The aim of the Repository for Biological Sciences Information including its’ new Cell Growth and Cell Membrane resources is to provide reliable information on various areas of scientific interest in a format that can be digested easily. The information is grouped according to interrelated sections and categories and presented in the simplest words and terms possible helping users understand the context of whatever topic information is searched on.

The Biological Cells Section contains scientific information on the basic structural and functional unit of all living organisms. The term “cell” comes from the Latin word “cellula,” which means “a small room” and was coined by Hooke in a book he published in the same year (1665) of his momentous discovery. Cell count can be used as a classification for living organisms. Unicellular organisms have a single cell (most bacteria are included in this category), while multicellular organisms are made up of up to trillions of cells. After inclusion of the two new categories, this section contains ten categories including Cell Binding, Cell Gene, Cell Growth, Cell Membrane, Cell Receptor, Tissue Cells, Cell Treatment, Tumor Cells, In Vitro and In Vivo. This section currently contains over 135,000 articles. Users can receive alerts for newly published content in this section by subscribing to the Biological Cells Section RSS feed.

The newly published category Cell Growth contains scientific information on cell development and cell division. In the context of cell development, cell growth refers to the increase in the volume of cytoplasm, organelles, and genetic material before replication occurs. In contrast, the cell cycle, which is the term used for the process of cell division, comprises the three processes binary fission, mitosis, and meiosis. While the growth of the cell itself is generally different yet related to cell division there are some cells that do not begin the division process until the individual cell has reached a specific size. The category currently contains over 38,500 articles including one on a novel anticancer agent, icaritin, which induced cell growth inhibition, G1 arrest and mitochondrial transmembrane potential drop in human prostate carcinoma PC-3 cells, and one on selenite as a highly effective iron carrier for chinese hamster ovary cell growth and monoclonal antibody production. Website users can receive alerts for newly published content in this category by subscribing to the Cell Growth RSS feed.

The new Cell Membrane category contains scientific information on the cellular membrane, which protects the interior of the cell from the environment surrounding it. The cell membrane is involved in different cellular processes including cell adhesion and cell signaling, as well as being the attachment surface for extracellular structures such as the cell wall, the intracellular cytoskeleton, and glycocalyx. It is, however, also responsible for controlling the movement of different substances in and out of cells. The category currently contains over 32,700 articles including one demonstrating that 5-Hydroxytryptamine4 receptor activation of the extracellular signal-regulated kinase pathway depends on src activation but not on G protein or beta-arrestin signaling, and a novel strategy for preventing human CD8+ cytotoxic T lymphocyte-mediated cytotoxicity against pig endothelial cells by overexpression of pig cellular FLICE-like inhibitory protein c-FLIP gene. Website users can receive alerts for newly published content in this category by subscribing to the Cell Membrane RSS feed.

The repository groups information in the natural sciences according to interrelated sections and categories that will help readers understand the context of whatever topic is searched information on. It is composed of eleven sections which are subdivided into up to ten categories. Each unit contains a definition composed in an understandable way. Each item in these sections and categories contains up to twenty clickable tags. All content is also delivered through RSS feeds.
