To evaluate the contributions of cellular memory mechanisms to hematopoietic stem/progenitor cell (HSPC) senescence. HSPCs (Lin-CD117+, hereafter referred to as HSPC) were separated from young (6-week-old) and aged (18-month-old) mice using Magnetic Activated Cell Sorting (MACS). Cell cycle distribution of HSPCs was determined using flow cytometry. The mixed colony forming unit (CFU-Mix) assay ...

OBJECTIVE The patients with anorectal malformations (ARM) have been identified with specific and non-specific pathological changes. The present study was conducted with the aim to study histomorphological changes and various immunohistochemical (IHC) markers (calretinin, S-100, CD117) in intestinal wall specimens to assess neuronal dysfunction in ARM patients. MATERIAL AND METHODS Thirty chil...

BACKGROUND Adult stem cells can contribute to myocardial regeneration after ischemic injury. Bone marrow and skeletal muscles contain a population of CXCR4+ cells expressing genes specific for muscle progenitor cells that can be mobilized into the peripheral blood. The aims of the study were (1) to confirm the presence of early tissue-committed cells expressing cardiac, muscle, and endothelial ...

PURPOSE The aim of this study was to determine the incidence of HER-2/neu, VEGF and CD117 overexpression in soft tissue sarcomas (STS) and to study the effect of this overexpression, if present, on survival in patients with specific histological subtypes of STS. MATERIALS AND METHODS We conducted a retrospective observational study on patients diagnosed with STS during the period of 1986-2001...

Myeloid sarcoma is a rare extramedullary tumor of immature myeloid cells. It has been very rarely reported as lateral cervical mass in English literature. Myeloid sarcoma has also been reported with marked eosinophilia. Here we present a 17 year old boy with lateral cervical mass and persistent eosinophilia. The mass was isointense in MRI and homogenously enhanced after contrast injection which...

Abstract Introduction In 2004, Bornstein reported using immunohistochemical (IHC) analysis of stained sections vestibular specimens, defining diagnostic criteria for neuroproliferative vestibulodynia (NPV). Criteria included presence 8 or more mast cells manually counted in a standardized microscopic field finding total area subepithelial nerve fibers was 10 times higher than controls. Replicat...

Extragastrointestinal stromal tumors (EGISTs) are rare tumors that arise outside the digestive tract. We report a case of an EGIST arising in the subcutaneous tissue of the abdominal wall, which at this site can often be misdiagnosed as dermatofibrosarcoma protuberans. The tumor was surgically resected from a 72-year-old male Chinese Han patient, and pathological examination revealed spindle-sh...

INTRODUCTION Determination of the type of mutations in gastrointestinal stromal tumours (GIST) plays a major role in assessing the risk of progression of the disease, and also allows determination of the clinical management and treatment. More accurate GIST diagnosis is possible by using simultaneously various types of antibodies to immunohistochemistry methods in routine procedures. AIM To e...
