Glossary In Vivo

experiments conducted within living organisms

"In vivo" is a Latin term meaning "within the living." It refers to experiments or studies conducted in living organisms, such as animals or humans, as opposed to in vitro (outside the living organism, like in a petri dish). This approach allows researchers to observe the natural biological processes and interactions in a complex, real-life environment.

research Dedifferentiation of committed epithelial cells into stem cells in vivo

551 citations , November 2013 in “Nature”

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

research Imaging of zinc oxide nanoparticle penetration in human skin in vitro and in vivo

264 citations , January 2008 in “Journal of biomedical optics”

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

research Skin and hair on-a-chip: in vitro skin models versus ex vivo tissue maintenance with dynamic perfusion

208 citations , January 2013 in “Lab on a Chip”

The researchers described a chip-based bioreactor platform for dynamic perfusion, which may enhance in vitro skin models by introducing mechanical shear stress and extending culture periods.

research In vivo transcriptional governance of hair follicle stem cells by canonical Wnt regulators

173 citations , January 2014 in “Nature Cell Biology”

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

research In vivo and in vitro evaluation of hair growth potential of Hibiscus rosa-sinensis Linn.

128 citations , September 2003 in “Journal of Ethnopharmacology”

This study found that the petroleum ether extract from the leaves of Hibiscus rosa-sinensis demonstrated more effectiveness in promoting hair growth in rats compared to the extract from its flowers.
