Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...

Introduction: During the last decade, advances in tissue engineering and stem cell-based tooth regeneration have provided realistic and attractive means of replacing lost or damaged teeth. The first adult stem cells isolated from dental tissues were dental pulp stem cells (DPSCs). When transplanted with hydroxyl apatite/tri calcium phosphate (HA/TCP) powder, they formed a dentin-like structure...

Background  To report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. Methods: This was a retrospective study of fourteen eyes from 11 healthy individuals. Confocal imaging of cornea and limbus was performed using Heidelberg Retina Tomograph III Rostock Corneal Module. Results: The typical structure of the palisades of Vogt (POV) was detected ...

Introduction there are one million deaths from asphyxia in newborn annually. Management of this newborn is only supportive. Autologuse stem cell therapy may reduce mortality and long term morbidity. Outcome of asphyxiated newborn is related to damage CNS cells. Stem cells prevent Apoptosis and induce repairmen of injured neurons. Methods in a review study all article related to three keyword...

background:  research projects are presented at the annual meetings of the american society for surgery of the hand (assh). it is unknown how many achieve publication in peer-reviewed journals. we sought to determine current rates of publication of podium and poster presentations.   methods:  all assh podium and poster presentations from 2000 to 2005 were reviewed, and an internet-based search ...

Considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. Meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. In enzymatic digestion method extracted teeth as denta...

Background Nowadays using the stem cells has opened a new horizon in the medical science and is indeed a practical and non-invasive method for treating refractory diseases such as Leukemias , lymphomas, blood disorders and so on. Nonetheless, proper and sustainable uses of such powerful cells undoubtedly need to be as per certain ethical principles. of the existing challenges in using stem cel...

Background: Mesenchymal stem cells (MSCs) are multipotent cells, capable of differentiating into different cell lines.They can sense their surrounding biochemical and biophysical factors, which play major roles in their differentiation toward different phenotypes. Therefore, the exposure of these cells to endothelial growth factor (VEGF) as well as hemodynamic biomechanical forces, which act on...

Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data.  This study was designed to e...
