Dr. Celina Juliano is an Assistant Professor in the Department of Molecular and Cellular Biology at the University of California, Davis. Her lab studies development and regeneration in the aquatic animal Hydra, which undergoes continual self-renewal, lacks senescence and has incredible regenerative capabilities.

The Stem Cell Science Round Up

Oct4 Not Needed for Creating iPSCs – Investigators have discovered that iPSCs can be created without expressing the transcription factor Oct4, which was previously considered vital for cellular reprogramming.

Effect of Spaceflight on Heart Cells – When sent to the International Space Station, iPSC-derived cardiomyocytes readily adapted to microgravity by altering their gene expression, but returned to normal when back on Earth.

Stem Cell Transplants Used to Grow Lungs – Scientists generated functional lungs in mice by transplanting stem cells into genetically defective mouse embryos.

Lymphatic System Key in Hair Regeneration – Investigators have found that stem cells reshape their lymphatic niche to coordinate tissue regeneration.
