introduction:first, definition the stem cell refers to those cells that are still not clear and are not equipped for a particular task. these cells have proliferative properties and ability to differentiate into other types of cells have become. this characteristic of stem cells to self-directed has absorbed professional opinion that extensive research is done in this regard. nowadays, stem ce...
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...
Identification and use of cell surface cluster of differentiation (CD) biomarkers have enabled much scientific and clinical progress. We identify a CD surface antigen code for the neural lineage based on combinatorial flow cytometric analysis of three distinct populations derived from human embryonic stem cells: (1) CD15(+)/CD29(HI)/CD24(LO) surface antigen expression defined neural stem cells;...
Background and Aims: It has been proven that human mesenchymal stem cells (MSCs) conditioned medium (hMSCs-CM) can influence human embryonic stem cells (hESCs) chondrogenic differentiation. In this study, we hypothesized that conditioned medium (CM) from hESCs-derived MSCs in a sequential 3D-2D culture system could facilitate the induction of chondrogenesis in hESCs. Materials and Methods: CM ...
