Ep. 199: “Regeneration in Zebrafish” Featuring Dr. Ken Poss

Guest:

Dr. Ken Poss is the James B. Duke Professor of Cell Biology and Head of the Duke Regeneration Center at Duke University. His lab investigates the initial morphogenesis and injury-induced regeneration of several tissues in zebrafish. He is also President of the newly-founded International Society for Regenerative Biology.

The Stem Cell Science Round Up

A 4D Atlas of C. elegans Embryogenesis – Researchers generated a single-cell spatiotemporal atlas of transcription factors in C. elegans embryogenesis.

Lysosomal Regulation of Stem Cell Fate – Scientists found that lysosomal activity regulates hematopoietic stem cell fate.

Ductal and Mesenchymal Cells in Liver Regeneration – Researchers generated liver organoids and found that the ratio and number of contacts between ductal and mesenchymal cells regulate regeneration.

Extending Life Span with VEGF – Researchers found reduced VEGF signaling in key organs in aged mice, and showed that VEGF-treated mice lived longer and had an extended health span.
