Bayesian segmentation of #spatial data (FISH and in-situ sequencing)! Besides the cell segmentation, we also provide a framework for segmentation-free analysis and discuss the field in general.

Pour rappel, lors des opérations de traitement du combustible usé, on sépare les différents constituants de celui-ci. D'abord, toutes les gaines et les structures du combustible partent d'un côté comme déchets de moyenne activité.
Ensuite, on extrait le plutonium pour le recycler.
Puis l'uranium, pour un recyclage qui n'est pas pratiqué aujourd'hui mais qui l'a été et le sera de nouveau dans quelques années.

As I say in the syllabus, this course basically covers all of the things I wish I'd been taught in grad school. At the same time, I've benefited immensely from so many people making their teaching materials (and software!) publicly available. This is me trying to pay it forward.
Here's a short-cut to the lecture slides and notes: github.com/uo-ec607/lectu…
I just watched @LumusVision CEO talking to @Scobleizer in his interview talking about the future of the company, future of spatial display technologies etc. One thing is very clear Lumus is not trying to be another Magic Leap / HoloLens / Meta ...
They are so clear that @LumusVision wants to position themself as Samsung's LG's of Spatial Era manufacturing the optics. I so excited to see them what Tier 1 companies they have partnered with and what they are gonna release in Q1 end (a 20° FOV light weight AR Glass)
Reflective Waveguide is the super key word ♥️ what ever the tech in Spatial at the end of the day the key component/role of it comes down to Optics Physics 😊 @LumusVision @Scobleizer 🎉
