Tracking diphyodont development in miniature pigs in vitro and in vivo

Biology Open, 2019
Abnormalities of tooth number in humans, such as agenesis and supernumerary tooth formation, are closely related to diphyodont development. There is an increasing demand to understand the molecular and cellular mechanisms behind diphyodont development ...

IFT140+/K14+ cells function as stem/progenitor cells in salivary glands

International Journal of Oral Science, 2022
Stem/progenitor cells are important for salivary gland development, homeostasis maintenance, and regeneration following injury. Keratin-14+ (K14+) cells have been recognized as bona fide salivary gland stem/progenitor cells.

An Eye for an Eye; A Tooth for a Tooth

Survey of Ophthalmology, 2005
A 24-year-old man experienced the sudden onset of a painless superior-temporal visual field defect of the left eye. Fundoscopy showed peripapillary pigmentary changes and a few nasal retinal white spots. Automated perimetry demonstrated an enlarged blind spot.
