Unlocking the mysteries of stem cells. To learn more follow @SignerLab.

Why is it so difficult to grow hematopoietic stem cells in culture? Huge increases in protein synthesis disrupt proteostasis in HSCs ex vivo. HSF1 comes to the rescue ex vivo & during aging to keep stem cells fit. Our latest now in print @CellStemCell https://t.co/mr7u3xio7M 🧵

.@UCSDMedSchool researchers unlock a way to keep lab-grown stem cells healthy, which is positive news for people who need bone marrow transplants when donor stem cells are not available. The approach may also help further aging research.

If you can’t take the heat, get out of the culture. Our latest paper in @CellStemCell uncovers how HSF1 keeps stem cells fit in a dish. 🔥💪 https://t.co/wPbW4Uti2w

DOUBLE THE @NIH BUDGET. Science is critical for our economy, health & security. Science is conquering #COVID and is essential for tackling future pandemics and other diseases. But science is woefully underfunded. NOW IS THE TIME.

[Robert Signer @SignerLab]

While we’re focused on the BIG discoveries that enabled the rapid development of the #COVID vaccine, let’s not forget the engine that powered it: trainees, long days, failed experiments, rejection, persistence, resiliency. This is progress. This is science.

Why do some genetic disorders present in kids and others in adults? Our new paper w/@Magee_Lab reveals that BIG changes in protein synthesis during ontogeny sensitize distinct hematopoietic cell types to a ribosomal mutation in an age-dependent manner. https://t.co/zby3tRCaBa

Attention hematopoiesis community: Have you ever been confused about which set of markers to use to identify HSCs and MPPs? We hope to bring clarity & unity to the field. Tune in to this important @ISEHSociety webinar on Tuesday, November 10th!

ERADicating stem cells from their niche. Our News & Views on exquisite new work from @XiChenLab in @NatureCellBio on how proteostasis regulation by the ERAD pathway influences the interaction of HSCs with their perivascular niche in the bone marrow. https://t.co/BP3nkATATl

Why do ribosomal mutations only impair certain cell types? Developmental stage-specific changes in protein synthesis differentially sensitize hematopoietic stem cells and erythroid progenitors to impaired ribosome biogenesis. New preprint w/@Magee_Lab. https://t.co/DrNmrBdxhJ

Humbled to be included with these outstanding scientists. Thank you @LLSusa, @TheMarkFdn & @AllenInstitute for supporting our innovative research targeting protein synthesis to treat blood #cancers.

The @SignerLab is hiring Postdocs! Our curious and creative team @UCSDHealth investigates how the proteostasis network is uniquely configured to promote stem cell function and longevity, and encompasses new therapeutic targets in cancer. Info: https://t.co/f1GUZYXoTA. Please RT!

DNA isn’t destiny. Stem cell identity and function depend on the epitranscriptome, translational control and protein degradation to regulate proteome content, quality & complexity. New review on post-transcriptional control of stem cells in @CellStemCell. https://t.co/qQFXcSWg6d

Modest declines in proteome quality impair hematopoietic stem cell self-renewal https://t.co/U9hCIzhRxz

Misfolded proteins are associated with Alzheimer’s, Parkinson’s and other neurodegenerative diseases. New research reveals that misfolded proteins also impair stem cell function and tissue regeneration. https://t.co/YUJ5RhIBBB #stemcell #proteostasis #sparkjoy

The Science of Tidying Up: Stem cells depend on low protein synthesis to prevent the biogenesis of misfolded proteins. https://t.co/N4Ez6k9tQ7
