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: In vitro model studies are becoming increasingly popular for experimental research designs. They include isolation and expansion of cells of a particular tissue, such as the nervous tissue which contributes to understanding the underlying mechanisms in many pathologies. It enables  the scrutinization of intracellular signaling pathways responsible for cell death. OBJECTIVES: In the ...

Tissue expansion has become a well-recognized technique for reconstructing a wide variety of skin and soft tissue defects. Its application in the pediatric population has allowed the plastic surgeon to achieve functional and aesthetic goals that were previously unobtainable. This technique can be applied to a variety of reconstructive problems, including the management of giant congenital nevi ...

BACKGROUND Tissue expansion is a concept based on the skin's natural ability to stretch in response to an underlying force. OBJECTIVE The purpose of this article is to review the histological and physiological changes that occur within the soft tissue and underlying structures during tissue expansion. METHODS An extensive search of the literature reviewing these changes is summarized herein...

Until the past decade, optical microscopy of biological specimens was strongly limited by diffraction and scattering, affecting imaging resolution and depth, respectively. Now, numerous methods are available to overcome each of these limitations, but sub-diffraction limited resolution imaging over large volumes of scattering tissue is still a challenge. This work concerns the development of a n...
