Background: The characteristic of stem cells in self renewal and differentiation to different types of cells has stimulated the interests for using stem cells as a starting material for generating insulin secreting cells. We've evaluated the differentiation potential of Programmable cells of monocytic origin (PCMOs) into insulin producing cells effected from the growth factors and fibroblasts c...
the effect of a neuropeptide, the tachykinin on α-amylase, protease and lipase activities in the midgut of american cockroach, periplaneta americana (linnaeus) is evaluated . immunohistochemical reactivities against tachykinin (tachykinin- ir) were detected in the midgut. tachykinin-ir cells in three regions (anterior, median and posterior) of the midgut were counted in normally fed, starved fo...
The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...
A sequential change in the number of circulating immunoglobulin (Ig) secreting cells of each Ig class following blood transfusion was studied using a reverse hemolytic plaque assay. The subjects studied were in two main groups, immunologically normal individuals and patients with malignant lymphoma or multiple myeloma who are, presumably, immune incompetent. A consistent increase in circulating...

Maintenance of plasma IgM levels is critical for immune system function and homeostasis in humans and mice. However, the mechanisms that control homeostasis of the activated IgM-secreting B cells are unknown. After adoptive transfer into immune-deficient hosts, B lymphocytes expand poorly, but fully reconstitute the pool of natural IgM-secreting cells and circulating IgM levels. By using sequen...
We reported that corticosterone administration into the albumen of fertile chicken eggs on embryonic day (e) 11 induces an increase in the population of GH-secreting cells. The present study evaluated the ontogeny, dose response, localization, and persistence of the glucocorticoid-induced increase in the somatotroph population during chicken embryonic development. Corticosterone (0, 0.02, 0.2, ...
