Slow cycling is a common feature shared among several stem cells (SCs) identified in adult tissues including hair follicle and cornea. Recently, existence of unipotent SCs in basal and lumenal layers of sweat gland (SG) has been described and label retaining cells (LRCs) have also been localized in SGs; however, whether these LRCs possess SCs characteristic(More)
Regulation of adult stem cells (SCs) is fundamental for organ maintenance and tissue regeneration. On the body surface, different ectodermal organs exhibit distinctive modes of regeneration and the dynamics of their SC homeostasis remain to be unraveled. A slow cycling characteristic has been used to identify SCs in hair follicles and sweat glands; however,(More)
Histone deacetylases (HDACs) are present in the epidermal layer of the skin, outer root sheath, and hair matrix. To investigate how histone acetylation affects skin morphogenesis and homeostasis, mice were generated with a K14 promoter-mediated reduction of Hdac1 or Hdac2. The skin of HDAC1 null (K14-Cre Hdac1(cKO/cKO)) mice exhibited a spectrum of lesions,(More)
The dual task is a data-rich paradigm for evaluating speech modes of a synthetic talking head. Three experiments manipulated auditory–visual (AV) and auditory-only (A-only) speech produced by text-to-speech synthesis from a talking head (Experiment 1—single task; Experiment 2—dual task), and natural speech produced by a human male similar in appearance to(More)
