SCF/C-Kit Signaling Induces Self-Renewal of Dental Pulp Stem Cells.

Introduction: The maintenance of a stem cell pool is imperative to enable healing processes in the dental pulp tissue throughout life. As such, knowing mechanisms underlying stem cell self-renewal is critical to understand pulp pathophysiology and pulp regeneration. The purpose of this study was to evaluate the impact of stem cell factor (SCF) signaling through its receptor tyrosine kinase (c-Kit) on the self-renewal of human dental pulp stem cells (hDPSCs).

Borrelidin Induces the Unfolded Protein Response in Oral Cancer Cells and Chop-Dependent Apoptosis.

Oral squamous cell carcinoma (OSCC) is the most common cancer affecting the oral cavity, and US clinics will register about 30,000 new patients in 2015. Current treatment modalities include chemotherapy, surgery, and radiotherapy, which often result in astonishing disfigurement. Cancers of the head and neck display enhanced levels of glucose-regulated proteins and translation initiation factors associated with endoplasmic reticulum (ER) stress and the unfolded protein response (UPR).

Morphology of parasympathetic neurons innervating rat lingual salivary glands.

Saliva is essential for taste function and not only does saliva influence taste reception, but also taste perception initiates salivation. As a first step in investigating circuits involved in gustatory-salivary reflexes, we have studied the morphology of the rat inferior salivatory nucleus (ISN), which contains parasympathetic secretomotor neurons that control the parotid and lingual (von Ebner) salivary glands. By applying the fluorescent label Fluorogold to the cut end of the glossopharyngeal nerve, the neurons supplying only the lingual salivary glands were labeled.
