introduction: hyperplastic pulpitis (pulp polyp)tissues contains cells with stem cell properties similar to that of the dental pulp stem cells (dpscs). it has also been shown that cd146 enrichment can homogenize the cultures of dpscs and enhance the colony forming potentials of their cultures. this study determines whether cd146 enrichment can help purifying the stem cells from heterogeneous cu...

articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...

background: limited resources for adult stem cells necessitate their in vitro culture prior to clinical use. investigating mitochondrial dna (mtdna) and telomere shortening has proved to be important indications of stem cell validity. this study was designed to investigate these indicators in multiple passages of three adult stem cell lines which were produced in our stem cell laboratory. metho...

stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...

Recent findings in stem cell biology have opened a new window in regenerative medicine. The endometrium possesses mesenchymal stem cells (MSCs) called endometrial stem cells (EnSCs) having specific regenerative properties linked to adult stem cells. They contribute in tissue remodeling and engineering and were shown to have immuno-modulating effects. Many clinical trials were undertaken to asce...

the stem cells can be considered as the miracle of creation, because, they are a major reservoir of the bioactive factors, molecules and cells. these reservoir cells play a major role in development and growth of the tissues and organs. regardless of the differences in differentiation capacity of embryonic and adult stem cells, both the cells are rich sources of stem cells with therapeutic appl...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...
