Abstract
Epithelial progenitor cells of the primitive pancreatic ducts differentiate in 3 directions, which is accompanied by changes in cell phenotype. We analyze the distribution of the pancreatic and duodenal homeobox 1 (PDX1) in the epithelial cells of pancreatic ducts during the prenatal development in order to determine the potential use of this marker as an indicator of pancreatic cell maturation. Pancreatic autopsies from human fetuses (gestation weeks 17-23) were examined by immunohistochemical methods. In general, PDX1 was detected in the epithelial cells that are involved in various morphogenetic processes related to the growth and branching of the fetal pancreatic ducts. The intensive positive reaction to PDX1/cytokeratin 19 indicates immature (progenitor) polypotent ductal cells.
期刊介绍：
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
