Bulletin of Experimental Biology and Medicine is a translation of two Russian journals: Byulleten Eksperimental'noi Biologii i Meditsiny and Kletochnye Tekhnologii v Biologii i Meditsine. 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, and other topics. Recently introduced sections of the journal, entitled Biogerontology and Human Ecology cover novel trends in science. World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal called Cell Technologies in Biology and Medicine. This 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.
