L-type voltage-dependent CaV1.2 channels play an important role in the maintenance of intracellular calcium homeostasis, and influence multiple cellular processes. C-terminal cleavage of CaV1.2 channels was reported in several types of excitable cells, but its expression and possible roles in non-excitable cells is still not clear. The aim of this study was to determine whether distal C-termina...
Dental pulp tissue contains dental pulp stem cells (DPSCs). Dental pulp cells (also known as dental pulp-derived mesenchymal stem cells) are capable of differentiating into multilineage cells including neuron-like cells. The aim of this study was to examine the capability of DPSCs to differentiate into neuron-like cells without using any reagents or growth factors. DPSCs were isolated from teet...
Aging is identified by a progressive decline of physiological integrity leading to age-related degenerative diseases, but its causes is unclear. Human dental pulp stem cells (hDPSCs) has a remarkable rejuvenated capacity that relies on its resident stem cells. However, because of the lack of proper senescence models, exploration of the underlying molecular mechanisms has been hindered. Here, we...
Background and Aims: In the last decade, several studies have reported the isolation of stem cell population from different dental sources, while their mesenchymal nature is still controversial. The aim of this study was to introduce the isolating methods for stem cells from human dental pulp and to determine their mesenchymal nature before differentiation. Material and methods: One of the ...
Retinoic acid has been known to play a key role in the regulation of bone cell differentiation and function. The effects of retinoic acid on human dental pulp cells, which contain several characteristics similar to those of bone cells, has yet to be elucidated extensively. The effects of retinoic acid on human dental pulp cells in terms of type I collagen and osteocalcin induction were investig...
OBJECTIVES To investigate the viability and differentiation capacity of dental pulp stem cells (DPSCs) isolated from single donors after 2 years of cryopreservation. METHODS This prospective study was conducted between October 2010 and February 2014 in the Stem Unit, College of Medicine, King Saud University, Riyadh, Saudi Arabia. Seventeen teeth extracted from 11 participants were processe...
Aim: Dental pulp has various characteristics in the pulp chamber, but only a few biological evaluations about the effect of age on dental pulp tissue have been reported. The purpose of this study was to compare dental pulp from young and from adult rats to characterize the homeostatic mechanism. Methodology: Dental pulp cells (DPCs) were obtained from the first molar of rats, weighing 150 g eac...
objective: bioactive glass is often used as a filler material for repair of dental bone defects. in different studies osteogenic potential of this material was proved, but its dentinogenesis property is in doubt. the purpose of this study was to evaluate the histological pulp responses of calcium hydroxide and bioactive glass placed directly on exposed pulp tissues. materials and methods: twent...
Introduction: Researchers have always been interested in the close and mutual relationship between the pulp and periodontal tissues. Although the effects of pulpal disease on periodontium have been well known, the clear relationship between periodontitis and pulp has not been documented . It seems that bacteria and inflammatory products of periodontitis can affect pulp through accessory canals,...
