165 citations , October 2013 in “Nature Communications”

This study demonstrates that bioengineered salivary gland transplants can fully regenerate gland function, producing saliva and restoring normal swallowing in salivary gland-defective mice, offering potential for xerostomia treatment.

research Hair Organ Regeneration Via Bioengineered Hair Follicular Unit Transplantation

66 citations , May 2012 in “Scientific Reports”

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

research Fully Functional Hair Follicle Regeneration Through the Rearrangement of Stem Cells and Their Niches

179 citations , April 2012 in “Nature Communications”

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

research Wnt-Dependent De Novo Hair Follicle Regeneration in Adult Mouse Skin After Wounding

829 citations , May 2007 in “Nature”

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

research Integument Pattern Formation Involves Genetic and Epigenetic Controls: Feather Arrays Simulated by Digital Hormone Models

112 citations , January 2004 in “The International journal of developmental biology”

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.
