objectives : stem cell (sc) therapy is a promising technique for tissue regeneration. this study aimed to compare the viability and proliferation ability of periodontal ligament stem cells (pdlscs) isolated from the periodontium of healthy and periodontitis-affected teeth to obtain an autologous, easily accessible source of scs for tissue regeneration in periodontitis patients. materials and me...
stem cells located at the limbus , are the ultimate source for regeneration of the corneal epithelium in the normal and traumatized states. when limbal stem cells are dysfunctional or deficient, limbal stem cell deficiency (lscd) develops. its surgical management depends on laterality and severity of corneal-limbal involvement. conventional methods of stem cell transplantation are conjunctiva...
stem cells are undifferentiated cells with the ability of proliferation, regeneration, conversion to differentiated cells and producing various tissues. stem cells are divided into two categories of embryonic and adult. in another categorization stem cells are divided to totipotent, multipotent and unipotent cells. so far usage of stem cells in treatment of various blood diseases has been studi...
Zebrafish can regenerate after brain injury, and the regenerative process is driven by resident stem cells. Stem cells are heterogeneous in the vertebrate brain, but the significance of having heterogeneous stem cells in regeneration is not understood. Limited availability of specific stem cells might impair the regeneration of particular cell lineages. We studied regeneration of the adult zebr...

Introduction Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective: We hypothesi...

De novo shoot regeneration is widely used in fundamental studies and agricultural applications. Actin microfilaments are involved in many aspects of plant cell division, cell morphogenesis and cell signal transduction. However, the function of actin microfilaments during de novo shoot regeneration is poorly understood. Here, we investigated the organization of actin microfilaments during this p...
Regeneration of injured myocardium would offer relief to millions of patients with left ventricular dysfunction. Cell implantation and induction of stem cell-mediated myocardial self-repair represent potential means to achieve myocardial regeneration [1,2]. The latter requires homing of cardiogenic cells to diseased myocardium or activation of resident cardiogenic stem cells. Both mechanisms ha...
Background & Aims: Burning provides irreparable effects on the affected patient. Several studies show that these cells may contribute to tissue regeneration whether through producing a variety of bioactive growth factors and/or by differentiation into mesoderm lineage. Several studies demonstrate that stimulated mesenchymal stem cells have more therapeutic potential than unstimulated cell ...
