the prevalence of spinal cord injury (sci) is about 2.5 million in the worldwide and more than 130,000 new injuries reported each year. regeneration in the cns versus the pns is very different from the other tissues and many factors can prevent regeneration in pns and specially cns. previous researches demonstrated that regeneration of cns can inhibit by inhibitory molecules and glial scar. the...

historically, biomarkers have been used in two major ways to maintain and improve better health status: first, for diagnostic purposes, and second, as specific targets to treat various diseases.   a new era in treatment and even cure for the some diseases using reprograming of somatic cells is about to be born. in this approach, scientists are successfully taking human skin cells (previously co...

multipotent mesenchymal stromal cells or mesenchymal stem cells (mscs) are mainly isolated from bone marrow or fat tissue. because of their potential of multilineage differentiation towards bone, cartilage and fat tissue, they were initially evaluated to develop innovative strategies for tissue engineering applications. more recently, they have gained interest based on their immunomodulatory pr...

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 ...

understanding the molecular mechanisms in regeneration could help the stem cell therapists to improve the clinical practices and could be considered a major milestone in the translation of stem cell research to clinics. chemokines have been described as one of the most significant singling networks in stem cells homing and regeneration of damaged organs. cxcr4/cxcl12 has been known as a key pla...

mesenchymal stem cells (mscs),as the major stem cells for cell therapy, have been studied from different aspects in pre-clinical and clinical settings for more than a decade. these cells modulate the immune system (humoral and cellular immune responses) in vitro by producing soluble factors (anti-inflammatory molecules) and/or making cell-cell contacts. hence they could be used in regenerative ...

The complexity of multiple sclerosis (MS) and the incompetence of a large number of promise treatments in MS urge us to plan new and more effective therapeutic approaches that aim to suppress ongoing autoimmune responses and induction of local endogenous regeneration. Emerging data propose that hematopoietic, mesenchymal and neural stem cells have the potential to restore self-tolerance, to pro...

background: the aim of this research was to evaluate the effect of adipose derived stem cells on bone repair in through and through mandibular bone defects of canine. materials and methods: in this prospective comparative study, adipose-derived stem cells were isolated from subcutaneous fat of lateral thoracic area of 4 dogs. the isolated cells were cultured and expanded through 3 passages. the...

Background Currently, clinical endodontics includes procedures that are based on the ability of stem cells to accomplish repair (eg, direct pulp capping, apexogenesis, apexification, and even pulpal regeneration). An attempt is made to critically assess the current status in pulp regeneration therapy. Methods: Systematically, 2 distinctly different strategies exist involving stem cells for t...

Stem cell-based therapy has great potential in treating health conditions including cardiovascular, autoimmune, type I diabetes, neurodegenerative and bone and cartilage diseases also in spinal cord injuries, malformations and cancer. In addition to their potential use to treat systemic diseases, stem cell-based therapy also provides a powerful tool to treat oral and dental diseases such as cra...
