Some good lab news among all the turmoil! Excited about this new publication in collab with Dr. Nancy Lane. Great effort by graduate student Dave & postdoc Kun! Looking forward to presenting this & more at @asbmr.bsky.social meet next month! @ucdavishealth.bsky.social www.nature.com/articles/s41...
Basigin links altered skeletal stem cell lineage dynamics with glucocorticoid-induced bone loss and impaired angiogenesis - Nature Communications
Glucocorticoid (GC) induced osteoporosis (GIOP) remains a significant clinical problem. Here, the authors find that GCs disrupt skeletal stem cell–endothelial crosstalk via Basigin that can be targete...

Stronger bones? A @cp-cellstemcell.bsky.social study by @drambrosi.bsky.social of @ucdavis.bsky.social, funded in part by @wutsaialliance.bsky.social, shed light on how skeletal stem cells change with age and how to boost their fracture-healing abilities. humanperformancealliance.org/news/skeleta...

I feel extremely fortunate to have had the chance to learn from & work with Chuck Chan, building on some of his seminal discoveries and scientific vision. A truly 'chuckesque' manuscript by a wonderful collaborative & interdisciplinary team @cp-cellstemcell.bsky.social www.cell.com/cell-stem-ce...
Human skeletal development and regeneration are shaped by functional diversity of stem cells across skeletal sites
Ambrosi and colleagues profile human skeletal stem cells (hSSCs) across ten fetal skeletal sites and from patients throughout adulthood, identifying, mapping, and functionally testing four distinct hS...

Harnessing the diversity and potential of endogenous skeletal stem cells for musculoskeletal tissue regeneration
Abstract. In our aging society, the degeneration of the musculoskeletal system and adjacent tissues is a growing orthopedic concern. As bones age, they bec

Just a reminder that Germany was the center of scientific progress until the Nazis suppressed, drove away, or killed all the non-Nazi scientists.
8/ BOTTOM LINE: NIH BUDGET CUTS WILL MARKEDLY HURT EVERY STATE IN THIS UNION. AND RED ONES RELATIVELY MORE. REPUBLICAN & DEMOCRATIC REPS IN EACH STATE SHOULD BE LASER FOCUSED ON NOT PASSING REFORMS OR ALLOWING EXECUTIVE ORDERS TO FLY THAT HURT REVENUE GENERATION & JOB PROSPECTS. THIS HURTS PEOPLE!

Laura White@laurakwhite.bsky.social · 2y agoMade some slides for scientists to talk about what's been happening & what we should do next. There are probably many people better qualified than me to talk about these issues. If that's you, please, please, please consider holding some virtual advocacy training sessions for researchers this week.
New and first pre-print of the lab. Fun project with Nancy Lane @ucdavis.bsky.social. Feedback welcome. www.biorxiv.org/content/10.1...
Basigin Links Altered Skeletal Stem Cell Lineage Dynamics with Glucocorticoid-induced Bone Loss and Impaired Angiogenesis

A maternal brain hormone that builds bone - Nature
A brain-derived hormone, CCN3, is newly identified to have a role as an osteoanabolic factor to build bone in lactating females and in the viability of offspring.
