           Morning everyone! Pleased to share a detailed protocol of our bone marrow organoid approach in @NatureProtocols :  https://t.co/nh050lwgbx.

             Finally finally a big thank you to everyone who has engaged with and showed an interest in implementing the system. I am hopeful that we can make big strides forward as a community as these types of systems advance. Thank you to patients + funders!

             Finally I am likely to close this account because of... well... everything... so please follow me over in @abattacks.bsky.social. If you're interested in implementing please join:  https://t.co/LaqIH43hOO  Where we help troubleshoot + share protocols etc.

             A lot of the major therapeutic challenges and many interesting questions are around clonal evolution, chemoresistance etc. To address those well we need longer lived, 'stable' cultures - we see a decline in complexity over time in our static cultures. Watch this space!

             I'll end on quoting @kellystevenslab 'It's not about how far we've come, but about how far we have left to go.' I hope you will agree this is a big step forward, but there are still challenges that I am excited to tackle (funding pending of course).

             ... you can build in a lot of complexity and work out strategies to retain throughput and scalability.

             We present what we believe is a highly complex in vitro model that showcases the potential of human organoid systems. By adapting granular microgels pioneered by colleagues in the bioengineering field (e.g. J Burdick and others), I think we also show that...

             Finally that helps us identify an inflammatory pathway (MIF) which we think underpins myeloma mediated inflammation. We show that inhibiting this in myeloma-comBO chimeroids ameliorates markers of inflammation.

             We then apply this system as a pre-clinical model to study multiple myeloma - showing that we support primary myeloma cells (notoriously difficult to culture ex vivo) and capture hallmarks of their extensive interactions with bone marrow niches.

             In this manuscript we address these to present comBO: a combined bone and lympho-myeloid bone marrow organoid system (I know the acronym is a bit of a reach, but it's stuck now).

             On to the science! Despite recent advances in developing bone marrow organoid systems (our own work in @CD_AACR (2023) and @NatureProtocols (2024) + Frenz-Weissner paper (2024), the major challenges (as we see them) remained:
