To investigate whether the CD30 molecule, expressed only by a minority of T and B cells, defines a subtype of T helper cells, Pityrosporum orbiculare-specific CD4+ T cell clones were assessed for CD30 protein and gene expression. The clones were defined as Th1, Th0, and Th2 according to their cytokine mRNA profile detected by reverse transcription PCR (RT-PCR). The kinetics of CD30 expression a...

PURPOSE To culture and characterize oral mucosal epithelial cells (OMEC) grown on de-epithelialized human amniotic membrane (HAM) to explore their suitability as autografts in patients with bilateral ocular surface disease (OSD) and limbal stem cell deficiency. METHODS Oral biopsy samples were obtained from 20 patients undergoing oral reconstructive surgery, with informed consent and Institut...

Transgenic technology, single-cell RT-PCR, and immunocytochemistry were combined to investigate the composition of the GABA(A) receptors of dopaminergic (interplexiform) amacrine (DA) cells. A mouse line was used in which these neurons were labeled with human placental alkaline phosphatase and could therefore be identified in vitro after dissociation of the retina. We performed single-cell RT-P...

PRL is known to be a major secretory product of the human decidua. However, the physiological role of decidual PRL during the menstrual cycle and pregnancy has not been fully defined, primarily due to the lack of an appropriate nonhuman primate model for in vivo studies. Therefore, this initial study examined the expression of PRL and its receptor in the baboon uterus during the cycle and pregn...

Connective tissue growth factor (CTGF) is a cysteine-rich protein that promotes extracellular matrix deposition. CTGF is selectively induced by transforming growth factor beta and des-Arg kallidin in lung fibroblasts and increases steady-state mRNA levels of alpha type I collagen, 5alpha-integrin and fibronectin in fibroblasts. Bronchial epithelial cells have been proposed to functionally inter...

OBJECTIVES The purpose of this study was to investigate the neurogenic differentiation of human dental pulp stem cells (DPSCs), periodontal ligament stem cells (PDLSCs), and stem cells from apical papilla (SCAP). MATERIALS AND METHODS After induction of neurogenic differentiation using commercial differentiation medium, expression levels of neural markers, microtubule-associated protein 2 (MA...

PURPOSE To establish an effective system for isolating primary retinal ganglion cells (RGCs) from newborn mice. METHODS The retinas were separated from enucleated eyeballs of Crl:CD-1 mice on postnatal day 1 to 4. RGCs were purified using three different methods, including two-step immunopanning (TSI), direct magnetic separation (DMS), and immunopanning-magnetic separation (IMS). Harvested ce...

primary cutaneous anaplastic large cell lymphoma is a t-cell malignancy with atypical cd30 positive lymphocytes. pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Human EnSC (endometrial-derived stem cell) is an abundant and easily available source for cell replacement therapy. Many investigations have shown the potency of the cells to differentiate into several mesoderm-derived cell lineages, including osteocytes and adipocytes. Here, the potency of EnSC in neural differentiation has been investigated. Flow cytometric analysis showed that they were posi...
