The hypoxia condition was expected to be suitable for the establishment and maintenance of human dental pulp cells (hDPCs), because they reside in a low-oxygen environment in vivo. Therefore, we presently examined the effects of hypoxia on the proliferation and differentiation of hDPCs in vitro. hDPCs grown under 3% O(2) showed a significantly higher(More)
Migration/invasion is involved in the multiple steps of metastasis, resulting in a poor prognosis of breast cancer. (-)-Epigallocatechin-3-gallate (EGCG) in green tea inhibits the metastasis of some cancer cell lines. Cell migration/invasion assays using Boyden chambers demonstrated that (-)-epigallocatechin (EGC), another green tea catechin, inhibited(More)
Human dental pulp cells (hDPCs) are a promising resource for regenerative medicine and tissue engineering and can be used for derivation of induced pluripotent stem cells (iPSCs). However, current protocols use reagents of animal origin (mainly fetal bovine serum, FBS) that carry the potential risk of infectious diseases and unwanted immunogenicity. Here,(More)
We present EnhancedTouch, a novel bracelet-type wearable device for facilitating human-human physical touch. In particular, we aim to support children with autism spectrum disorder (ASD), who often exhibit particular communication patterns, such as lack of physical touch. EnhancedTouch is a unique device that can measure human-human touch events and provide(More)
BACKGROUND Recently, oral sensory complaints (OSC) were proposed as a disease entity to represent idiopathic sensory disturbances of dry mouth, burning mouth, and taste disturbance, even though neither the status of OSC in the general population nor its underlying mechanism has yet been elucidated. Moreover, these three OSC-related complaints have not been(More)
The purpose of this study was to clarify the effect of Chinese propolis on the expression level of neurotrophic factors in dental pulp cells (DPCs). We also investigated that the effects of the conditioned medium (CM) of DPCs stimulated by the propolis against oxidative and endoplasmic reticulum (ER) stresses in human neuroblastoma SH-SY5Y cells, and on(More)
Dental pulp cells (DPCs) of various species have been studied for their potentials of differentiation into functional neurons and secretion of neurotrophic factors. In canine, DPCs have only been studied for cell surface markers and differentiation, but there is little direct evidence for therapeutic potentials for neurological disorders. The present study(More)
The reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) by defined transcription factors has been a well-established technique and will provide an invaluable resource for regenerative medicine. However, the low reprogramming efficiency of human iPSC is still a limitation for clinical application. Here we showed that the reprogramming(More)
