PURPOSE Prostate tumor cells frequently show the features of osteoblasts, which are differentiated from bone marrow mesenchymal stem cells. We examined human prostate cancer cell lines and clinical prostate cancer specimens for additional bone marrow mesenchymal stem cell properties. EXPERIMENTAL DESIGN Prostate cancer cell lines were induced for osteoblastogenic and adipogenic differentiatio...

Bone marrow stromal cells can give rise to several mesenchymal lineages. The existence of a common stem/progenitor cell, the mesenchymal stem cell, has been proposed, but which developmental stages follow this mesenchymal multipotent progenitor is not known. Based on experimental evidence, a model of mesenchymal stem cell differentiation has been proposed in which individual lineages branch dir...

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...

Stem cell-based cellular therapy is a promising tool for the treatment of pathological conditions with underlying severe tissue damage or malfunction like in chronic cardiovascular, musculoskeletal, inflammatory conditions. One biggest technical challenges use natural stem cells, however, prevention their premature senescence during therapeutical manipulations. Culturing cells under hypoxic bel...

Cell therapy using stem cell transplantation against cerebral ischemia has been reported. However, it remains controversial regarding the optimal time for cell transplantation and the transplantation route. Rat models of cerebral ischemia were established by occlusion of the middle cerebral artery. At 1, 12 hours, 1, 3, 5 and 7 days after cerebral ischemia, bone marrow mesenchymal stem cells we...

Mesenchymal stem cells (MSCs) show high expression of PD-L1. Exosomes can transmit signals between tumor and stromal cells; however, the effect tumor-derived exosomes on cell signaling pathways is unclear. The PD-L1 in bone marrow mesenchymal (BMMSCs) was detected by western blot RT-PCR. effects gastric cancer line-derived BMMSC migration conditioned medium from educated BMMSCs were analyzed. O...

Objective(s) Bone marrow is the traditional source of human multipotent mesenchymal stem cells (MSCs), but adipose tissue appears to be an alternative and more readily available source. In this study, rat adipose-derived stem cells (ADSCs) were induced to differentiate into Schwann-like cells and compared with rat bone marrow stem cells (BMSCs) for their Schwann-like cells differentiation pote...

There is great interest in how bone marrow derived stem cells make fate decisions. Numerous studies have investigated the role of individual growth factors on mesenchymal stem cell differentiation, leading to protocols for cartilage, bone and adipose tissue. However, these protocols overlook the role of biomechanics on stem cell differentiation. There have been various studies that have applied...

stem cell therapy has been applied for the treatment of degenerative diseases encompassing corneal disorders.this consideration is regarding the unique characteristics of stem cells including self-renewal and pluripotency. some corneal diseases result from deficiencies in the limbal region. in these conditions, limbal stem cell therapy is considered in which limbal stem cells are cultured in vi...
