Regeneration: Recorded Live!
Salamanders and fish can regenerate amputated limbs/fins. Which cells drive this intriguing process? Two recent papers have used live imaging of labelled clones of cells to reveal the contribution of connective tissue.

متن کاملLive Monitoring of Blastemal Cell Contributions during Appendage Regeneration
The blastema is a mass of progenitor cells that enables regeneration of amputated salamander limbs or fish fins. Methodology to label and track blastemal cell progeny has been deficient, restricting our understanding of appendage regeneration. Here, we created a system for clonal analysis and quantitative imaging of hundreds of blastemal cells and their respective progeny in living adult zebraf...
متن کاملLive-cell imaging: new avenues to investigate retinal regeneration
Sensing and responding to our environment requires functional neurons that act in concert. Neuronal cell loss resulting from degenerative diseases cannot be replaced in humans, causing a functional impairment to integrate and/or respond to sensory cues. In contrast, zebrafish (Danio rerio) possess an endogenous capacity to regenerate lost neurons. Here, we will focus on the processes that lead ...
متن کاملLive lecture versus video-recorded lecture: are students voting with their feet?
PURPOSE In light of educators' concerns that lecture attendance in medical school has declined, the authors sought to assess students' perceptions, evaluations, and motivations concerning live lectures compared with accelerated, video-recorded lectures viewed online. METHOD The authors performed a cross-sectional survey study of all first- and second-year students at Harvard Medical School. R...
