Senescent stromal cells support the development of prostate cancer and are considered potential therapeutic targets. This research evaluated the regulatory effects of ginsenoside Rg3 on the senescence of prostatic stromal cells pre-incubated in medium supplemented with 0.5% fetal bovine serum. The results revealed that ginsenoside Rg3 decreased the number of stromal cells positively stained wit...

Endometriosis is an inflammatory disease marked by ectopic growth of endometrial cells. Mesenchymal stromal cells (MSC) have immunosuppressive properties that have been suggested as a treatment for inflammatory diseases. Therefore, the aim herein was to examine effects of allogeneic MSC on endometriosis-derived cells in vitro as a potential therapy for endometriosis. MSC from allogeneic adipose...

Background: Bone marrow stromal cells (BMSC) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. However, the transdifferentiation of BMSC into cholinergic phenotype requires more investigation. Methods: BMSC were isolated from adult rats, pre-induced with β-mercaptoethanol (BME) and followed by nerve growth factor (NGF) indu...

Bone marrow is the point of origin of several cell types, including stromal cells. Adherent bone marrow stromal cells can differentiate into chondrocytes, adipocytes and osteoblasts. Several substances which modulate the dynamics and differentiation of bone marrow stromal cells have been identified. Recently it has been discovered that those bone marrow cells which are non-adherent in tissue cu...

In postmenopausal breast cancers, locally produced estrogen by adipose stromal cells causes the progression of tumor growth. Although aromatase, a key enzyme of estrogen synthesis, is highly expressed in the adipose stromal cells, and aromatase inhibitors show greater efficacy in postmenopausal breast cancers, the mechanism of increasing aromatase activity in the stromal cells remains unclear. ...

Bone marrow stromal cells appear to be key regulatory elements in hematopoiesis and lymphopoiesis. These stromal cells respond to cytokine exposure and alter their pattern of hematopoietic growth factor production, suggesting a degree of functional plasticity. We examined the effect of two cytokines, interleukin-1 (IL-1) and IL-4, on stromal cell regulation of pre-B cell generation using the bo...

Fibroblast-like stromal cells modulate cancer cells through secreted factors and adhesion, but those factors are not fully understood. Here, we have identified critical stromal factors that modulate cancer growth positively and negatively. Using a cell co-culture system, we found that gastric stromal cells secreted IL-6 as a growth and survival factor for gastric cancer cells. Moreover, gastric...

BACKGROUND Mesenchymal stromal cells are employed in various different clinical settings in order to modulate immune response. However, relatively little is known about the mechanisms responsible for their immunomodulatory effects, which could be influenced by both the cell source and culture conditions. DESIGN AND METHODS We tested the ability of a 5% platelet lysate-supplemented medium to s...
