Mesenchymal stromal cells are a population of undifferentiated multipotent adult cells possessing extensive self-renewal properties and the potential to differentiate into a variety of mesenchymal lineage cells. They express broad anti-inflammatory and immunomodulatory activity on the immune system and after transplantation can interact with the surrounding microenvironment, promoting tissue he...

objective(s) mesenchymal stem cells (mscs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. human mesenchymal stem cells (hmscs) are ideal targets in cell transplantation and tissue engineering. enhanced green fluorescent protein (egfp) has been an important reporter gene for gene therapy. the aim of this stud...

Background  The mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. Stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. This source of stem cells avoids invasive procedures and the ethical controversy of emb...

Multipotent mesenchymal stromal cells (MSCs) are actively involved in reparation and inflammation processes, providing damaged tissue suppressing immune cell responses vivo. The effects mostly due to the production of a wide range paracrine factors, including growth factors immunomodulatory mediators. To induce immunosuppressive activity, MSCs primed by inflammatory cytokines, which results an ...

Mesenchymal stromal cells secrete a variety of anti-inflammatory factors and may provide a regenerative medicine option for the treatment of traumatic brain injury. The present study investigates the efficacy of multiple intravenous or intracardiac administrations of rat mesenchymal stromal cells or human mesenchymal stromal cells in female rats after controlled cortical impact by in vivo MRI, ...

BACKGROUND AND OBJECTIVES The characterization of stem cell microenvironments throughout ontogeny is of fundamental interest in the field of stem cell biology. Within the adult blood system, hematopoietic stem cells (HSC) are supported in the osteoblastic and endothelial bone marrow microenvironments. During mouse mid-gestation, the first HSC emerge autonomously in the aorta-gonad-mesonephros (...

Mitochondria are highly dynamic organelles that in response to the cell's bio-energetic state continuously undergo structural remodeling fission and fusion processes. This mitochondrial dynamic activity has been implicated in cell cycle, autophagy, and age-related diseases. Adult tissue-derived mesenchymal stromal/stem cells present a therapeutic potential. However, to obtain an adequate mesenc...

background susceptibility-weighted imaging (swi) is extremely sensitive in the detection of superparamagnetic iron oxide (spio) nanoparticle-labeled cells. however, no study has compared molecular imaging for stem cell detection using swi and other mri pulse sequences. objectives this study aims to assess the sensitivity of swi in detecting spio nanoparticle-labeled, human bone marrow-derived m...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...
