The thymic microenvironment constitutes a unique cell environment composed of thymic epithelial cells, myoid cells, and bone marrow-derived accessory cells for the differentiation, maturation and selection of T lymphocytes. The histological feature of thymus is markedly dependent on the age of individual and on various negative stimuli. Our study group consisted of fourteen newborns whose thymu...

The Sertoli cells are critical regulators of testis differentiation and development. In the adult, however, their known function is restricted largely to maintenance of spermatogenesis. To determine whether the Sertoli cells regulate other aspects of adult testis biology we have used a novel transgenic mouse model in which Amh-Cre induces expression of the receptor for Diphtheria toxin (iDTR) s...

Hamartomas can occur in different areas of the breast, but they are rarely found in the breast. Myoid hamartomas with smooth muscle cells of the type described here are particularly unusual. The pathogenesis of this benign entity with its tendency to growth and recurrence is not clear. Excision is the therapy of choice. Capillary hemangiomas are rare vascular malformations of the breast which, ...

objective: electroporation can be a highly efficient method for introducing the foreign genetic materials into the targeted cells for transient and/or permanent genetic modification. considering the application of this technique as a very efficient method for drug, oligonucleotide, antibody and plasmid delivery for clinical applications and production of transgenic animals, the present study ai...

Abstract Testicular development and function rely on interactions between somatic cells the germline, but similar to other organs, regenerative capacity declines in aging disease. Whether adult testis maintains a reserve progenitor population remains uncertain. Here, we characterize recently identified mouse interstitial expressing transcription factor Tcf21. We found that TCF21 lin are bipoten...

Testis is the male reproductive organ that performs both endocrine and exocrine functions. This study aimed to determine distribution of carbohydrates in testis sumba ongole cattle. The sample consisted six were collected from East Sumba Slaughter House, fixed formalin 10 %, processed histologically, continued with AB pH 2,5 - PAS staining. result showed a weak alcian blue intensity (+) tunica ...
