New review on the importance of intestinal epithelial-mesenchymal crosstalk - from development and homeostasis through to regeneration to neoplasia. Excellent collaboration with @FrancesJEngland, Manquiang Lin and Michael Sigal https://t.co/oqmDV9RraC

So excited to get underway on CRC-STARS - a brilliant collaborative effort to improve therapies for colorectal cancer. Thanks to all the colleagues, patients and funders for helping us get here! https://t.co/G58NqEW7Yw

The CRC-STARS team will learn more about how bowel cancer behaves so that it can potentially be treated in a more personalised way

Being forced to read the rantings of a megalomaniac is too much for even a very occasional user of this site. I’m done. See you at @leedham-simon.bsky.social

🚨RTs please🚨 Apply to join our spatial hackathon, full details below and the call is looking for applicants across a range of computational, biological and clinical disciplines. 👇👇
Applications for our Spatial Biology Data Challenge, in partnership with @MRCMouseNetwork, are now open! Collaborate with and compete against teams of data and cancer experts to overcome the challenges of using large-scale spatial biology data. Apply by 16 September.

Inflammatory bowel disease (#IBD) increases bowel cancer risk: 1/3 of patients with low grade dysplasia (LGD) will get cancer. This risk is very high &reason for treatment. But also major conundrum b/c 2/3 patients with LGD won't get cancer. Can we know who is really at risk? 1/3

Through the adaption and application of a range of these maths tools, we demonstrate that immune and stromal cell interactions change with pathological state, as a rectal cancer emerges from a paired benign adenoma.

Have you ever generated a beautiful spatial biology image but had no idea how to biologically interpret it? So did we! We have spent 2 years working with a wonderful group of mathematicians to develop a suite of spatial descriptors to quantify cell interactions from multiplex IHC

Pleased to present latest lab preprint showing how pathological disruption of intestinal BMP gradients gives rise to ectopic stem cell niches through stromal remodelling. https://t.co/9mFqg49uSD

Our new study demonstrated real world difficulties in applying histological stratification tools in colitis-associated dysplasia, which remains very challenging. Congrats to @NadiaNasreddin who coordinated a wonderful group of expert pathologists. https://t.co/iLFlgAFjJY

Immigration of skilled workers supports both the NHS and British science. Both have already been negatively impacted by Brexit. This knee jerk bill will prevent essential recruitment into these professions and further degrades British success stories.
The level of net migration is too high. Today we’re announcing a new plan to reduce immigration and curb the abuse of our visa system. Here is what we're doing 🧵👇
